Abstract

The invention provides an epinephelus fuscoguttatus and epinephelus tukula hybrid artificial reproduction method. The method includes: selecting healthy epinephelus fuscoguttatus at the age of 5 or older as a female parent; selecting healthy epinephelus tukula at the age of 7 or older as a male parent; subjecting to breeding strengthening respectively, and carrying out artificial fertilization andhatching to obtain fry. By adoption of the artificial reproduction method, egg quality of epinephelus fuscoguttatus and semen quality of epinephelus tukula are optimized, the fertilization rate and the hatching rate are increased remarkably, and a great foundation is laid for acquisition of high-quality hybrid epinephelus.

Description

technical field [0001] The invention relates to the technical field of grouper reproduction, in particular to an artificial propagation method for hybrids of brown-spotted grouper and blue-bodied grouper. Background technique [0002] Brown-spotted grouper (scientific name: Epinephelus fuscoguttatus), belonging to the order Perciformes, Scorpidae, and the genus Grouper, also known as tiger spot and brown-spotted grouper, is distributed in the Red Sea, the Indian Ocean, the east coast of Africa to the Pacific Ocean, Polynesia, and North Dakota. Ryukyu Islands, south to Australia, Taiwan Island, South China Sea Islands, Penghu Islands and other sea areas, etc., the habitat depth is 1-60 meters, and the body length can reach 120 cm. It belongs to warm water nearshore and coral reef fish, and lives in coral reefs with clear water quality. ,lagoon. Carnivorous, feeds on fish, cephalopods, and crustaceans, and can be used as food fish, farmed fish, and ornamental fish. Brown-spo...
