Canonical Correlation Analysis for Determination of Relationships Between Different Length Measurements and Body Weights of Common Cuttlefish (Sepia officinalis)

Levent Sangun, Soner Cankaya and Onder Duysak    

Abstract: In this study, canonical correlation analysis was applied to estimate relationships between length characters mantle length (cm), upper hood length (cm), lower hood length (cm), cuttle bone line zone length (cm), cuttle bone free zone length (cm) and weights characters body weight (g), stomach weight (g), stomach wall weight (g), digestive gland weight (g) of 697 cuttlefish (Sepia officinalis) populations caught from Iskenderun bay from 2006-2007, Eastern Mediterranean region, Turkey. The first 3 of the estimated canonical correlation coefficients between the pairs of canonical variables were found significant (0.949, 0.358, 0.294 and p<0.01). The results obtained from canonical correlation analysis indicated that mantle length had largest contribution for the explanatory capacity of canonical variables estimated from length characters of 697 cuttlefish (Sepia officinalis) when compared with other length characters while body weight had largest contribution for the explanatory capacity of canonical variables estimated from weight characters when compared with other weight characters. The results of this study showed that mantle lenght should be used with the aim of estimating weight per Sepia officinalis individuals in common cuttlefish genotypes.
