Description

本発明はマナマコの養殖技術分野に属し、特に人工ナマコリーフを利用したマナマコの海底養殖方法に関する。 The present invention belongs to the field of aquaculture technology for Apostichopus japonicus, and particularly relates to a method for aquaculture of Apostichopus japonicus using an artificial Apostichopus japonicus leaf.

マナマコの底撒き増殖は、健康的で生態学的な養殖模式であり、即ち、適切な海域に、一定規格のマナマコ種苗を一定の密度で投入し、それが海底で自然に成長し、増殖し続けるようにすることである。上記適切な海域は2つの種類に分けられ、1つは岩礁または砂石底質の海域であり、ナマコ種苗を直接放流することができる。もう一つは、人工ナマコリーフを投入して、海底の生息地再構築した岩礁、砂石、硬い砂などの底質を含む海域である。上記人工ナマコリーフには、現在、様々な種類があり、材料から主に石材、セメント部材、コンクリート部材、廃漁船と乗り物及びカキ殻などに分けられ、形から主に丸管、立方体、直方体、三角柱、はしご形などに分けられる。人工ナマコリーフの合理的設計と科学的投入は、マナマコを誘惑して集め、マナマコのために遮蔽物を提供する役割を果たすだけでなく、海底の生態学的環境を改善し、生物資源の量を増やして、マナマコが摂食して成長するための餌を提供すること、魚やエビなど水産物を集めることで産出する利益も増加させる。 Bottom-sowing proliferation of Apostichopus japonicus is a healthy and ecological aquaculture model, that is, a certain standard of Apostichopus japonicus seedlings is put into a suitable sea area at a certain density, and it naturally grows and proliferates on the seabed. To continue. The above suitable sea areas can be divided into two types, one is a reef or sandy bottom sedimentary area, and sea cucumber seedlings can be released directly. The other is the sea area containing sediments such as reefs, sandstones, and hard sand that have been reconstructed from the seafloor habitat by introducing artificial sea cucumber leaves. Currently, there are various types of artificial sea cucumber leaves, which are mainly divided into stones, cement members, concrete members, abandoned fishing boats and vehicles, oyster shells, etc., and mainly round pipes, cubes, rectangular parallelepipeds, etc. It can be divided into triangular prisms and ladder shapes. The rational design and scientific input of artificial sea cucumber not only serves to seduce and collect sea cucumbers and provide a shield for sea cucumbers, but also improve the ecological environment of the seabed and the amount of biological resources. To provide food for sea cucumbers to feed and grow, and to increase the profits produced by collecting marine products such as fish and shrimp.

現在、人工ナマコリーフを投入して、浅瀬における底撒き増殖によるマナマコの生産は主に以下の問題点がある。種苗の放流密度及び養殖の単収が低い。現在、よく使われる石及び人工的に設計されたナマコリーフ部材は海流に対するブロックが生じやすいため、投入する密度は大きくできず、多くが海域面積の３０％を超えないため、マナマコが利用できる付着面積が減少し、種苗の放流密度が低くなり（３～７尾／平方メートルを超えないのが一般的である）、育成後の単収は多くが５０～７０ｋｇ／ムー（約７５～１０５Kg／平方キロメートル） である。生残率が低く、従来のナマコリーフ（石やセメントの部材など）及びその設置方法は多くがマナマコの生息地として用いるが、付着及び遮蔽にする面積が小さく、餌を十分に提供することもできないため、底撒き増殖するマナマコの生残率が低く、とくに、１２０尾／斤（２４０尾／Kg）以下のナマコ種苗を放流した場合、生残率は５０％も満たない。マナマコの成長が遅く、育成期間が長い。マナマコの底撒き増殖は手動で補充する餌を与えることができないため、また、従来のナマコリーフ(石、セメント部材など)及びその設置方法は、水交換に不利であり、水の中の栄養物質や生物餌料資源の繁殖が遅く、量が少ないため、マナマコの生育が遅く、育成期間が長くなる。回収率が低い。従来の石などのナマコリーフ及びその設置方法は不規則な形状やナマコを集まる効果が悪いため、マナマコの設置が割と分散的で、ダイバーの漁獲が困難になる。集魚効果が悪い。従来のナマコリーフは機能が単一で、設置方法においても海流を導く効果及び集魚効果が得られず、または効果が悪く、魚やエビなどの他の副産物の漁獲が少なく、利益が低く、利益率は３０％～４０％にあるのが一般的である。 At present, the production of sea cucumber by introducing artificial sea cucumber leaf and sprinkling it in shallow water has the following problems. The stocking density of seedlings and the yield of aquaculture are low. Currently, commonly used stones and artificially designed sea cucumber leaf members are prone to block against ocean currents, so the density of injection cannot be increased, and many do not exceed 30% of the sea area, so sea cucumber can be used for adhesion. The area is reduced, the discharge density of seedlings is low (generally not exceeding 3 to 7 fish / square meter), and the yield after growing is mostly 50 to 70 kg / mu (about 75 to 105 kg / square kilometer). ). The survival rate is low, and conventional sea cucumber leaves (stones, cement members, etc.) and their installation methods are often used as habitats for sea cucumbers, but the area to be attached and shielded is small, and sufficient food can be provided. Because it cannot be done, the survival rate of sea cucumbers that grow on the bottom is low, and in particular, when the sea cucumber seedlings of 120 fish / loaf (240 fish / Kg) or less are released, the survival rate is less than 50%. Manamako grows slowly and has a long growing period. Since the bottom-spreading growth of sea cucumber cannot be fed manually to be replenished, conventional sea cucumber leaves (stones, cement members, etc.) and their installation methods are disadvantageous for water exchange and nutrients in water. And because the breeding of biological feed resources is slow and the amount is small, the growth of sea cucumber is slow and the growing period is long. The recovery rate is low. Since the conventional sea cucumber leaf such as stone and its installation method have an irregular shape and the effect of collecting sea cucumber is poor, the installation of sea cucumber is relatively dispersed and it becomes difficult for divers to catch. The effect of collecting fish is poor. The conventional sea cucumber leaf has a single function, and even if it is installed, the effect of guiding the ocean current and the effect of collecting fish are not obtained or the effect is poor, the catch of other by-products such as fish and shrimp is small, the profit is low, and the rate of return is low. Is generally in the range of 30% to 40%.

