    • Abstract

       

      The von Bertalanffy parameters of growth inPenaeus indicus are estimated as L=218·9 mm,K=2·0 per year, andt0=0·01 year in females and 227·2 mm, 1·8 per year and −0·0729 year, respectively in males. The instantaneous rates of mortality are estimated asZ=9·42,M=3·30 andF=6·12 in females and 12·73, 2·90 and 9·83, respectively in males. Various morphometric and length-weight relationships are worked out. At the current rate of fishing, the yield in weight per recruit is 23·05 g in females and 31·74 g in males. There is scope to increase the yield of this species by increasingF (i.e. effort).
