Abstract

Available information on the length-weight relationship, age and growth for some elasmobranch species was compiled and growth parameters discussed. Food and feeding habits studied for some species indicated preferences, except tiger shark, for certain food. In some cases there is shifting of food habits as the young shark grows to adulthood. Starvation of female sharks is a notable feature during advanced stage of pregnancy. The three types of development exhibited by different species are discussed. The size of litter, the relationship between the length of mother and litter size and fecundity are dealt with. Landings of elasmobranchs over the years were steadily increasing. There was spurt in landings during mid seventies. In recent years the elasmobranch production appeared to be stabilizing and a sign of stagnation in the landings is evident. Group wise, reqion wise and gear wise landings are discussed.
