Background technology
The breeding of prawn is mainly including embryonated egg, nauplius, shrimp seedling and into several important stages such as shrimps.Wherein, shrimp seedling
The good quality for determining into shrimp soon of quality, and the variety and quality of prawn nauplius determines the quality of shrimp seedling, therefore, seed selection
The prawn nauplius for going out premium properties is one of key technology of prawn culturing.Excellent prawn nauplius can show compared with
Good activity, the ability and phototaxis for being mainly manifested in young floating can be relatively strong, and the prawn nauplius of poor quality is then active
It is poor.
At present, in shrimp culture industry, the young of most of prawns breeds and relies primarily on wild parent, i.e., female male parent pair
The embryonated egg that shrimp produces, by forming nauplius after hatching, is then entered nauplius in larval culture pond in nursery pond
Row is cultivated.In existing prawn culturing pattern, it is uneven to there is kind activity in the nauplius hatched in larval culture pond,
Being directly entered the shrimp seedling quality cultivated after nursery pond cannot ensure, the shrimp seedling that the prawn nauplius of wherein poor activity is cultivated is held
It is vulnerable to cause of disease infringement, survival rate is low, has had a strong impact on the quality and yield of shrimp seedling, it is impossible to meet modern efficient, scale pair
The sound development of Shrimp farming.
