Abstract
The utility model relates to an aquatic cultivation pot, in particular to young crab growth apparatus that is suitable for megalops of ocean crabs and juvenile crab at a first to third stage. The utility model provides a young crab growth pot that improves the survival rate of the young crab and is convenient for the sales of the juvenile crab, which has a screen frame, a floating body and a netting; the floating body is arranged on the screen frame, the upper mouth of the netting is communicated to the screen frame, and the netting has twenty to forty screen meshes, which reduces the labor of the operator, avoids the losses due to inappropriate operation, has simple and light structure, is capable of using repeatedly and is easy to be promoted for application in the aquatic cultivation industry.
Description
Technical field
The utility model relates to a kind of aquiculture net cage, especially relates to a kind of abnormal device of juvenile crab that is applicable to ocean crab class megalops larva and first to third phase son crab.
Background technology
Mud crab and swimming crab are the important mariculture crab classes of China.When artificial breeding proceeds to juvenile crab (megalops larva and the young crab) stage, the life style of the young is converted into the end and dwells by swimming, and the demand of existence area is strengthened suddenly; In addition,, very high lethality often occurs, seriously cut down the juvenile crab survival rate in this stage because juvenile crab has internecine life habit.How to increase the existence area of juvenile crab in the nursery pond, become the key of dealing with problems.In addition, the juvenile crab that ocean crab class is sold is generally young crab, according to method in common now, must put dried larval rearing water, could clean out young crab fully, and this process not only expends time in, and can damage the health of young crab.Therefore, the pool technology that goes out of young crab is needed badly and is improved.
Summary of the invention
The utility model is intended to go out the shortcoming that exists in the pool technology at existing juvenile crab, provides a kind of raising juvenile crab abnormal survival rate, the abnormal net cage of the juvenile crab that convenient young crab is sold.
The utility model is provided with screen frame, buoyancy aid and etting, and buoyancy aid is located on the screen frame, and the upper opening of etting is connected on the screen frame, and etting is 20～40 orders.
Screen frames such as that described screen frame can be is square, triangle, circle or ellipse, screen frame can be tubulose screen frame or shaft-like screen frame, and screen frame can be plastic tube screen frame, bamboo trunk screen frame, metal tube screen frame or rod screen frame etc.Described buoyancy aid can be floating block, ball float, fly rod etc.Described etting can be bolting silk etting, nylon etting or mosquito netting etting etc.
Described screen frame is preferably the rectangle screen frame, and its length and width preferably is respectively 100～200,50～100cm.Buoyancy aid is established 4, is located at respectively on 4 frames of rectangle screen frame.The length of etting preferably is respectively 100～200,50～100,50～100cm.
When the utility model places nursery pond, can keep floating and making screen frame exceed the water surface.Because etting made by 20～40 purpose bolting silk nets, nylon wire etc., so the food organisms net cage of can freely coming in and going out, and juvenile crab can not escape away.During use, abnormal net cage is put into nursery pond, again megalops larva is transferred in the net cage.The existence of etting has increased juvenile crab greatly climbs and grabs the area that adheres to, and has reduced cutting one another's throats, and has improved distortion ratio and survival rate.Compare with the existing methods such as net sheet, oyster shell of hanging that adopt, the utility model has reduced the amount of labour of personnel operation significantly, the loss of having avoided misoperation to cause.When selling juvenile crab, can take out several abnormal net cages and get final product according to client's demand, the process of emerging is very convenient.Of the present utility model simple for structure light and handy, and can be repeatedly used, be easy in culture fishery, apply.
