[0079] Step 1: Broodstock selection and domestication

[0080] (1) The choice of broodstock

[0081] In March of each year, 100 male and female broodstocks of seabass are collected and selected from the Yellow and Bohai Sea and Beibu Gulf regions. The selected broodstock are all healthy, weighing at least 3Kg, bright in color, no pests, no damage, and have a typical biological form. feature. The body weight of the sea bass broodstock selected in the present invention is about 3.5 Kg.

[0082] (2) Domestication of broodstock

[0083] a. Domestication of salinity

[0084] Due to the difference in water salinity between the origin and domestication of seabass broodstock, the difference is about 15‰. When the seabass broodstock arrives at the domestication place, the seabass broodstock is domesticated to reduce the salinity, so that the seabass broodstock can adapt to the domestication place. Water source conditions, the salinity of the aquaculture water body is reduced by 1‰ to 2‰ per d...

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...
