1, the parent fish cultivation of environmental conditions: the parent fish cultivation of the fish pool requires a wide, smooth flow of water, the pool water is rich in dissolved oxygen. The usual area of 100-300 square meters.

2. Triploid red trout is an all-female red trout produced by hybridization between tetraploid red trout and common diploid red trout. It has a short growth cycle, low cost and good meat quality.　

3, red trout aquaculture is a high-density aquaculture, high technology, from the current level of red trout aquaculture technology, it takes more than three years to complete the production cycle of a commercial fish, a longer production cycle, higher inputs, in order to achieve better economic benefits, it is necessary to improve varieties, increase the growth rate of red trout, shorten the production cycle, and reduce costs.　

4. According to the latest developments in domestic and international trout farming, the problem can be effectively solved by adopting all-female triploid technology. Using this technology has the following outstanding advantages: First, the use of all-female triploid trout farming can improve the survival rate of trout by 10%, and can improve the growth rate of 10-20%. Secondly, the adoption of this technology can avoid the excessive consumption of feed due to gonadal development, reduce the aquaculture cost by more than 5%, and improve the economic benefits by 15% to 20%.
