Method for transforming rainbow trout into trout

Abstract

The invention takes a method for developing and breeding rainbow trout and transforming the rainbow trout into trout as a task. Through screening a rainbow trout body with the weight of 200g-300g among the rainbow trout, the screened rainbow trout body is raised for 3-10 days in fresh water within the temperature range of the seawater temperature +/-3 DEG C and is stopped to be fed with fodders during the period, then the screened rainbow trout body is transferred to be raised in seawater, and thus the task provided by the invention can be solved.

Description

technical field [0001] The present invention relates to a method for breeding rainbow trout and converting it into salmon trout. Background technique [0002] Rainbow trout is a freshwater fish belonging to the family Salmonidae of the order Salmoniformes, characterized by distinct black spots all over the body, and a red to purple-red pattern on the side of the body from the gills to the caudal fin.

The total length is usually about 40cm, and it is basically a river residual fish that lives in fresh water all its life. In summer, it also lives in cold water with a water temperature below 12 degrees Celsius, especially in fast-flowing, oxygen-rich rivers. . It is carnivorous and feeds on aquatic insects, shellfish, crustaceans, eggs of other fish, small fish, etc. [0003] On the other hand, salmon trout and rainbow trout belong to the family Salmonidae of ...
