Artificial breeding method for parapenaeopsis hardwickii

Abstract

Disclosed is an artificial breeding method for parapenaeopsis hardwickii. A breeding pond is a circular or square cement pond, the area of the breeding pond is 12-20m<2>, the depth of the breeding pond is 0.7-1.0m, fine water circulation and pollution discharge functions are required, water is transparent, clear and free from harmful heavy metal ions, water with the depth of 70cm-100cm enters the parapenaeopsis hardwickii pond for the first time, the water is disinfected with 0.3mg / L of dibromohydantoin, individuals with plump gonads, strong bodies, no diseases and tawny or breen ovaries are selected as parent shrimps, after the sea parent shrimps are transported for a long distance, shrimp baskets are immediately immerged into the parent shrimp breeding pond, baits for opossum shrimps at a larva stage are yolks, compound feed (prawn crackers, Cheyuan and BP) and rotifers, the rotifers are generally fed twice a day, and the breeding water is filtered by a 100-mesh dilly bag.

Description

technical field [0001] The invention relates to an aquaculture method, in particular to a method for artificial breeding of Penaeus harbachii. Background technique [0002] Hardwicki imitation shrimp (Parapenaeopsis hardwickii (Miers)) belongs to decapod order, shrimp family, shrimp family, and imitation shrimp genus (commonly known as slippery shrimp, choking shrimp). According to 5Zhejiang Fauna 6 (Crustaceans), the shrimp is offshore, a medium-sized shrimp (the author surveyed the body up to 12 cm in length), grows within 70 m of the shore, and can inhabit various geological seabeds , widely distributed in Zhejiang sea area in summer, mostly concentrated in coastal waters within 30 m. Distributed in the southern part of the Yellow Sea in my country, and abroad in Pakistan, India, Singapore, Malaysia and other countries. The shrimp has a high yield and good meat quality. It is used for fresh food (the taste of the shrimp is particularly delicious) and made into sea rice....

AI Technical Summary

Problems solved by technology

[0004] However, due to the early development and utilization of the Imitation prawn resources in the northern part of the East China Sea and the lack of scientific management, the amount of resources of this shrimp has decreased significantly in the past 10 years. benefit decline

At present, the natural resources of the imitation prawns can no longer meet the needs of the market. Carrying out the artificial breeding of the imitation prawns, carrying out release proliferation and artificial breeding are effective ways to solve the problem

There are few domestic researches on the breeding of Imitation Penaeus harveyensis
