Abstract

The invention belongs to the technical field of fish culture, and particularly discloses a breeding method for prolonging the service life of rainbow trout. The method comprises the following steps that 1, an aquaculture pond is selected; 2, rainbow trout fry are put; 3, culture management is carried out; 4, feed is put at the advanced fry stage; 5, water management is carried out. The rainbow trout is cultured through the culture method, the disease resistance of the rainbow trout can be enhanced, the survival rate is greatly increased, the obtained rainbow trout is fat, delicious and tender in meat, and the economic value is extremely high.

Description

technical field [0001] The invention belongs to the technical field of fish culture, in particular to a culture method for improving the lifespan of rainbow trout. Background technique [0002] Rainbow trout belong to the salmon family and are fish raised in cold water ponds. Rainbow trout is one of the four major freshwater aquaculture species with high yield and good quality promoted by the United Nations Food and Agriculture Organization to the world. It has been listed as a precious fish in the world. It has the advantages of high feed rate, rapid growth, easy fishing, high feed utilization, and artificial reproduction. Rainbow trout likes to live in waters with clear water, low water temperature, more dissolved oxygen and abundant flow. During the process of growth and reproduction, they have higher requirements on water temperature, dissolved oxygen, water quality, light and other conditions. When the temperature is lower than 7℃ or higher than 20℃, rainbow trout los...
