| Kommentarer | Aquaculture developed slowly during 1959 to 1976. Since then, species became well-spread throughout the 16 provinces and autonomous regions. In recent years, more and more rainbow trouts have been infected by some diseases causing problems to fish farmers. The reason is probably related to the ability of diseases resistance decrease. So continuous introduction of new fish from place of origin is being practiced. Also Ref. 45864 and 55380. Ref: Tan, Y. and H.E. Tong, 1989 | ||||
