虹鳟隶属鲑形目、鲑科、鲑属,系冷水性鱼类,原产于美国。生活的水温范围为0℃~30℃,最适生长水温为16℃~18℃。低于7℃或高于20℃,食欲减退,生长缓慢,超过24℃,摄食停止,机体衰竭以至死亡。河南故县水利枢纽管理局于2000年引进该品种,利用水库底层水饲养虹鳟取得了较好的效果。但在养殖过程中,由于密度较高、流水池水质调节不善,鱼病问题日趋突出。笔者根据养殖实践经验,总结了对虹鳟
Rainbow trout attached to the salmon-shaped head, salmonidae, salmon genus, Department of cold water fish, native to the United States. Water temperature range of 0 ℃ ~ 30 ℃, the optimum temperature of 16 ℃ ~ 18 ℃. Below 7 ℃ or above 20 ℃, loss of appetite, slow growth, more than 24 ℃, feeding stops, body failure and even death. Henan Guxian Water Control Project introduced the variety in 2000, and achieved good results by using the bottom water of the reservoir to raise rainbow trout. However, in the breeding process, the problem of fish diseases has become increasingly prominent due to the high density and poor regulation of the water quality in the flow pools. The author based on farming experience, summed up the rainbow trout
