Abstract

PROBLEM TO BE SOLVED: To provide a bivalve farming method in which landed bivalves are received in a farming container submerged under the water of a farming solid partition, and the farmed individual organisms can be fattened in a short term, while an external natural environment water is fluidly supplied and replacing a farming environment water in the farming solid partition.SOLUTION: A farming aquarium 1 with a top surface opened and including an intake 7 and a drain outlet 6 on the other side is constructed and installed in a natural water area blessed with feed materials as a farming solid partition. Also, the landed bivalves (same as the farmed individual organisms) are received in one or multiple farming containers 5 of a structure of transmitting water and preventing the farmed individual organisms from falling off. The farming containers 5 are submerged and disposed under the water in the farming aquarium 1. The natural environment water containing the feed materials is introduced from any water depth in the natural water area into a tank via the intake 7 using a power source 2, continuously supplied to the farming containers 5 by the flow rate larger than the natural water flow, and discharged from the drain outlet 6 to the outside of the tank. Thereby, the farmed individual organisms are fattened for a predetermined period while replacing the farming environment water in the farming aquarium 1.

Description

本発明は、二枚貝の蓄養方法に係り、詳しくはプランクトン(餌料に同じ)を摂食して生長しその外殻が出荷サイズに達した二枚貝を採捕又は収穫(以下、水揚げと総称する)した後、該二枚貝(被蓄養個体に同じ)を生きたまま一時的に蓄養環境下に置いて浄化、治癒、栄養強化、肥育、出荷調整その他の目的管理を行う二枚貝の蓄養方法に関する。   The present invention relates to a bivalve farming method, and in particular, after feeding or growing plankton (same as feed) and harvesting or harvesting bivalve whose outer shell has reached the shipping size (hereinafter collectively referred to as landing) Further, the present invention relates to a bivalve storage method in which the bivalve (same as the individual to be cultivated) is temporarily placed in a storage environment while being alive, and purification, healing, nutrition enhancement, fattening, shipment adjustment and other purpose management are performed.

ここで、蓄養とは、収穫した
養殖魚貝類、又は採捕した天然魚貝類を市場に出荷する前に、これらの魚貝類を浄化、治癒、栄養強化、出荷調整、肥育、シーズン調整などの目的で一定期間、生簀などに収容しておくことである。本発明は、二枚貝の肥育を主目的とした蓄養技術に関するものである。また、プランクトンは、光合成独立栄養生物である植物プラントンを指称するものである。なお、魚貝類は魚介類と同義である。
Here, farming refers to the purpose of purifying, healing, enhancing nutrition, shipping adjustment, fattening, season adjustment, etc. before the harvested cultured fish shellfish or the collected natural fish shellfish are shipped to the market. It is to keep it in a ginger for a certain period. The present invention relates to a farming technique whose main purpose is fattening bivalves. Plankton refers to phytoplankton, which is a photoautotrophic organism. Fish and shellfish are synonymous with seafood.

従来、プランクトンを餌料とする貝類など水産生物の養殖では、天然水域で養殖されその外殻が出荷サイズに達した水産生物の商品価値をさらに高めるために、出荷前の一定期間、養殖物を肥育促進水域に移動させる蓄養が一般的に行われている。   Conventionally, in the cultivation of aquatic products such as shellfish using plankton as feed, the cultured products are fattened for a certain period before shipment in order to further increase the commercial value of aquatic products that have been cultivated in natural waters and whose outer shell has reached the shipping size. Farming to move to the promotion water is generally performed.

また、マガキなど一部の貝類では、生長効率の非常に悪い稚貝の時期に、人工的な水流を供給して稚貝を攪拌することで好適な生長と生残を得る手法が用いられている。   In addition, some shellfish such as oysters use a technique to obtain suitable growth and survival by supplying artificial water flow and stirring the larvae at the time of larvae with very poor growth efficiency. Yes.

ところで、魚貝類の養殖において、魚貝類の発育を促進する技術はほぼ次の5つの手法に分類することが可能である。(1)餌料の供給、(2)餌料が豊富な水域への魚貝類の移動、(3)養殖容器の改善、(4)水流・循環・動揺の各制御、および(5)飼育環境の管理と改善である。   By the way, in the cultivation of fish and shellfish, the technology for promoting the growth of fish and shellfish can be roughly classified into the following five methods. (1) Supply of feed, (2) Transfer of fish and shellfish to water areas rich in feed, (3) Improvement of aquaculture containers, (4) Control of water flow, circulation and shaking, and (5) Management of breeding environment And improvement.

こうしたなかで、餌料の供給技術に関する先行特許文献として、特開2011−223908号公報〔下記特許文献1〕がある。   Under such circumstances, there is JP 2011-223908 [Patent Document 1 below] as a prior patent document relating to a feed supply technology.

