Chakrabarti, K.
A growth study of the Crab Scylla serrata Forsk. In the Sundarbans
1981  Indian Journal of Forestry (4): 102-106

In this paper a statistico-bio-ecological study was made to probe into the length-weight relationship of the crab - _Scylla serrata_ and the co-efficient of condition for the said species was computed to determine a suitable criterion for maturity and hence to find out an index of potential extinction of this crab species in the estuarine environment of the Sundarbans. Different regression equations have been calculated so that statistical forecast has been possible for either of the two variates length and weight of the crab species. If one of the variates is known, other could be derived easily from the prediction formula. Statistical tests of significance have indicated that a logarithmic regression exists between length and weight in both male and female crabs and that the female crab attains maturity much earlier than that of her male counterpart.
