The extrusion tectonic model has been widely accepted to explain the strike-slip faults around the Tibetan Plateau. Previous studies indicate that the lower crust flow is the main drive force of the extrusion tectonics. Whether mantle extrusion process occurred during the Cenozoic uplift is a major problem to be addressed, which is significant for understanding the uplift mechanism and tectonic evolution of the Tibetan Plateau.展开更多

[Method]A total of 171 specimens of sinipercine were collected from Jinjiang River and its branches,identified and statistically counted.[Result]There were three species of wild sinipercine,including Siniperca scherzeri,Coreoperca whiteheadi and Siniperca kneri,with occurrence frequencies of100%,66. 7% and 50%,respectively. They were common species in the river,and S. scherzeri was dominant. The total allowable catch(TAC) of the three species was not big,and the individuals captured were generally small,and with rare mature individuals. [Conclusion]The resources of sinipercine had a preliminary recovery in the region after the foundation of the national resources protection area for aquatic resources in Jinjiang River in 2009.展开更多
