Artificial sea bass breeding method suitable for river mouth areas

Abstract

The invention provides an artificial sea bass breeding method suitable for river mouth areas. According to the method, the artificial sea bass breeding suitable for the river mouth areas is realized by virtue of the steps of parent sea bass selection and domestication, parent fish reproduction, fertilized ovum incubation, indoor fry cultivation, outdoor fry cultivation, fry screening and fry taking-out. The method is used for solving the key problems such as parent sea bass selection standards and domestication environment condition requirements, artificial parent fish ripening and spawning induction methods, artificial fertilization method, fertilized ovum incubation condition requirements, fry cultivation condition requirements, indoor and outdoor fry cultivation and bait transformation; the survival rate of sea bass fry stocking and the breeding efficiency can be remarkably improved; in short, the method is significant for the healthy development of the sea bass breeding industry in the river mouth areas of Pearl River Delta.

Description

Technical field [0001] The invention relates to the field of artificial breeding of sea bass, in particular to a sea bass artificial breeding method suitable for estuarine areas. Background technique [0002] Sea bass, the scientific name Chinese sea bass, is also known as perch, seven star perch or Zhaihua, etc. It belongs to the genus Perciformes, Pteridae, Perch subfamily, and Perch. Because Chinese seabass breeds and grows along the coast, unlike California seabass that grows in freshwater, it is called seabass. Sea bass is mainly distributed along the coast of my country, Japan, and North Korea, and is one of the main high-quality marine fish in my country. At the same time, sea bass is the first of the four famous fish in the Pearl River Basin and is suitable for breeding in a variety of waters, such as freshwater ponds, seawater ponds, cages, and inland saline-alkali waters. [0003] However, the traditional seabass breeding area in China is the coastal area of ​​Fujian Pr...

AI Technical Summary

Problems solved by technology

Due to the great difference in water quality conditions, especially the salinity, between the coastal areas of Fujian and the estuary of the Pearl River Delta, the mortality rate of fry is high after being transferred from the coast of Fujian to the estuary of the Pearl River Delta every year, resulting in high fry costs.
