Abstract

The present invention discloses a new-type crob pond structure mode for breeding button crab. Said crab-breeding pond is formed from five portions of pond ridge, fixing feed-adding area, breeding channel, aquatic plant and plastic barrel, in which the breeding channel is an inverted trapezoidal shallow pond whose upper surface width is 1.00-1.20 m, bottom width is 0.4-0.5 m and depth is less than 0.5m between pond ridge and breeding channel there is a platform whose width is about 1m as feed-adding area, in the feed-adding area the plastic barrels for trapping carb are placed and the aquatic plant can be planted on the pond surface outside of breeding channel. As compared with general crab pond is can improve ecological environment of crab pond and water quality and is favorable for growth and development of button crab.

Description

Structure mode for button crab cultivation pool

Technical field:

The present invention relates to a kind of cultural method of aquatic products, particularly relate to a kind of tactic pattern that crab is cultured the pool of detaining, go into A01K61/00.

Background technology:

General culture of Chinese mitten crab mainly is meant the breed of (or claiming commodity crab) of finished product crab, but it is to culture into the button crab by juvenile crab with the developmental process of crab, will detain that crab is thrown in into the crab pool or the finished product crab of selling on the market is further cultured in the lake again.Wherein detain the breed of crab and continue to use the common crab pool always, the architectural feature on this crab pool is that furrow width, the pool are dark, mud accumulates many, there is not food platform material charging region, it is time-consuming to excavate this crab pool, the cost height, and adopt this common crab pool to culture the button crab still to have the following disadvantages: 1, because furrow width, the pool are dark, mud accumulates many, thereby sick generation of crab that pool sterilization is not thoroughly often led shone in dehydration: 2, because the pool is dark, the children crab is only cultured in ditch, the young crab concentrations of leading, both unfavorable young crab shelling growth has increased the chance that cuts one another's throat again, the inferior rate height of leading; 3, because the life habit of crab is liked adherent and burrowed, and the dark crab in the pool easily burrows, digging a hole when getting crab, it is many to catch the crab damage.The existence of the problems referred to above has seriously influenced the development and the economic benefit of button crab aquaculture, and loss occurring also is ordinary affair.Adopt the crab pool of which kind of tactic pattern to culture the button crab, the focus that has become the raiser to pay close attention to so.Though there was report in the past, disclosed 87202647 as the 1988.01.27 of Patent Office of the People's Republic of China, what it related to is a kind of special aquaculture fence, relates generally to the anti-facility of escaping in the culture of Chinese mitten crab process.Disclosed 1071043 " factory-bred river crabs and devices thereof " of 1993.04.21 and for example, it is river crab to be incorporated into indoor stereo culture in the pond at many levels and culture.And how to utilize existing farmland to carry out culture of Chinese mitten crab for vast rural area, particularly adopt the crab pool of which kind of tactic pattern to culture the button crab and become key.

Summary of the invention:

The objective of the invention is to provide a kind of novel crab pool of culturing the button crab and can solve the many weak points that exist when culture on the general crab pool again that is exclusively used in---structure mode for button crab cultivation pool (hereinafter to be referred as the button crab pool), this button crab pool is to adopt following technical scheme to implement: it is made up of the ridge, the pool, fixed feeding area district, breeding groove, water plants and five parts of Plastic Drum, wherein breeding groove is a pond groove width 1.00-1.20 rice around, bottom width 0.4-0.5 rice, the degree of depth is no more than trapezoidal (or claiming basin shape) shallow pool of 0.5 meter, as the breeding groove of button crab.Between Tang Geng (or claim ridge) and breeding groove, reserve width and be platform about 1 meter as the fixed feeding area district, and several Plastic Drums are set in the fixed feeding area district use for getting the button crab.Plantation is based on the water plants of water peanut, water horse spot grass on the pool face outside the breeding groove, and the area coverage of water plants reaches more than 3/4ths of pool face.Culture for large tracts of land button crab, having in the middle of at first pool face being divided into the pulk on the little ridge to carry out lattice puts in a suitable place to breed, every lattice area is controlled at 0.8-1 mu and is advisable, so that ingest and the diseases prevention management, makes getting final product by the mode on the above-mentioned button crab pool as for the tactic pattern of each little lattice.It is same or similar with the general crab pool that the button crab pool anti-escapes facility.The button crab pool that makes according to technique scheme meets the good ecotope of cultivating the growth of button crab, compare with the method that the button crab is cultured on the dark pool of general employing and to have following advantage: 1, save the excavation crab pool and dig a hole and get the artificial of crab, because shallow pool cultivated crabs can't burrow, major part is crept in the water plants, only need (to refer to water plants) in the grass when getting crab and turn over, get in the bucket, inferior rate is low; 2, the water plants of plantation with self-sow ability is better than artificial input forage, and its reason is: the one, for young crab provides sufficient vegetal bait, reduce feed cost; The 2nd, a large amount of organic substances that absorb young crab metabolism generation purify water, and increase dissolved oxygen in water by photosynthesis in the aquatic plants growth process; The 3rd, the environment for young crab provides peace and quiet to perch and shell reduces the chance that cuts one another's throat, and effectively defends the invasion and attack of harmful animal: the 4th, can regulate water temperature, can hide the cloud cooling summer, reduce the temperature difference, reduce the sexual stimulus of make-up crab, crab crept into water mostly and played thermal effect from the grass winter.3, effectively reduce disease and take place, the disease of river crab is the formidable enemy who cultures, dark pool cultivation density height, water quality worsens easily, concentrate in flakes on the raiser crab pool, and infection chance is many mutually, adopt shallow pool lattice to put in a suitable place to breed after, mud is few, be convenient to scrubbing, pool dehydration is tanned by the sun, and the soup sterilization is more thorough, the self-sow of water plants has improved crab pool environment and water quality in addition, effectively prevents the sick generation of crab etc.

Fig. 2, button crab are cultured pool A-A profile.

Embodiment:

Structure mode for button crab cultivation pool such as Fig. 1, shown in Figure 2, wherein Fig. 1 is the tactic pattern that each little lattice button crab is cultured the pool, its area is advisable with 0.8-1 mu, the tactic pattern that concrete each little lattice button crab is cultured the pool is such: it is by the ridge, the pool 1, fixed feeding area district 2, breeding groove 3,5 five parts of water plants 4 and Plastic Drum are formed, wherein breeding groove is a pond groove width a=1.00-1.20 rice around, bottom width b=0.4-0.5 rice, degree of depth h is no more than 0.5 meter inverse ladder-shaped hollow pond, between the ridge, the pool 1 and breeding groove 3, reserve width and be platform about 1 meter as fixed feeding area district 2, and several Plastic Drums 5 are set in the fixed feeding area district, plantation is with water peanut on the pool face outside the breeding groove, water horse spot grass is main water plants 4, and the area coverage of water plants reaches more than 3/4ths of pool face.Spacing between the general ridge, the pool 1 and the fixed feeding area district 2 is that the ridge, pool height C is about 0.3 meter.Culture for large tracts of land button crab, at first pool face is divided into the little lattice about 0.8-1 mu, excavate by above-mentioned pattern then.