この公報には二枚貝の養殖方法および施設が開示されている。養殖池に二枚貝の稚貝の蒔き付けを行い、クルマエビの養殖池を繁殖池として利用して二枚貝の餌となるプランクトンを繁殖させ、繁殖池で培養したプランクトンを順次二枚貝の養殖池に供給しながら養殖を行う。このためアサリ等二枚貝の餌を安定して供給することができる。   This publication discloses a bivalve culture method and facility. While bivalve juveniles are sown in the culture pond, plankton, which is the food for bivalves, is bred using the prawn culture pond as a breeding pond, and plankton cultured in the breeding pond is supplied to the bivalve culture pond in turn. Perform aquaculture. For this reason, bivalve bait such as clams can be supplied stably.

また、特開2011−010637号公報〔下記特許文献2〕には、分子量540以下であり、かつ貯蔵糖あるいは貯蔵糖を構成している糖またはセロビオースを有効成分とする二枚貝飼育剤が開示されている。   Japanese Patent Application Laid-Open No. 2011-010637 [Patent Document 2] discloses a bivalve rearing agent having a molecular weight of 540 or less and containing as an active ingredient sugar or cellobiose constituting the storage sugar or storage sugar. Yes.

この二枚貝飼育剤をアサリ、カキ、アコヤガイ、シジミ等の二枚貝の幼生飼育、初期稚貝の種苗生産、成貝養殖に適用することで、よく肥育した活性の高い貝類の生産が可能である。またこの二枚貝飼育剤を砂抜きの時など、成貝の蓄養時に適用することで、身痩せの防止だけでなく、クエン酸やコハク酸など呈味性の有機酸含量の増加したおいしい二枚貝を得ることにも役立つ。しかしながら、これら餌料の供給技術では、餌料に掛かる費用が蓄養コストを大幅に引き上げる懸念がある。   By applying this bivalve breeding agent to larval breeding of clams such as clams, oysters, pearl oysters, and rainbow trout, seedling production of early larvae, and adult clam culture, it is possible to produce well-fed and highly active shellfish. In addition, this bivalve breeding agent can be applied during the cultivation of adult shellfish, such as when sand is removed, to obtain delicious bivalves that not only prevent leaning but also increase the content of tasty organic acids such as citric acid and succinic acid. Also useful. However, in these feed supply technologies, there is a concern that the cost of the feed significantly increases the farming cost.

また、餌料が豊富な水域への魚貝類の移動に関する特許文献として、特開平10−234248号公報〔下記特許文献3〕がある。   Further, as a patent document relating to the movement of fish and shellfish to a water area rich in food, there is JP-A-10-234248 [Patent Document 3 below].

この公報には殻付きカキの養殖方法が開示されている。カキの種付着器を筏垂下式にする養殖方法において、波が荒くなく台風にも影響されない養殖域に、垂下連を吊り下げた状態で一定期間養殖を行い、カキが所定の大きさに成長した段階で、垂下連を一旦引き揚げて、垂下連のまま又は垂下連からネット袋にカキを入れ替えて、別途はなれたプランクトンの豊富な身入り漁場へと移動させて、垂下連又はネット袋を再度吊り下げて養殖を行い、殻付き状態のままでカキを大きく成長させる。しかしながら、この技術では、養殖域から身入り漁場への移動のための労力を必要とする。垂下連からネット袋へのカキの入れ替えを選択する場合にはさらに多くの労力を必要とする。   This publication discloses a method for culturing shelled oysters. In the culture method that makes the oyster seed applicator a pendulum type, the oyster grows to a predetermined size by cultivating the oyster seed hanging device for a certain period in a culture area where the waves are not rough and are not affected by typhoons while hanging the droop At this stage, the drooping station is lifted once, and the oysters or the net bag is again transferred to the fishing ground where abundant plankton is abundant, replacing the oysters in the drooping station or from the drooping station to a net bag. Suspend to cultivate and grow oysters in a shelled state. However, this technique requires labor for moving from the aquaculture area to the fishing ground. More effort is required to replace the oysters from the droop to the net bag.

養殖容器の改善に関する先行特許文献として、特表平11−503020号公報〔下記特許文献4〕がある。この公報には養殖対象物である軟体動物が使用中にコンテナの中で転動する養殖装置が開示されている。   As a prior patent document relating to the improvement of the aquaculture container, there is JP-T-11-503020 [Patent Document 4 below]. This publication discloses an aquaculture device in which a mollusk that is an aquaculture object rolls in a container during use.

ここでは、軟体動物を養殖するための回転可能に支持されたコンテナと、水位の変化に応答する浮揚部材、この浮揚部材に回転可能に取り付けられた梃子と、浮揚部材と梃子の動きに応答してコンテナの回転運動を達成する手段とを備え、コンテナの回転によって軟体動物を栄養物に均等に接近させることで、軟体動物の均一な成長が可能となり、さらに成長フリルを除去することによって均一な貝殻形状になる。しかしながら、この技術では、コンテナの製造コストが蓄養コストを引き上げる懸念や、コンテナへの各種海洋付着物による回転阻害の懸念がある。   Here, a rotatably supported container for aquaculture of mollusks, a buoyant member responsive to changes in water level, an insulator rotatably attached to the buoyant member, and responsive to movement of the levitation member and the insulator. Means for achieving the rotational movement of the container, and by making the mollusk evenly approach the nutrients by rotating the container, the mollusk can grow evenly and further by removing the growth frills It becomes a shell shape. However, with this technology, there is a concern that the manufacturing cost of the container will increase the farming cost, and there is a concern that rotation will be inhibited by various marine deposits on the container.

