A kind of indoor artificial breeding method of tongue goby

Abstract

An indoor artificial breeding method of glossogobius giuris comprises the steps of indoor intensive breeding of parent glossogobius giuris, artificial ripening and hastening, artificial hatching and offspring seedling breeding. The indoor artificial breeding method is characterized in that after intensive overwintering breeding of the glossogobius giuris, the artificial hastening is performed, a lutropin releasing hormone A2 and a human chorionic gonadotropin are used as hastening hormones, after ripening and hastening of male and female parent glossogobius giuris, zygotes adhere to lining meshes of laying nests, the meshes to which the glossogobius giuris zygotes adhere are taken out, unfolded evenly and vertically hung in a hatching pond, after release, rich water seedling culture is adopted for primarily hatching yellow seedlings, after seawater rotifers are replaced by artemia nauplii, the seedlings are transferred to a water nursery pond of 10-15 m<2> for breeding, the seedlings are fed with artemia nauplii, blood worms, cyclops or opossum shrimps, and when juvenile glossogobius giuris grows to 15-25 mm in total length, the conventional fingerling breeding can be performed.

Description

technical field [0001] The invention relates to the breeding technology of gobies, in particular to the indoor artificial breeding technology of gobies. Background technique [0002] Tongue goby (Glossogobius giuris) Taxonomically belongs to Perciformes (Perciformes) Gobioides suborder (Gobioidei) Gobiidae (Gobiidae) Gobies genus ( Glossogobius ), is a kind of small and medium-sized fish at the bottom of the warm water, living in shallow beaches and brackish water areas of estuaries, and can also enter fresh water; tongue gobies are produced in the South China Sea and the East China Sea. The fish is round and long, with a cylindrical front , the tail peduncle is long and flat, the lip is thick, and the front of the tongue is forked; the tongue goby feeds on small fish, shrimps and organic debris; the tongue goby matures in about 2 years, with a body length of 15-20 cm; the breeding season is spring From April to August in summer, male fish build nests in sand and mud und...

Problems solved by technology

[0003] Tongue gobies are tender in meat, delicious in taste, good in nutritional value and high in economic value, and are deeply loved by fishermen along the coast. However, due to their small size and small number, they have not been paid attention to for a long time, and the research on them at home and abroad is also very limited. Only a brief description of its morphological characteristics and biological characteristics and an analysis of the nutritional components of the muscle of the tongue goby are found, but no artificial reproduction technology related to this fish has been seen; the tongue goby is also the food of young Chinese sturgeon Occupying a very important position in the composition, it can also be used as an ornamental fish in aquariums; in recent years, due to the impact of environmental pollution, the species of tongue gobies has been seriously attenuated; artificial breeding and breeding are required to provide for proliferation and release and restoration of natural resources. help
