- Abstract
Fishery and population characteristics of the Indian white shrimp, Penaeus indicus , were studied in Pulicat Lake, on the southeast coast of India, using the FiSAT software package. The asymptotic length ( L ∞ ), growth coefficient (K) and arbitrary origin of growth (t 0) were estimated by the ELEFAN method to be 16.18 cm, 0.60 year−1 and −0.18 year, respectively. The asymptotic length ( L ∞ ) was calculated as 16.09 cm using the Wetherall method. The growth performance index (Ø′) was found to be 2.19. The mortality parameters Z , F and M were computed to be 3.85, 2.30 and 1.55 year−1, respectively. The pattern of recruitment was observed to be year-round, with a peak from June to September. The total stock, annual catch and exploitation rate for P. indicus were estimated to be 1518.43 tonnes, 809.3 tonnes, and 0.59 year−1, respectively. The estimated Maximum Sustainable Yield (MSY) was found to be 131.95 tonnes less than the annual catch. The stock of P. indicus was found to be over-exploited, so it is suggested that the effort level be reduced by 16.3% in order to sustain this resource in Pulicat Lake.
