Embodiment 1

[0028] 1. Temporary raising of fry before opening the mouth to tame food:

[0029] Taming location: Yadong Salmon Breeding Base, Yadong County, Tibet (Shanghai Ocean University Industry-University-Research Base).

[0030] Temporary breeding method: Put the fish fry with yolk sacs after they have emerged from the film into a fiberglass tank for temporary breeding, and the stocking density is 10,000±100 fish / m 3 Water body; the water temperature of the glass fiber reinforced plastic tank is kept at about 13.0°C, the water depth is 20cm, and circulating water is used, and the dissolved oxygen in the water body is 6.5±0.5mg / L

[0031] 2. Selection of time point for mouth taming:

[0032] Before opening the mouth to tame food, observe the absorption of the yolk sac of the fry once a day; after 20 days, the accumulated temperature reaches about 200-300°C. Most of the fry can swim at the bottom, and when about 20% of the fry can swim to the water surface, it is determined as the be...

Abstract

The invention relates to the field of aquaculture, in particular to an opening taming method for Yadong salmon fry. The invention provides a mouth taming method for Yadong salmon fry, comprising: feeding egg yolk filtrate to fry; mixing egg yolk filtrate and microcapsule bait to feed fry; feeding microcapsule bait to fry. According to the biological characteristics of Yadong salmon, the inventors of the present invention provide a method of domesticating large-scale artificially bred Yadong salmon fry.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to an opening taming method for Yadong salmon fry. Background technique [0002] Yadong salmon (Salmo truttafario Linnaeus), also known as river salmon, grayling, catfish, Yadong fish, etc., is commonly known as flower fish, belonging to Salmoniformes, Salmonidae, Salmoninae, The genus Salmo was discovered in Yadong River, Yadong County, Tibet Autonomous Region, my country in 1960 by the staff of the Institute of Zoology, Chinese Academy of Sciences. This species is a new species recorded in my country, and has not been found in other ecological environments in China. It has the same body and synonym with brown trout (browntrout, Salmo trutta), which is an imported species and is an important cold-water economic fish in the Tibet Autonomous Region. Brown trout, originally distributed in Europe, North Africa and West Asia, is an important commercial fish with important economic and fishing...