そこで、本発明の目的は、人工ナマコリーフ及び、上記施設を利用して海底でマナマコを養殖する方法を提供することである。上記人工ナマコリーフ及び方法は適切な種苗を放流する密度を大幅に向上させ、増殖生残率を向上させ、育成期間を短縮し、回収率及び他の漁獲物資源の収穫量を向上させることができる。 Therefore, an object of the present invention is to provide an artificial sea cucumber leaf and a method for culturing sea cucumber on the seabed using the above facilities. The artificial sea cucumber leaves and methods can significantly improve the density of stocking appropriate seedlings, improve the growth survival rate, shorten the growing period, improve the recovery rate and the yield of other catch resources. can.

Guarantee the circulation of seawater and minimize the impact on the ecological environment.

さらに、上記人工ナマコリーフの表面が粗い面であるので、マナマコが付着するのに有利である。 Further, since the surface of the artificial sea cucumber leaf is a rough surface, it is advantageous for the sea cucumber to adhere.

本発明によって提供される上記人工ナマコリーフを利用したマナマコの海底養殖方法は、上記人工ナマコリーフによりナマコリーフ施設グループが構成し、上記ナマコリーフ施設グループを「彡」の形に並べて、上記ナマコリーフ施設グループの設置が海水の流れを妨げないようにして、死水塊の形成を避け、且つナマコリーフの動きを効果的に防ぐことができる。「彡」の形に並べると、バッファを残して、海水の循環を形成するので、マナマコの餌になる栄養物質である海底有機物など交換するのに有利である。人工ナマコリーフの上の円形貫通孔は海水の流速を弱めることができ、底生藻類の繁殖とマナマコが移動して摂食するのに資し、それによってナマコの成長を促進し、他の漁獲物資源の収穫も増やすことができる。 In the sea cucumber seabed cultivation method using the artificial sea cucumber leaf provided by the present invention, the sea cucumber leaf facility group is composed of the artificial sea cucumber leaf, and the sea cucumber facility group is arranged in the shape of "彡" to form the sea cucumber leaf. The establishment of facility groups can prevent the flow of seawater, avoid the formation of dead water lumps, and effectively prevent the movement of sea cucumber reefs. When arranged in the shape of "彡", it leaves a buffer and forms a circulation of seawater, which is advantageous for exchanging marine organic matter, which is a nutritional substance that feeds manamako. Circular through-holes above artificial sea cucumber reefs can slow the flow of seawater, helping to breed benthic algae and allow sea cucumbers to move and feed, thereby promoting sea cucumber growth and other catches. The harvest of resources can also be increased.

本実施形態によれば、本発明のマナマコの海底養殖方法は、種苗の適切な放流密度を大幅に向上させることができ、１５０尾の種苗である場合、従来の３～５尾／平方メートルから、８～１３尾／平方メートルに 向上させることができる。 According to the present embodiment, the method of submarine aquaculture of Apostichopus japonicus of the present invention can significantly improve the appropriate release density of seedlings, and in the case of 150 seedlings, the conventional method of 3 to 5 fish / square meter can be used. It can be improved to 8 to 13 fish / square meter.