また、水流・循環・動揺の各制御に関する先行特許文献として、特開2006−304676号公報〔下記特許文献5〕がある。この公報には海産稚貝の飼育方法が開示されている。採苗後の海産稚貝を中間育成するための海産稚貝の飼育方法の改善を目的とし、底面をメッシュ形成した飼育容器に採苗後の海産稚貝を収容して海水中に半沈設又は半没水設置し、容器内に海水を給排しながら育成する。   Moreover, there exists Unexamined-Japanese-Patent No. 2006-304676 [following patent document 5] as a prior patent document regarding each control of water flow, circulation, and shaking. This publication discloses a method for raising marine larvae. For the purpose of improving the breeding method of marine larvae for intermediate growth of marine larvae after seedling, the marine larvae after seedling are housed in a breeding container with a meshed bottom and semi-sunk in seawater or Set up semi-submersible and grow while supplying and discharging seawater in the container.

ここでは、飼育容器は樹脂製ポットで、これらは海面筏から懸垂され、波浪により揺動又は振動可能に保持される。また、海水の給排は、餌料が豊富で付着生物の少ない水深から採取した海水を容器開口上部から流下供給し容器底部より開放排水する。   Here, the breeding containers are resin pots, which are suspended from the sea surface and are held so that they can be swung or vibrated by waves. In addition, seawater is fed and drained from the top of the container opening and drained from the bottom of the container by supplying seawater collected from a depth of food with abundant feed and few attached organisms.

しかしながら、この技術は稚貝の中間育成技術であり、この技術を外殻が出荷サイズにまで成長したカキへ適用すると、養殖水域面積当りの蓄養数に限界があり効率的な蓄養ができないという懸念がある。   However, this technology is an intermediate breeding technology for juvenile shellfish, and there is a concern that when this technology is applied to oysters whose outer shells have grown to the shipping size, there is a limit to the number of farms per aquaculture area and efficient farming is not possible. There is.

また、実用新案登録第3108828号公報〔下記特許文献6〕には貝類を蓄養する循環蓄養装置が開示されている。この装置は、蓄養水槽、フィルター槽、濾過槽、殺菌槽、熱交換器付ポンプ槽によって一体的に構成される。   Also, utility model registration No. 3108828 [Patent Document 6 below] discloses a circulation farming device for farming shellfish. This apparatus is integrally configured by a storage water tank, a filter tank, a filtration tank, a sterilization tank, and a pump tank with a heat exchanger.

その蓄養水槽には、底部の所定位置に排水口を設けると共に、各種構成材料よりなる仕切板に縦設し、この仕切板には、一方の端部を壁面等に固定部を設けて取着け、他方の端部には所定間隔の開放した循環流水路を形成して一方の循環を強制的に流水させる。これにより新鮮な海水等を供給し成育と蓄養とを著しく向上できるとしている。しかしながら、この技術は陸上での蓄養技術のため、天然水域での蓄養と比較し全体的にコスト高となる懸念がある。   The storage tank is provided with a drain outlet at a predetermined position on the bottom, and is vertically installed on a partition plate made of various constituent materials. One end of this partition plate is fixed to a wall surface and attached. The other end portion is formed with a circulating water channel having a predetermined interval, and one of the circulations is forced to flow. In this way, fresh seawater and the like can be supplied to significantly improve growth and farming. However, since this technique is a farming technique on land, there is a concern that the cost will increase overall as compared to farming in natural waters.

また、飼育環境の管理と改善に関する先行特許文献として、特開2003−158942号公報〔下記特許文献7〕がある。この公報には養殖貝類用酸素供給装置及び養殖貝類用酸素供給方法が開示されている。   Moreover, there exists Unexamined-Japanese-Patent No. 2003-158942 [following patent document 7] as a prior patent document regarding management and improvement of breeding environment. This publication discloses an oxygen supply device for cultured shellfish and an oxygen supply method for cultured shellfish.

ここで、酸素供給装置はカキ、アコヤ貝あるいはホタテ貝等の貝類を養殖するための養殖筏に取付けられ、溶存酸素量の多い表層部の海水(表層水)を、溶存酸素量の少ない底層部へ供給する。これにより底層水の溶存酸素量を容易に増やして、底層水で養殖される貝類の生育を促進することができるとしている。しかしながら、この技術では貝類の斃死を防ぐことは可能であるが、肥育に必要となる餌料の摂取量は変わらないので、その肥育効果は大きくないという懸念がある。   Here, the oxygen supply device is attached to an aquaculture cage for culturing shellfish such as oysters, oysters, scallops, etc., and the seawater (surface water) with a large amount of dissolved oxygen is used as the bottom layer with a small amount of dissolved oxygen. To supply. Thereby, it is said that the amount of dissolved oxygen in the bottom layer water can be easily increased, and the growth of shellfish cultured in the bottom layer water can be promoted. However, although this technique can prevent shellfish from dying, there is a concern that the feed intake necessary for fattening does not change, and the fattening effect is not great.

