摘要:The length-weight and other allometric relationship of Turbo brunneus from Tuticorin (Southeast coast of India) coastal waters have not been subjected to through analysis earlier. Totally 778 males and 749 females were collected for the present study. For Length-weight analysis, the males and females of Turbo brunneus were fit with linear equation individually. The present study shows that the differences in the growth rate between male and female snails may also leads to the variation. Analysis of covariance revealed significant difference between males and females. The correlation co-efficient values between length and weight in male and female were significant. Changes in the constant allometry of length-weight relationship are associated with an increase in size and sexual maturity. The correlation co-efficient values between length and weight in male and female were significant. From the results obtained through the statistical analysis on various shell characters it is found that the shell of T. brunneus also conforms to the equiangular spire model as reported in other snails having turbinate shells.