本発明の方法によれば、放流するナマコ種苗の規格下限を低下させ、ナマコ種苗の生残率を向上させることができ、従来方法によれば、１２０尾／斤（２４０尾／Kg）以下のナマコ種苗の生残率は５０％より低いことに対し、本発明の方法によれば３０尾／斤（６０尾／Kg）のナマコ種苗を投入する場合、ナマコ種苗の生残率は９８％～１００％に達し、５０尾／斤（１００尾／Kg）の場合９４％～９６％に達し、１００尾／斤（２００尾／Kg）の場合８９％～９２％に達し、１５０尾／斤（３００尾／Kg）の場合８４％～８７％に達し、５００尾／斤（１０００尾／Kg）の場合７６％に達することができる。 According to the method of the present invention, the lower limit of the standard of the released Namako seedlings can be lowered and the survival rate of the Namako seedlings can be improved. According to the conventional method, 120 loaves / loaf (240 loaves / Kg) or less. The survival rate of Namako seedlings is lower than 50%, whereas according to the method of the present invention, when 30 loaves / loaf (60 loaves / Kg) of Namako seedlings are introduced, the survival rate of Namako seedlings is 98% or more. It reaches 100%, reaches 94% to 96% in the case of 50 loaves / loaf (100 loaves / kg), reaches 89% to 92% in the case of 100 loaves / loaf (200 loaves / kg), and reaches 150 loaves / loaf (150 loaves / loaf). In the case of 300 fish / kg), it can reach 84% to 87%, and in the case of 500 fish / loaf (1000 fish / Kg), it can reach 76%.

本発明の方法は、ナマコ種苗の成長速度を上げることができ、異なる規格グループ別のナマコ種苗の成長率はいずれも改善されている。 The method of the present invention can increase the growth rate of sea cucumber seedlings, and the growth rates of sea cucumber seedlings in different standard groups are all improved.

本発明の方法はまた回収率を向上させることができ、従来の方法の回収率は約４０％であのに対し、本発明の方法は４５．８％～５８．２％に達することができる。 The method of the present invention can also improve the recovery rate, and the recovery rate of the conventional method is about 40%, whereas the method of the present invention can reach 45.8% to 58.2%.

本発明の方法はまた、他の漁獲資源の量を１５％以上増加させて、経済的利益を増加させることができる。 The method of the present invention can also increase the amount of other catch resources by 15% or more to increase economic benefits.

本発明は人工ナマコリーフを提供し、上記人工ナマコリーフは市販のコンクリート材料からなる第一のリーフボート（１）及び第二のリーフボート（２）を含み、上記第一のリーフボート（１）と第二のリーフボート（２）は逆「Ｖ」形に接続され、上記第一リーフボート（１）及び第二リーフボート（２）には貫通孔が均一に設置され、上記第一リーフボート（１）と第二リーフボート（２）は一体成形である。本発明における人工ナマコリーフの構造は図１に示し、そのうち１が第一リーフボートであり、２が第二リーフボートであり、３が円形貫通孔である。 The present invention provides an artificial sea cucumber leaf, wherein the artificial sea cucumber leaf includes a first leaf boat (1) and a second leaf boat (2) made of a commercially available concrete material, and the first leaf boat (1). And the second leaf boat (2) are connected in an inverted "V" shape, and the first leaf boat (1) and the second leaf boat (2) are uniformly provided with through holes, and the first leaf boat (1) and the second leaf boat (2) are uniformly provided with through holes. (1) and the second leaf boat (2) are integrally molded. The structure of the artificial sea cucumber leaf in the present invention is shown in FIG. 1, of which 1 is a first leaf boat, 2 is a second leaf boat, and 3 is a circular through hole.

