Population dynamics of Malabar sole Cynoglossus macrostomus Norman \ud along Calicut coast

By M Feroz Khan and K Nandakumaran

Abstract

The size at fh maturity of ~oglossw macrostomus in sstimated aa 120 mm;the rpawn- \ud ing seaon is from October to May. The von Bertalanftj parameters of growth are estimated M \ud L = 139.9 mm, K 1.6117 and t 0 = 0.01 year. Tho length-weight relationship can be de- \ud scribed by the equation : W (g) = 0.00003759 L2"1zs (-). The inrtantaneour rate of total mor- \ud tality during the period is mtimatrd an 2.5. Length and ago at fh capture are 85 mm and 0.6 \ud year respectively. The maximum sustainable yield ir obtained at an E value of 0.96 when the \ud preeent E is only 0.4. Along the Calicut comt of North Kerala present average catch ir 959.08 \ud tonnes. Estimated MSY in 1694 tonma. The preaont effort can be doubled to hvvcrlt 1 646 tonnos