さらに、特開2009−038999号公報〔下記特許文献8〕にはマガキ蓄養装置が開示されている。この装置には、身入状態に養殖されたマガキを蓄養温度に維持する蓄養恒温槽、この蓄養恒温槽に清浄海水を供給する海水前処理手段と、蓄養恒温槽内の海水を浄化して再使用に供する循環手段が備えられている。   Furthermore, a Japanese oyster farming device is disclosed in Japanese Unexamined Patent Publication No. 2009-038999 [Patent Document 8 below]. This device includes a thermostatic bath that maintains the oysters cultured in the state of cultivation at the storage temperature, seawater pretreatment means that supplies clean seawater to the storage thermostat, and purifies and recycles the seawater in the storage thermostat. Circulation means are provided for use.

この技術の目的は、安定した高品質のマガキを年間を通じて、特に海水の温度が上昇する時期にも供給することである。蓄養中は清浄な循環海水中に浮遊するプランクトンを餌としている。しかしながら、この技術は陸上での蓄養技術のため、天然水域での蓄養と比較し全体的にコスト高となる懸念がある。   The purpose of this technology is to provide stable and high quality oysters throughout the year, especially when seawater temperatures rise. During farming, they feed on plankton floating in clean circulating seawater. However, since this technique is a farming technique on land, there is a concern that the cost will increase overall as compared to farming in natural waters.

まず、従来技術の問題点を総括すると、肥育促進水域を利用した二枚貝の蓄養工程における肥育は水域の餌量に頼ったものであり、餌量は随時変化するため、年間を通して一定の効果を得ることはできない。したがって、肥育促進水域の利用効果は比較的餌量が多い時期に限られていた。   First, to summarize the problems of the prior art, fattening in the bivalve farming process using fattening promotion water area depends on the amount of food in the water area, and the amount of food changes from time to time, so it obtains a certain effect throughout the year It is not possible. Therefore, the utilization effect of the fattening promotion water area was limited to a period when the amount of food was relatively large.

また、稚貝期における人工水流供給による成長促進効果は、水流によって対象物が攪拌できるほど小さいサイズである稚貝期にその利用は限られており、商品サイズに達した蓄養対象物に対する餌の供給には利用できなかった。   In addition, the growth promotion effect of artificial water supply during the juvenile season is limited in the juvenile season where the target can be agitated by the water stream, and its use is limited. It was not available for supply.

また、二枚貝のうち、特に殻付きのカキ類、アサリ、シジミ、ハマグリなどでは、殻の大きさが市場へ出荷できる商品サイズに達していても、内部の身のサイズ・質量が殻の大きさに応じた十分な水準に達しているとは限らない。しかも内部の身のサイズ・質量は消費直前に開殻するまで生産者をはじめ、飲食店の調理人や消費者にはわからない。   Among bivalves, especially oysters with shells, clams, swordfish, clams, etc., even if the shell size has reached the product size that can be shipped to the market, the size and mass of the inside body is the size of the shell. It does not necessarily reach a sufficient level according to Moreover, the size and mass of the inside are not known by producers, restaurant cooks, or consumers until the shell is opened immediately before consumption.

この結果、調理人や消費者が殻付き二枚貝を調理あるいは消費するために開殻した際、身の小さい肥育不良の二枚貝を見出す場合が少なくない。   As a result, when cooks and consumers open shells for cooking or consuming shelled bivalves, they often find small biphasic mussels with poor fattening.

このため二枚貝の生産者は、肥育不良の個体数割合を見込んで注文数よりも多い数の二枚貝を出荷せざるを得ない状況にある。そこで、年間を通して水揚げ後の殻付き二枚貝の身のサイズ・質量をその殻の大きさに見合った高い水準に揃えるための短期間高効率肥育技術が求められていた。   For this reason, bivalve producers are forced to ship more bivalve molluscs than ordered in anticipation of the proportion of poor fattening individuals. Therefore, short-term high-efficiency fattening technology was required to align the size and mass of shelled bivalves after landing to a high level commensurate with the size of the shell.

これらの問題点に対し、上記特許文献に記載された公知技術は一定の効果を示す。しかしながら、これらの技術についても費用対効果や効率性に関する課題が認められる。以下(イ)〜(ホ)に、主な懸念としてまとめる。   For these problems, the known techniques described in the above-mentioned patent documents show a certain effect. However, these technologies also have problems related to cost effectiveness and efficiency. The main concerns are summarized below in (a) to (e).

(イ)餌料に掛かる費用が蓄養コストを大幅に引き上げる懸念がある。
(ロ)多くの労力とそれに伴うコストを必要とする場合があることへの懸念がある。
(ハ)蓄養容器コストが蓄養コストを引き上げる懸念がある。
(ニ)蓄養水域面積当りの蓄養数の限界から生じる非効率性への懸念がある。
(ホ)陸上での蓄養技術のため、天然水域での蓄養と比較し全体的にコスト高となる懸念がある。
(B) There is a concern that the cost of food will greatly increase the cost of farming.
(B) There is concern that it may require a lot of labor and associated costs.
(C) There is a concern that farm container costs will increase farm costs.
(D) There is concern about inefficiency arising from the limit of the number of farms per farm water area.
(E) Due to the farming technology on land, there is a concern that the overall cost will be higher compared to farming in natural waters.

