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...

Various morphometrical relationships were demonstrated that the males of M. planipes and A. lunaris were larger in size and heavier than females (4.34g ± 0.9g; 14.86 ± 6.8g and 3.87g ± 0.6g; 11.66 g ± 5.4 g) respectively. There was a negative allometry for both male and females of M. planipes and A. lunaris fo...

...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...

Total carapace length (CL) and weight (W) of each individual were recorded with an accuracy of 0.01 cm and 0.01 g, respectively. During the sampling period, a total of 5932 crab individuals belonging to five species were collected and...

Amino acid score (AAS), chemical score (CS), and meal size amino acid score (MSAAS) were calculated. In August, when E. verrucosa breeds densely, the crude protein (%13.52) rate was found to be the lowest compared to other months. In Sep...

As this waste contains protein that could enhance growth rate, it could be a good choice to be used as alternate source of feed for fighting fish. The objectives of this study are to determine proximate composition in formulated fish feed using crustacean waste and to examine effect of crab waste i...
