Study on the poputalion dynamics of siboga squid Doryteuthis sibogae in Thoothukkudi coast revealed that the seasonal
change has define impact on the growth of this species.The. study infers that the cod end mesh size of the trawls of Thoothukkudi has to be increased from 10 to 25 mm to increase the yield per recruit. Further the effort should be reduced and maintained at the exploitation ratio of 0.45 to get maximum yield per recruit.
