Description

Net cage culture water bloom fry system

Technical Field

The utility model relates to a, concretely relates to net cage culture water flower fry system.

Background

The fry of water bloom is an important stage of early development of fish, and whether the cultivation is successful or not is very important for the cultivation yield of the year. The water flower fry is weak and easy to die due to poor adaptability to the environment. In this case, the management personnel expend a lot of time and energy to patrol the pond and pay careful attention to the activity of the fry to ensure the survival of the fry.

The sexual maturity time of different fishes is different, the time for the offspring to begin to develop is different, if the fishes are mixedly cultured, the fry with late development time can not obtain sufficient nutrition, and in addition, the feeding capability of the fry of the water bloom is weak, and the swimming capability is poor, so that the traditional aquaculture industry carries out special pond feeding and thorough pond cleaning on the fry of the water bloom so as to prevent the situations of snatching, killing natural enemies and the like. The special pond feeding is the key for ensuring high survival rate and high growth speed of the fry. However, with the ten years of inhibition of fish development in Yangtze river, many natural water bodies cannot be used for aquaculture, in addition, the policy of farmland management is tightened, agricultural land cannot be used for pond-digging fish culture, and the expansion of aquaculture area is further limited. In the presence of increasing demand for aquatic products, it is imperative to ensure that the production of commercial fish is continuously increased while maintaining the continuous growth of fry rearing scale. Thus improving the current pond utilization is essential to ensure sustainable development of the aquaculture industry.

Therefore, cage culture is gradually developed in recent years, but cage culture of the fries of the water flowers needs to be matched with an aerator to ensure the dissolved oxygen in water, and the cost is higher if oxygen is supplied to a large number of cages due to the limitation of the power of the aerator. In addition, the net cage culture water bloom has dense meshes and large resistance to water body exchange with the outside of the net cage, so that the water body in the net cage is easy to deteriorate, and the fry of the water bloom is dead.
