Abstract

Tuna and billfish production from the Indian coastal waters, Lakshadweep and Andaman and Nicobar islands during the period 1985-'99 averaged 40,204 t. The contribution by E.affinis, Athazard, T.tonggol, K.pelamis and T.albacares (young ones) were 18,5041,6,8521,3,093 t, 3,3921 and 2,2111 respectively. Drift gill net was the major gear employed in the coastal tuna fishery. The length frequency data collected on the above species during 1990-'98 at seven centres along the Indian coast were analysed employing FiSAT programme to estimate their growth and mortality parameters, exploitation rates and relative yield per recmit.