本発明者らは、上記課題や懸念を解決するために鋭意研究を行った結果、天然水域の蓄養立体区画(代表的には半閉鎖的な水槽)において、動力を利用して天然水域の水(天然環境水に同じ)を取水し、水流を発生させて蓄養対象物(被蓄養個体に同じ)に流動供給することにより、蓄養環境下で天然環境水に含まれるプランクトンの摂食機会又は摂餌量を増補し、普通肥育の場合よりも短期間で好適な肥育促進効果を発揮する人工的な管理環境下での蓄養手法を開発した。なお、蓄養環境が人工的な管理環境として設定されるという点で、天然水域の蓄養立体区画の構設という設置条件は、天然水域沿岸に陸上設置した蓄養設備(水槽や動力源を含む)に代替することも考慮されてよい。   As a result of diligent research to solve the above-mentioned problems and concerns, the inventors of the present invention have used water in a natural three-dimensional recreation area (typically a semi-closed aquarium) using power. By taking water (same as natural environment water), generating a flow of water and supplying it to the farming target (same as the individual to be cultivated), feeding opportunities or consumption of plankton contained in the natural environment water in the farming environment We have developed a farming technique under an artificial management environment that increases the amount of feed and exhibits a suitable fattening promotion effect in a shorter period of time than normal fattening. In addition, the installation condition of the construction of the three-dimensional section of the natural water area is that the farming environment is set as an artificial management environment, the storage conditions (including aquarium and power source) installed on the coast of the natural water area Alternatives may also be considered.

本発明はこのような事情に鑑みなされたものであって、上記課題を解消し、水揚げした二枚貝を蓄養立体区画の水面下に沈設した蓄養容器内に収容し、天然環境水を流動的に供給して、蓄養立体区画内の蓄養環境水を入替えながら、所定期間にわたり被蓄養個体を肥育するようにしたことを特徴とする二枚貝の蓄養方法を提供するものである。   This invention is made | formed in view of such a situation, Comprising: The above-mentioned subject was solved, and the landed bivalve was accommodated in the storage container set up under the surface of the storage three-dimensional division, and natural environment water was supplied fluidly Thus, a bivalve farming method is provided in which the farmed individual is fattened over a predetermined period while replacing the farm environment water in the farm three-dimensional compartment.

課題を解決するために本発明は、二枚貝の蓄養方法において、
水揚げされた二枚貝(被蓄養個体に同じ)を透水性の蓄養容器に収容し、天然水域の任意の水深から餌料を含んだ天然環境水を動力を利用して供給し、所定期間にわたり餌料の摂食機会又は摂餌量を増補することにより被蓄養個体を肥育するようにしたことを特徴とするものである。
In order to solve the problem, the present invention provides a bivalve farming method,
The landed bivalve (same as the individual to be farmed) is placed in a permeable storage container, and natural environmental water containing food is supplied from any depth in the natural water area using motive power. It is characterized by fattening a farmed individual by increasing food opportunities or food intake.

より詳しくは、上記二枚貝の蓄養方法において、天面が開口し他面に取水口と排水口を備えた蓄養水槽を、餌料に恵まれた天然水域に蓄養立体区画として構設又は該天然水域沿岸に陸上設置するとともに、水揚げされた二枚貝(被蓄養個体に同じ)を、水を透過し、かつ、該被蓄養個体が脱落しない構造の1又は複数の蓄養容器に収容し、該蓄養容器を前記蓄養水槽内で水面下に没水させて配置し、前記天然水域の任意の水深から餌料を含んだ天然環境水を前記取水口を介し動力を利用して前記蓄養水槽内に導入し、自然水流よりも大きい流量で連続的に前記蓄養容器に供給し、前記排水口から前記蓄養水槽外へ排出することにより、該蓄養水槽内の蓄養環境水を入替えながら所定期間にわたり前記被蓄養個体を肥育するようにしたことを特徴とするものである。   More specifically, in the bivalve farming method described above, a farm tank with a top opening and a water intake and a drain outlet on the other side is constructed as a farming three-dimensional section in a natural water area blessed with food or on the coast of the natural water area. The landed bivalve (same as the farmed individual) is housed in one or more farming containers that have a structure that allows water to pass through and that the farmed individual does not fall off. In the aquarium, submerged under the surface of the water and placed in the recreational water tank using natural environmental water containing feed from any depth of the natural water area through the intake, using natural water flow So that the farmed individual is fattened over a predetermined period of time while replacing the farm environment water in the farm water tank by supplying the farm container continuously with a large flow rate and discharging it from the drain outlet to the outside of the farm water tank. Specially It is an.

