Problems solved by technology

[0003] At present, my country's domestic net-cultured purple-red seedlings mainly rely on catching natural fry. Because the naturally caught fry are small (generally about 2 cm in length), the survival rate of directly putting them into net cages is low (the general survival rate is 20-20 cm). 30% or even lower)

Abstract

The invention provides a method for indoor artificial breeding of lutjanus argentimaculatus. The method includes steps of indoor cement pond setting and fish fry breeding. Fish fry breeding in different areas is realized through three stages, and in each area, salinity, water temperature and pH value regulation is carried out, and different baits and microbial preparations are applied. By scientific matching of the baits, the survival rate of hatched fish fry reaches 98%, the average body length is 35mm, and low fat content, high fish body quality, fleshiness and body surface smoothness are achieved while a short harvesting period and high economic benefits are achieved as well.

Description

technical field [0001] The invention relates to the technical field of aquatic cultivation, in particular to an indoor artificial seedling raising method of purple snapper. Background technique [0002] Purple snapper, scientific name: Lutjanus argentimaculatus, common name red squid, belongs to Perciformes, suborder Perciformes, Snapperidae, genus Snapper. Warm-water fish, distributed in the Indian Ocean and the South Pacific Ocean, and it is produced in the South China Sea and the southern part of the Taiwan Strait in China. Purple snapper is a high-quality edible fish with large body and delicious meat. It is an important marine fish in the coastal provinces of southern my country. The fish meat is delicious and has high nutritional value, and is very popular among consumers. The purple snapper grows fast, has a short breeding cycle, and can adapt to a wide range of temperature and salinity. It is an important species in coastal ponds and cages in southern my country. ...
