Artificial cultivation and domestication method for hucho taimen seedling

Abstract

An artificial culture and domestication method for a fingerling of Hucho taimen relates to the aquatic product culturing field which solves the problem that the current culturing technology is not suitable for the fingerling of Hucho taimen and can be finished by the following four phases: 1. cleaning a hatching slot 2 to 10 times a day and picking out dead eggs, dead fingerling and egg skin; 2. feeding zooplanktons for 4 to 7 days and 6 to 8 times one day; 3. feeding the zooplanktons and water earthworms for the first 3 to 5 days; then feeding the water earthworms for 4 to 5 times a day for the next one week; then feeding massive materials once every morning for three weeks and feeding the water earthworms in the daytime and at night for 4 to 5 times a day; 4. feeding artificial feedstock in the morning and massive materials in the daytime for 2 to 3 times a day and the water earthworms at night during the first 2 to 3 weeks; and feeding the artificial feedstock for 3 to 4 times a day by every 2.5 to 3 hours for one time and feeding the water earthworms at night after the next 2 to 4 weeks; feeding the artificial feedstock four times a day for the last 15 days and finishing the domestication work. The domestication method of the invention has the advantages of simple and convenient operation, low cost and good domestication fingerling quality.

Description

technical field [0001] The invention relates to the technical field of aquatic product cultivation, in particular to a method for artificially cultivating and domesticating jellyfish seedlings. Background technique [0002] Zheluo salmon, whose English name is Hucho taimen, belongs to the family Salmonidae and belongs to the genus Zheluo. It is the fastest growing and largest salmonid fish, weighing several hundred catties. Zheluo salmon is a famous and precious cold-water fish in my country. It has tender meat and delicious taste. It is very popular among the masses and has high economic value. Zheluo salmon has a distant relationship with the main cultured species of salmon and trout in my country. It has strong disease resistance to the current salmon and trout epidemic, so it has the advantages of easy to master the breeding technology. At present, there is no specific operation technology for the domestication of juvenile salmon juveniles in China. Although the salmon ...

Problems solved by technology

At present, there is no specific operation technology for the domestication of juvenile salmon juveniles in China. Although the salmon belongs to the family Salmonidae, its breeding time is different from that of most short-day salmonids that spawn in autumn and winter. The spawning time is between From May to June, the digestive system development of its larvae and juveniles has the duality of short-day salmonids and cyprinids that spawn in spring and summer, so the seedling cultivation techniques of other fish are not suitable for cultivating Zheluo salmon seed
