Objective To study and master the techniques of long-distance transportation, translocation domestication and parent fish cultivation of Silurus glanis Linnaeus endemic to the Ili River, so as to lay a foundation for the protection, development and utilization of Silurus glanis Linnaeus resources.

Methods Special water tanks, plastic bags and foam boxes for live fish, conventional wet transportation with water were used for the long-dislance transportation to the domestication base by airplanes and, comparative studies on ex-situ domesticalion were carried out by using land-based canvas ponds and standard ponds.

Results 67 wild Silurus glanis Linnaeu were transported over long distances,with body lengths and weights ranging from 31.0 to 90.0 cm and 210.0 to 7000.0 g. The survival rate was 98.5%. 25 wild Silurus glanis Linnaeu were placed in a land-based canvas tank, resulting in an injury rate of 72.0% and a mortality rate of 4.0% within 3 days, respectively. When 65 wild Silurus glanis Linnaeu (including 24 transferred from a land-based canvas pond) were reared in a standard pond for 5 years, the survival rate was 61.5%, and 40 parents were bred with body lengths and weights ranging from 74.5~103.0 cm and 3219~9701 g, respectively.

Conclusion The long-distance transportation of Silurus glanis Linnaeus endemic to Ili River by road and air transport has a high survival rate. Road transportation is less costly and risky and is not limited by the size of the fish, resulting in better outcomes than air transportation. The domestication method of land-based canvas pond is easy to cause injury or even death of Silurus glanis Linnaeus, and the feasibility is poor. Standard pond domestication is more effective for Silurus glanis Linnaeus, and the survival rate of domestication is as high as 97.7% in 4~5 years, and 40 original parent fish of Silurus glanis Linnaeus can be bred to adapt to standard ponds, and have strong physique and can reproduce, and fully solve the transportation, domestication and parent fish breeding technology of Silurus glanis Linnaeus.
