Abstract:

To understand the correlativity between Octopus variabilis’ body measurement and weight traits. Selecting Octopus variabilis 95 weighing about 200 g, which were captured in same batch, 12 body measurement including the length and wide of carcass, head and hopper, the length of the first, second, third and fourth tentacles, interbrachial membrane, volume and 2 weight traits comprise the weight of body and meat were measured. Analysis correlativity between each character adopted the correlation analysis. The results indicated that there was a extreme significant among the traits of carcass, head and hopper, and there a extreme significant in the 4 tentacles (P<0.01). Maximum Correlation coefficient present between body weight and meatweight (0.983), the next between volume and body weight (0.979). Established the optimization model of the body weight forecast the meatweight using the curvilinear regression: Wr=0.981Wt0.9843 (R2=0.9706).