本発明において、上記人工ナマコリーフの第一のリーフボート（１）と第二のリーフボート（２）は逆「Ｖ」字形に接続され、上記第一リーフボート（１）と第二リーフボート（２）の接続角の内角は５０～７０°が好ましく、５５～６５°がより好ましく、６０°が最も好ましい。上記第一リーフボート（１）と第二リーフボート（２）との接続角の内角が上記角度範囲内にあれば、人工ナマコリーフの第一リーフボート及び第二リーフボートと海底の平面とが構造が安定した正三角形またはほぼ正三角形を構成し、リーフ部材全体が海底にしっかり配置されるのに有利であり、海流に移動されにくくなる。内角が小さすぎると、部材の重心が高くなり、且つ海流の推進力を受ける面積が大きくなり、リーフ部材の安定性に不利であると同時に、二つのリーフボートの斜面が急になるので、ナマコなどの生物が付着するのに不利である。内角が大き過ぎると、人工ナマコリーフの第一リーフボート及び第二リーフボートと海底平面の角度が小さくなり、リーフ部材全体の付着できる面積が減る。 In the present invention, the first leaf boat (1) and the second leaf boat (2) of the artificial sea cucumber leaf are connected in an inverted "V" shape, and the first leaf boat (1) and the second leaf boat (2) The internal angle of the connection angle of 2) is preferably 50 to 70 °, more preferably 55 to 65 °, and most preferably 60 °. If the internal angle of the connection angle between the first reef boat (1) and the second reef boat (2) is within the above angle range, the first reef boat and the second reef boat of the artificial Namako reef and the plane of the seabed can be connected. It forms an equilateral triangle or a nearly equilateral triangle with a stable structure, which is advantageous for the entire reef member to be firmly placed on the seabed and is difficult to be moved to the sea current. If the internal angle is too small, the center of gravity of the member will be high and the area that receives the propulsive force of the ocean current will be large, which is disadvantageous to the stability of the leaf member and at the same time, the slopes of the two leaf boats will be steep. It is disadvantageous for organisms such as. If the internal angle is too large, the angle between the first and second leaf boats of the artificial sea cucumber leaf and the seafloor plane becomes small, and the area to which the entire leaf member can adhere decreases.

本発明における第一リーフボート（１）及び第二リーフボート（２）に均一に貫通孔が設置され、本発明における、上記第一リーフボート及び第二リーフボート（２）の厚さは０．２５～０．３５ｍが好ましく、０．２８～０．３２ｍがより好ましく、０．３ｍが最も好ましい。上記第一リーフボート（１）及び第二リーフボート（２）の長さは１．５ｍ～２．５ｍが好ましく、１．７ｍ～２．３ｍがより好ましく、２．０ｍが最も好ましい。上記第一リーフボート（１）及び第二リーフボート（２）の幅は１．５ｍ～２．５ｍが好ましく、１．７～２．３ｍがより好ましく、２．０ｍが最も好ましい。本発明において、上記貫通孔は円形貫通孔が好ましく、四角形や六角形などの多角形であってもよく、上記円形の直径は０．２～０．４ｍが好ましく、０．２５～０．３５ｍがより好ましく、０．３ｍが最も好ましい。上記貫通孔が多角形である場合、上記貫通孔の多角形の対角線の長さは０．２～０．４ｍが好ましく、０．２５～０．３５ｍがより好ましく、０．３ｍが最も好ましい。本発明において、好ましくは上記人工ナマコリーフの第一リーフボート（１）及び第二リーフボート（２）の自由端側の０．４～０．６ｍに円形貫通孔が設置されなく、より好ましくは自由端側０．５ｍに円形貫通孔が設置されない。これは、人工ナマコリーフは海底に投入されたあと、必ずいくらか沈下するので、円形貫通孔が設置されても海流を妨げることを防止する役割を果たせず、円形貫通孔が設置されないことは、上記人工ナマコリーフが海底での安定性を増加し、移動を減少させる。 Through holes are uniformly provided in the first leaf boat (1) and the second leaf boat (2) in the present invention, and the thickness of the first leaf boat and the second leaf boat (2) in the present invention is 0. It is preferably 25 to 0.35 m, more preferably 0.28 to 0.32 m, and most preferably 0.3 m. The lengths of the first leaf boat (1) and the second leaf boat (2) are preferably 1.5 m to 2.5 m, more preferably 1.7 m to 2.3 m, and most preferably 2.0 m. The width of the first leaf boat (1) and the second leaf boat (2) is preferably 1.5 m to 2.5 m, more preferably 1.7 to 2.3 m, and most preferably 2.0 m. In the present invention, the through hole is preferably a circular through hole, may be a polygon such as a quadrangle or a hexagon, and the diameter of the circular shape is preferably 0.2 to 0.4 m, preferably 0.25 to 0.35 m. Is more preferable, and 0.3 m is most preferable. When the through hole is a polygon, the diagonal length of the polygon of the through hole is preferably 0.2 to 0.4 m, more preferably 0.25 to 0.35 m, and most preferably 0.3 m. In the present invention, it is preferable that no circular through hole is provided at 0.4 to 0.6 m on the free end side of the first leaf boat (1) and the second leaf boat (2) of the artificial sea cucumber leaf, and more preferably. No circular through hole is installed 0.5 m on the free end side.
