The results showed that as 30 000 fries were released, 19 830 fingerlings of 1. punctatus were obtained after 270 d rearing, with the average body length of 21.2 cm, the average body weight of 216.5 g, the survival rate of 66.1%, and the fingerling harvest of 4 293.2 kg. Thus, it is effective and feasible to rear I. punctatus with residual heat resources of power plants in cold plateau zone.展开更多

The correspending conservation countermeasures aiming at various ecologi- cal and social problems of fishery resources in Tibet were put forward, including ex-situ conservation of some rare and endangered fishes, strengthening protection of gennplasm resources, establishing special and integrated nature reserves, and constituting environmental monitoring system for rare and special fish resources. Moreover, we should pay equal attention to economic development and environmental protection, strengthen propaganda and research, protect the existing habitat of rare and endangered species, and prevent invasion of Mien species, thereby ensuring sustainable development of fishery production.展开更多

This study made a systematic analysis of research progress of fishery resources in Tibet and pointed out that Tibet had abundant water resources, but the aquatic industry lagged behind; resource utilization was extremely limit- ed; and endangered species had not been timely protected. It was very difficult to promote popularity of aquatic industry in Tibet because of weak infrastructure con- struetion and a serious lack of relevant technicians. Actually, the aquatic industry in Tibet remained basically a blank. Therefore, it was both important and neces- sary to establish fishery resources monitoring network based on platean water resource system. Furthermore, initial ideas for further investigation of water resources were put forward.展开更多
