Abstract

The invention discloses an artificial breeding method for Epinephelus tukula. The method comprises the following steps: (1) selecting parents; (2) culturing the parents in a pond; (3) culturing parent fishes in an anestrous season; (4) performing strengthening cultivation before reproduction; (5) performing artificial reproduction; (6) collecting and treating oosperm; (7) hatching the oosperm. Through parent culture of the Epinephelus tukula, parent fishes are made to lay eggs, and the oosperms are used to hatch fries, and the fries are cultured into fingerlings for breeding. The method provides a reasonable solution which is high in hatching rate for developing cultivation of Epinephelus tukula in a large-scale manner.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to an artificial propagation method of black-spotted grouper. Background technique [0002] Black-spotted grouper, (scientific name: Epinephelus tukula), commonly known as money spot, also known as blue-bodied large grouper, is a fish belonging to the genus grouper of the family Perciformes in the order Perciformes. Distributed in the Indo-West Pacific region, from the Red Sea, East Africa to Queensland, Australia, the habitat depth is 10-150 meters, the body length can reach 200 cm, and the weight is 110 kg. [0003] Black-spotted grouper is a rare warm-water fish in the world. It mainly lives in coral reef areas. It is a bottom-dwelling fish and is carnivorous. It feeds on fish and crustaceans and can be used as food fish and game fish. The body size is second only to the saddle grouper, and it grows faster. It is a grouper species with great breeding prospects. [0004] At ...
