High-effective intensive culture technology for introduced parent shrimp

Abstract

The present invention belongs to aquaculture technology, especially is to introduce high-effective living-protective intensive culture technology for parent shrimp. The said technology includes the following steps: washing and disinfecting culture ponds and workshop, supplying water for culture ponds, adjusting temperature and salts, adjusting light intensity, disinfecting culture ponds water and parent shrimp, putting parent shrimps into culture ponds, management. Introduce high-effective living-protective intensive culture technology of the present invention is through physical, chemical, biological, pharmaceutical as well as various measures combined with the integrated technology method, it avoids the urgency of the new environment effectively for the introduction of parent shrimps, prevents diseases, improves the survival rate.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, in particular to a method for intensive cultivation of introduced broodstock shrimp. Background technique [0002] The prior art is generally between 30-70% to the survival rate of introducing broodstock, but also has less than 10%, even lower. The main reason for the low survival rate is: the broodstock shrimp originally lived in a pond with a depth of more than 1 meter. If they are cultured in broodstock breeding ponds with a water depth of about 50 centimeters, the factors of their living environment have changed, which may easily cause stress on the living environment of the broodstock. Easy to go wrong. According to the situation of breeding broodstock in many breeding farms in recent years, there are as few as 500 pairs of broodstock imported from the United States, and as many as 4,000 pairs. Up to 50%, some of them all died within 1-2 months, and the economic loss was very large. ...

AI Technical Summary

Problems solved by technology

There are several technical shortcomings in the low survival rate of the existing technology: (1) when the broodstock was purchased and entered into the broodstock cultivation pond, the light intensity of the cultivation pond workshop was not adjusted to an appropriate level, which caused the broodstock shrimp to be stressed to the living environment. , prone to weaken the immune system and get sick

(2) When the broodstock enters the breeding pond, effective drugs are not put into the disinfection of the water body and the care of the broodstock body, so that the stress response caused by the change of the living environment, the injury of the broodstock transportation and other reasons cannot be effectively resolved. , while infecting the disease

(3) After the parent shrimps were introduced into the breeding pond, they were not fed with palatable and easily digestible feed, which resulted in the parent shrimps not being full and eating poorly, empty stomach for a long time, weak constitution and death due to disease
