A method for promoting production of rock seabream in flowing water and a method for cultivating larvae and juveniles

Abstract

The invention relates to a flowing-water type production-promoting method for barnacles and a method for cultivating larvae and juveniles, and belongs to the technical field of fish aquatic organism cultivation in aquaculture. The method for promoting production of the stone seabream flowing water according to the present invention comprises: 1) putting the sterilized broodstock into the broodstock pool to obtain domesticated broodstock; Jet flow for 15-20 days to complete broodstock mating and broodstock ovulation; 3) to raise the water level in the broodstock pond, and the floating eggs flow out from the overflow hole of the broodstock pond, and a baffle is set at the overflow port to drain the floating eggs to the overflow pipe for collection to obtain strips Stonefish eggs. The method of the invention can greatly increase the rate of obtaining fertilized eggs of the stone seabream, improve the survival rate of larvae and juveniles, and achieve the purpose of mass production.

Description

technical field

[0001] The invention relates to the technical field of fish aquaculture in aquaculture, and in particular to a method for promoting the production of barnacles in flowing water and a method for cultivating larvae. Background technique

[0002] Oplegnathus fasciatus, belonging to the order Perciformes, Oplegnathidae, Oplegnathus, is a temperate tropical offshore fish. Porcupine bream has beautiful body, bright color, tender meat and high nutritional value. It is a seawater fish with high economic value and ornamental value. The market price can reach as high as 300 yuan / kg. Through artificial breeding technology research, it is very hopeful that it will be developed into an emerging excellent variety for industrial farming, seawater cage culture, recreational fishery, and multiplication and release in my country. At present, research on the cultivation and reproduction technology of the broodstock of the stone seabream has been carried out in China, and a sma...
