This study mainly through the different color of wild and farmed shrimp patterns of Japan biogas parameters of analysis, germplasm resources protection offer some suggestions. 20 randomly selected each shrimp with vernier caliper for measuring parameters, were measured in long, long, long head Xiongjia, the first Xiongjia wide, long and abdominal abdominal wide. Recommends the adoption of cluster analysis, principal component analysis and discriminant analysis of these patterns of parameters for analysis. Cluster analysis shows that wild black and green groups in the wild blue on the very close relationship with the farming group in the more distant relationship; principal component analysis showed that the three principal components of the different color of wild and farmed shrimp Japan's contribution rate of biogas Namely, composition 1:40.037 percent, the principal component 2:27.01 percent, the principal component 3:17.901 percent, the rate of contribution: 85.617% (Table 2)
