Problems solved by technology

Existing rainbow trout farming is mainly extensive pond culture. During the breeding process, it is vulnerable to parasite attack and easy to be infected by viruses and bacteria, resulting in low survival rate of rainbow trout. In order to improve the disease resistance of rainbow trout, most Farmers choose to add antibiotics to improve the disease resistance of rainbow trout, but long-term use of antibiotics will not only endanger human health, but also cause pollution to the environment

Abstract

The invention belongs to the field of aquaculture, and discloses a breeding method capable of improving disease resistance of oncorhynchus mykiss. The method comprises the following steps: washing a pond pasted with cement, and disinfecting the pond by using lime water; sprinkling a fertilizer on the water surface of the pond; selecting fry with equal sizes and a body length of 3-5 cm, and throwing the fry according to a fry throwing amount of 5000-10000 / mu; after the fry are thrown, performing feeding by using fry bait, wherein feeding is performed once separately in the morning and evening,and feeding is performed according to a feed amount of 5-10% of a body weight of the oncorhynchus mykiss every time; after the fry are mature, performing feeding by using mixed feed, wherein feeding is performed according to a feed amount of 10-15% of a body weight of the oncorhynchus mykiss every time; and performing comprehensive sterilization on the fish pond for one time every month, and regularly removing sediments at the bottom of the pond every month. The method provided by the invention has simple operation, and the oncorhynchus mykiss has high autoimmune function and disease resistance, a high survival rate, a high growth speed and high economic benefits.

Description

technical field [0001] The invention belongs to the field of aquaculture, in particular to a breeding method for improving the disease resistance of rainbow trout. Background technique [0002] Rainbow trout, a cold-water carnivorous fish belonging to the family Salmonidae, is native to the United States. Because of its individual body, there is a purple-red and pink, wide and bright red rainbow band along the side line, which goes straight to the base of the caudal fin. The period is particularly bright, like a rainbow, hence the name rainbow trout. There are no thorns in the rainbow trout meat, easy to digest, rich in vitamin D, iron, unsaturated fatty acids, and also contain essential amino acids, minerals, vitamin A and vitamin D and other elements needed by the human body, which can activate brain cells and delay brain damage. Aging, reducing blood lipids, preventing arteriosclerosis, myocardial infarction, and strengthening muscles and bones. In addition, rainbow trou...
