Method to decrease mortality rate of trout fish on acclimation to seawater

摘要

The present invention relates to a method for reducing the mortality rate of a trout and a fish in a seawater flow process, and more particularly, to a method for manufacturing and selecting a male fish and a fish for breeding freshwater fish. And permitting the fry to be seawater. The present invention relates to a method for reducing mortality in the process of trout fishing. According to the present invention, it is possible to provide a low-mortality culture method in the stepwise seawater settlement of trout and fish such as rainbow trout, thereby improving the efficiency of the culture and contributing to the reduction of the operation cost of the aquaculture .;