本発明によれば、これまで利用してきた天然水域等を利用して、従来の天然水域のコンディション(設置環境に限定されるプランクトン量)に依存した肥育より効果的な蓄養肥育を行うことができる。   According to the present invention, it is possible to perform storage and fattening more effectively than fattening depending on the condition of the conventional natural water area (plankton amount limited to the installation environment) using the natural water area or the like that has been used so far. .

しかも、肥育操作(蓄養管理)が天然水域(天然環境水)を利用して短期間で効果的に行えるので、高品質、計画生産が可能であり商品価値の向上に寄与することが期待できる。さらに、本発明方法は環境水に栄養添加するものではないため、環境負荷がほとんどない。   In addition, since fattening operations (cultivation management) can be effectively performed in a short period of time using natural water areas (natural environmental water), it is possible to achieve high quality, planned production and contribute to the improvement of commercial value. Furthermore, since the method of the present invention does not add nutrients to the environmental water, there is almost no environmental load.

後述するように、本発明方法は、所謂シングルシード養殖技術、とりわけマガキのシングルシード養殖の出荷前肥育技術を確立し、オイスターバー等への安定供給が期待できる点で、産業上の利用可能性は大である。   As will be described later, the method of the present invention has a so-called single seed aquaculture technique, in particular, a pre-shipment fattening technique for single seed aquaculture of oysters, and can be expected to be stably supplied to oyster bars, etc. Is great.

Is a bivalve farming method that performs purification, healing, nutrition enhancement, fattening, shipment adjustment and other purpose management in a farming environment, and provides a semi-enclosed farming three-dimensional section in natural waters. Substituting a permeable storage container under the surface of the water, accommodating the individual to be cultivated, constructing a cultivating environment, introducing external natural resource water in the vicinity of the three-dimensional cultivated compartment using a power source, Is generated and supplied to the farmed individual so that the feeding opportunity or the feeding amount of the feed is increased while replacing the farming environmental water in the section.

好適な実施形態では、半閉鎖的な蓄養立体区画が、天面と他面の給排水に係る操作領域を開放した蓄養水槽を用いるものであり、透水可能な蓄養容器が網籠である。   In a preferred embodiment, the semi-closed storage three-dimensional section uses a storage water tank in which an operation area related to water supply and drainage on the top surface and the other surface is opened, and the water-permeable storage container is a net cage.

また、水流の発生が、蓄養立体区画の全周囲から方向選択されるものであり、外部天然環境水の導入が動力を利用して天然水域の任意の水深から取水選択されるものであり、蓄養環境水の入替えが前記蓄養立体区画内外への給排水操作である。通常、水深範囲は0.2〜5mである。   In addition, the generation of water flow is selected from the entire circumference of the storage three-dimensional compartment, and the introduction of external natural environmental water is selected from any depth of the natural water area using power, The replacement of the environmental water is a water supply / drainage operation into and out of the three-dimensional storage area. Usually, the water depth range is 0.2-5 m.

また、被蓄養個体がカキ、アサリ、シジミその他の二枚貝であり、蓄養立体区画内に並列設置および/または多段設置したそれぞれの蓄養容器に1個体又はそれ以上の個体群を収容するものである。   The farmed individuals are oysters, clams, rainbow trout and other bivalves, and one or more individuals are accommodated in each farming container installed in parallel and / or in multiple stages in the farmed three-dimensional compartment.

さらに、至適にはカキがマガキであって、養殖により出荷サイズ(後述の商品サイズに同じ)に成長した個体を水揚げして蓄養に供するものである。   Furthermore, the oyster is optimally a oyster, and an individual that has grown to a shipping size (same as the product size described later) by aquaculture is landed and used for farming.

本発明の一実施例を添付図面を参照して以下詳説する。   An embodiment of the present invention will be described below in detail with reference to the accompanying drawings.

図1は、本発明方法の原理を示す蓄養装置の側面視概要説明図である。当然のことながら、蓄養装置は本発明方法を実施するために用いられるものである。   FIG. 1 is a side view schematic explanatory diagram of a farming apparatus showing the principle of the method of the present invention. Naturally, the farming device is used for carrying out the method of the present invention.

図1に示すように、棲息や養殖に適した天然水域に浮体とアンカー機能を持つ蓄養立体区画、具体的には半閉鎖的な蓄養水槽1を構設する。したがって、既存の養殖設備に付属する形態であってもよい。   As shown in FIG. 1, a three-dimensional section having a floating body and an anchor function, specifically a semi-closed storage tank 1 is constructed in a natural water area suitable for habitat and aquaculture. Therefore, the form attached to the existing aquaculture equipment may be sufficient.

蓄養水槽1は、動力源2を用いて起こした水流が拡散して効果を失うことを防ぐため、少なくとも3面以上を有する。これによって、動力源2から発生した水流は矢印3の方向へ流れる。この水流の方向は、横方向の他に下から上、上から下の垂直方向や円方向などであっても良い。また、蛇行させることで肥育効果が向上する可能性も期待できる。   The farm water tank 1 has at least three or more surfaces in order to prevent the water flow generated using the power source 2 from diffusing and losing the effect. Thereby, the water flow generated from the power source 2 flows in the direction of the arrow 3. The direction of the water flow may be a vertical direction from the bottom, a vertical direction from the top to the bottom, a circular direction, or the like in addition to the horizontal direction. In addition, the possibility of improving the fattening effect by meandering can be expected.

