The results showed that the interpretation ratio (IR) of the 6 factors reached 83.76%, within which the IR of the RELE is the largest (26.02%). The IRs of NMV and PTV also exceed 20% (20.21% and 20.10%, respectively). The IRs of SST, PMV and NTV are similar, and all are between 5.6% and 6%. The catch of P. trituberculatus positively correlated with the fishing efforts of main catch vessel...

...ify;">The Chinese mitten crab (Eriocheir sinensis) is one of the most studied and deconomically important crustaceans in China. However, the production scale does not meet the market demand. This resulted in excessive fishing, which almost caused extinction of the species in the the Yangtze River. Therefore, it is very urgent to carry out genetic breeding to improve yield. In this study, we developed SSR markers by transcriptome, which could be used to geneti...
