Description Analysis of length hquency dntnon Scomberomorus commemon gave the growth parametusIISL-, 146
cm and K, 0.78. TaLing M/K as I and 1.5, the MSY vdws for Kerala were estimated IIS 5 823 tonnes and
5030 tomes respectively. The nnnunlaverage cntch here stood at4 909tonnes. Yield per recruitstudiesrev-
the exploitntion as beyond the MSY level. A reduction in exploitation mte is necessary to bring the yield badc
to MSY level.
The estimated total mortality (Z) for Tamil Nadu was 3.09. MSY stood at 4 417 tonnes and 3 624 tonnes
for M/Kvalues of 1 and 1.5 respectively. With the avenge annual yield of 3 488 tonnes during 1984-88. a
duction in the explo~tation rate 1s required here also.
The estimates rnised to dl-India catch gave an MSY value of 23 284 tonnes and 19 733 tonnes for M/K
values of L and 1.5 respectively. Theavemgeannual all-lndiacatch at 19 171 tonnes showedtheScnmberornor~.r

whereas a decrew wll give an increased yield and CPm.