被蓄養個体は蓄養容器5に収容し、水流が行き届くようにする。蓄養容器5は水域の水面4に依存して冠水するよう蓄養水槽1内に沈設する。水流は最終的に排水口6若しくは容器の天面(上面)から排水する。取水口7は、任意の水深から取水できる構造とし、使用する季節の水域の水温や餌環境に応じて水深を調節する機能を持たせる。   The farmed individual is accommodated in the farming container 5 so that the water flow can reach. The farm container 5 is set in the farm tank 1 so as to be submerged depending on the water surface 4 of the water area. The water flow finally drains from the drain 6 or the top surface (upper surface) of the container. The intake port 7 has a structure capable of taking water from an arbitrary depth, and has a function of adjusting the water depth according to the water temperature and the bait environment of the water area in use.

要するに、外部天然環境水の槽内供給を受けた蓄養環境水が、カキなどの蓄養対象物(被蓄養個体)にとってプランクトンの摂食機会又は摂餌量を増補するような流動環境(入替えを含む)を創出できればよい。   In short, the farming environment water supplied in the tank of the external natural environment water is a fluid environment (including replacement) that increases the plankton's feeding opportunity or the feeding amount for oysters and other farming objects (cultivated individuals) ) Can be created.

図2は、本発明方法の工程フロー説明図である。   FIG. 2 is an explanatory diagram of the process flow of the method of the present invention.

図3は、本発明方法を実施するために用いる蓄養装置の側面視概要説明図である。ここでは、図1とは異なる符号体系を用いている。なお、筏を海面に固定するアンカーは図示をしていない。当然のことながら、図3から看取される装置規模の拡縮は、本発明の要旨を逸脱しない限りにおいて許容される。   FIG. 3 is a side view schematic explanatory diagram of a farming device used for carrying out the method of the present invention. Here, a different coding system from FIG. 1 is used. The anchor for fixing the anchor to the sea surface is not shown. As a matter of course, the expansion and contraction of the device scale seen from FIG. 3 is allowed without departing from the gist of the present invention.

試験区として、蓄養水槽303 は上面が開口した5面の直方体としている。より具体的には、垂下式養殖に使用されるフロート102 付き筏101a(101b)の水面下にFRP製水槽〔長さ:約10m,幅:約2m,深さ:約0.6m〕を沈設し、筏フレーム101a(101b)から蓄養容器を垂下(懸吊)している。図示の蓄養容器301 は、所謂、提灯かごである。一般的な提灯かごの底面は350mm角である。   As a test zone, the farm water tank 303 is a rectangular parallelepiped having five surfaces with an upper surface opened. More specifically, an FRP water tank (length: about 10 m, width: about 2 m, depth: about 0.6 m) is set below the surface of the ridge 101a (101b) with a float 102 used for hanging culture. The farm container is suspended (suspended) from the rod frame 101a (101b). The illustrated farm container 301 is a so-called lantern basket. The bottom of a typical lantern basket is 350 mm square.

この寸法形状の場合、商品サイズのマガキがお互いに重なり合わないで蓄養できるマガキ収容個数は、1かごあたり約50個である。なお、蓄養容器として提灯かご以外にも公知の積層型樹脂製かご〔図示省略〕を用いる場合がある。いずれの蓄養容器も、それらの表面に生物付着防止処理がなされることが好ましい。   In the case of this size and shape, the number of postcards that can be cultivated without overlapping the product-size postcards is about 50 per car. In addition to a lantern cage, a well-known laminated resin cage [not shown] may be used as a storage container. Any of the storage containers is preferably subjected to biological adhesion prevention treatment on the surface thereof.

なお、図示のとおり、蓄養水槽303 の底面から約100mm上に網304 を設置するのが好ましい。蓄養容器301 が蓄養水槽303 の底面にべた付きになって、蓄養容器301 内外の水流が抑制されたり、停止したりする弊害を防止するためである。   In addition, it is preferable to install the net | network 304 about 100 mm above the bottom face of the storage tank 303 as shown in the figure. This is because the farm container 301 becomes sticky to the bottom surface of the farm water tank 303 to prevent the adverse effect that the water flow inside and outside the farm container 301 is suppressed or stopped.

動力源として小型船舶201 用の推進機関である回転プロペラ202 を用い、FRP製水槽303 に開口部303a(取水口に同じ)を設けて水流Bを供給した。水流速度は約0.05m/secから約1.00m/secまでの範囲で設定が可能である。   A rotating propeller 202, which is a propulsion engine for a small vessel 201, was used as a power source, and an opening 303a (same as the intake port) was provided in the FRP water tank 303 to supply the water flow B. The water flow velocity can be set in a range from about 0.05 m / sec to about 1.00 m / sec.

