Abstract

The invention provides an epinephelus fuscoguttatus and epinephelus tukula hybrid artificial breeding method. The method includes: carrying out staged feeding in an indoor pond with water depth of 1-2m; in a first stage, releasing newly hatched fry of epinephelus fuscoguttatus and epinephelus tukula hybrid into the pond, and feeding with 50-100micron powdery feed A from the first day to the ninthday, wherein the powdery feed A is prepared from soybean meal, squid paste, coconut oil, mannan oligosaccharide, antibacterial peptides, malic acid and astaxanthin, and the daily feeding amount is 10-15% of the fish weight; in a second stage, feeding with 80-200micron powdery feed B from the tenth day to the twenty-fourth day, wherein the powdery feed B is prepared from soybean meal, corn flour, ginger powder, coconut powder, brown sugar, herba paederiae leaf powder, ground pepper, taurine and lactic acid bacteria, and the daily feeding amount is 15-20% of the fish weight; in a third stage, feeding with granular feed C from the twenty-fifth day to the fortieth day, wherein the granular feed C is prepared from corn flour, peanut meal, artemia powder, compound algae powder, rhizoma calami grass meal, folium musae powder and herba paederiae leaf powder, and the daily feeding amount is 20-25% of the fish weight. By adoption of the method, high survival rate in breeding is realized, and obtained epinephelus fry are large in size.

Description

technical field [0001] The invention relates to the technical field of grouper seedling breeding, in particular to an artificial seedling raising 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. ...
