Abstract
The utility model discloses an ecological prevention and control system for excessive microalgae in prawn nursery or breeding. The ecological prevention and control system comprises a net box, fairy shrimps and an oxygenation device, wherein the fairy shrimps are arranged in the net box. According to the technical scheme, the excessive microalgae and small suspension bait which cannot be easily fed by prawns in a prawn nursery pond or a breeding pond can be controlled, and meanwhile the grown fairy shrimps are the optimum bait for the prawns. The water environment in prawn seed nursery or breeding can be controlled to be good, prawn diseases can be reduced, and meanwhile cost including bait cost and drug use cost can be reduced. The ecological prevention and control system for excessive microalgae in prawn nursery or breeding is simple in structure, low in cost, convenient to install, high in practicability, and particularly suitable for prawn ponds where the microalgae are bred excessively fast in the prawn breeding process.
Description
Technical field
The utility model belongs to aquaculture system technical field, relates to the too much ecological prevention and control system of micro-algae in a kind of prawn seed-rearing or cultivation.
Background technology
At present,, there is series of problems in prawn seed-rearing and breeding process in flourish along with shrimp culture industry, and wherein basic reason is water quality deterioration, and in water body the too much or residual bait of micro-algae to leach Yu Shuizhong be the key factor that causes water quality deterioration.
In water body, micro-algae is too much, even forms wawter bloom, and transparency is low, can cause that micro-algae is aging, mortality, forms noxious material, and the cultivation of prawn is caused to very large impact.Therefore how controlling the amount of micro-algae in water body is urgent problem of aquaculture, at present prawn seed-rearing and cultivation in for water body in micro-algae very few, the problem of how to breed has the method for inoculation, getting fat, successful, but too much for micro-algae in water body, how to control the growth of micro-algae, the amount that how to keep micro-algae in water body is in but not good method of the problem of certain limit.
Feed is the material base of prawn growth, and the feed choosing is one of successful key factor of healthy aquaculture.Prawn belongs to and embraces a feeding habits animal, require for the particle diameter of feed quite strict, but no matter any feed, in the process of throwing something and feeding, all can some decompose to suspend or leach Yu Shuizhong and form residual bait, prawn cannot ingest.Residual bait is main organic pollution source of shrimp culture pond, and residual bait is too much, not only affects feed coefficient, increases prawn culturing cost, and the decomposition of residual bait need to consume a large amount of dissolved oxygens, produces ammonia nitrogen, nitrite simultaneously.Rationally throw something and feed at present and can at utmost reduce the amount of residual bait, but but cannot tackle the problem at its root.
Throwing something and feeding of live bait can meet the nutritional need of prawn growth, can reduce the harmful effect of bait to water environment simultaneously, the live bait of throwing something and feeding in right amount in prawn cultivating process can effectively improve survival rate, improve growth rate, fairy shrimp is the suitableeest live bait of prawn, and fairy shrimp price is high now, uses the considerably less of fairy shrimp in prawn culturing process, if throw something and feed and can reduce bait cost but fairy shrimp can be formed after adult, can meet prawn growth simultaneously required.
Utility model content
In order to overcome defect of the prior art, solve the problems of the technologies described above, the utility model provides the too much ecological prevention and control system of micro-algae in a kind of prawn seed-rearing or cultivation, the small suspension bait that the utility model can cannot feed into micro-algae too much in prawn nursery pond or cultivating pool and prawn is controlled, fairy shrimp after simultaneously growing up to is also the suitableeest bait of prawn, can control good water environment in shrimp seed rearing or cultivation, reduce the generation of disease of prawn, can also reduce cost, comprise bait cost and drug cost simultaneously.The utility model is simple in structure, cost is low, and easy for installation, practical, is specially adapted to occur in prawn culturing process the shrimp pool of too much micro-algae.
Its technical scheme is as follows:
The too much ecological prevention and control system of micro-algae in prawn seed-rearing or cultivation, comprises net cage, fairy shrimp and oxygen-increasing device, and described fairy shrimp is placed in net cage and cultivates.
Further preferably, described net cage mesh is 100 orders.
Further preferably, described fairy shrimp size >100 object mesh.
Further preferably, described net cage length, width and height are respectively: 1.5m, 1.2m, 2m.
Further preferably, described net cage length, width and height are respectively: 4m, 3m, 1.5m.
Further preferably, described oxygen-increasing device is waterwheel aerator.
Further preferably, the distance of described waterwheel aerator and net cage is 10m.
Further preferably, the breeding density of described fairy shrimp is 5/ml.
Further preferably, the breeding density of described fairy shrimp is 6/ml.
Further preferably, described oxygen-increasing device is gas stone.
The beneficial effects of the utility model:
1, the fairy shrimp that the utility model adopts can effectively filter too much micro-algae in food prawn nursery pond or culturing pool, not only the quantity of micro-algae has been lived in prevention and control, micro-algae effectively can also be used, avoid micro-algae too much to form wawter bloom, aging, mortality, the situation that forms noxious material, reaches the object turning waste into wealth.
2, the fairy shrimp that the utility model adopts can effectively filter dissolves in food prawn nursery pond or culturing pool or is suspended in the residual bait in water body, avoid the decomposition of residual bait need to consume a large amount of dissolved oxygens, produce ammonia nitrogen, nitrite simultaneously, reach the object purifying water.
3, the net cage mesh that the utility model adopts is 100 orders, can avoid fairy shrimp nauplius to pass and enter in prawn nursery pond or culturing pool from mesh as far as possible, can allow micro-algae and small suspension bait enter smoothly in net cage, the micro-algae existing in more effective control water body and residual bait simultaneously.