図示の提灯かご301 の設置構成(直列2段)では、0.25m/secの水流速度で蓄養した。流速が0.25m/secより大きいと、提灯かご301 が傾いて、マガキ302 ・・302 (被蓄養個体群)が寄り集まってしまうという不都合が発生するからである。   In the installation configuration of the illustrated lantern basket 301 (two stages in series), the farm was farmed at a water flow velocity of 0.25 m / sec. This is because when the flow velocity is higher than 0.25 m / sec, the lantern basket 301 tilts and the oysters 302... 302 (contained population) gather together.

そして、図示のとおり、回転プロペラ202 によって発生した水流を、FRP製水槽303 の開口部303a(側壁面がない片側短辺)から水槽303 内に導入し、対面の短辺から水槽303 の外部へオーバーフローさせるようにしている。   Then, as shown in the figure, the water flow generated by the rotating propeller 202 is introduced into the water tank 303 from the opening 303a (one side short side without the side wall surface) of the FRP water tank 303, and from the short side opposite to the outside of the water tank 303. It is made to overflow.

そこで、商品サイズに達したマガキ1,000個を水揚げし、FRP製水槽303 に20体(横方向2列×縦方向5列×深さ方向2段)の提灯かご301 に50個ずつ収容し、本発明方法により3週間蓄養した。   Therefore, 1,000 oysters that reached the product size were landed, and 50 lantern baskets 301 were accommodated in FRP water tanks 303 in 20 lantern baskets 301 (2 rows x 5 rows x 2 depths). The animals were reared for 3 weeks according to the method of the present invention.

同時に対照区として、同じロットの(同じ海域から水揚げした)商品サイズに達したマガキ100個を提灯かご2段に分散収容し、同海域に垂下し、試験区と同じ期間で通常肥育を行った。〔図示省略〕   At the same time, as a control plot, 100 oysters of the same lot (landed from the same sea area) that reached the product size were distributed and housed in two lantern baskets, suspended in the sea area, and subjected to normal fattening in the same period as the test area. . (Not shown)

3週間後にそれぞれの蓄養方法で肥育したマガキを任意に各50個抽出し、これらのマガキの全重量とむき身(軟体部)の重量を測定し、全重量に対するむき身の割合〔身入率(%)=むき身重量 [A] /全重量 [B] ×100〕を算出して比較した。その結果を表1に示す。   Three weeks later, 50 oysters fattened by each farming method were randomly extracted, and the total weight of these oysters and the weight of the flesh (soft body) were measured. ) = Peeled weight [A] / total weight [B] × 100] were calculated and compared. The results are shown in Table 1.

Figure 2015119664
Figure 2015119664

表1に示すとおり、通常肥育のマガキでは平均29.9%だったのに比べ、本発明方法により蓄養したマガキでは平均31.8%と、むき身部分の重量が相対的に大きくなる肥育効果が確認できた。なお、表1中に記載の身入れ促進機とは本発明方法における蓄養装置(の蓄養容器)を指称するものである。   As shown in Table 1, the average of fattening oysters was 29.9%, compared to the average of 31.8% for oysters cultivated by the method of the present invention. It could be confirmed. In addition, the maintenance promotion machine described in Table 1 refers to a farming device (a farming container) in the method of the present invention.

品質の特徴としては、深い殻で身入りが良く白色部分(蓄積物質であるグリコーゲン)の呈色も良いこと、丸みがあり若い身特有の歯触りが良いこと等が挙げられる。もちろん、高度衛生管理により海外の食品衛生規格(例えば、アメリカのFDA)にも対応可能である。   The quality features include a deep shell and good white color (glycogen, which is a stored substance), and a rounded and unique texture. Of course, it is possible to cope with overseas food hygiene standards (for example, US FDA) by advanced hygiene management.

種苗生産(屋内種苗育成)から中間育成を経て海面養殖(シングルシード養殖)を行う育成期間の短縮化に加えて、水揚げ後出荷前に本発明の蓄養手法を導入することにより、高度衛生管理を含む品質を向上した生食用商品規格の標準化が可能であり、この蓄養手法を確立をもって斯界に貢献することが期待できる。   In addition to shortening the breeding period for sea surface aquaculture (single seed aquaculture) through seedling production (indoor seedling breeding) through intermediate breeding, advanced hygiene management is achieved by introducing the farming method of the present invention before landing and before shipping It is possible to standardize raw food product standards with improved quality, and it can be expected to contribute to this field by establishing this farming technique.

特に、産地を展開し各地から規格商品を集荷可能であり、地域ブランド、国産ブランドのいずれの銘柄でも統一規格の生食用商品を市場供給できるという利点がある。カキに関して至適な利用先としては、近年のオイスターバーと指称される提供場所があり、海外のオイスターバーへの商品供給も問題なく対応可能である。   In particular, there is an advantage that standard products can be collected from various locations by developing production areas, and raw food products with uniform standards can be supplied to the market for both brands of regional brands and domestic brands. The most suitable place to use oysters is a place called “Oyster Bar” in recent years, and it is possible to supply products to overseas oyster bars without any problems.
