Length- weight relationship and morphometric study on the squid <i style="">Loligo duvauceli </i>(d’Orbigny)(Mollusca / Cephalopoda) off Mumbai (Bombay) waters,west coast of India

Abstract

The length- weight relationship and morphometric study on the squid, <i style="">Loligo duvauceli </i>(d’Orbigny) is reported from Mumbai waters. The regression coefficient between the sexes was found to be not significant at 1% level. The ‘b’ value differed from the ideal cube law of ‘3’as is with the case of length- weight relationship studied on this species elsewhere. The morphometric characters indicated high degree of correlation among the compared characters. The study substantiated further that the length-weight relationship of squids do not follow ideal cube law. The morphometric characters compared here would be very useful for comparison with the same species in other geographical locations.
