Abstract
The annual yield of prawns in the Mangalore coast showed considerablefluctuations. The MSY is estimated to be around 1800-1900 t, at an effort level of
28,000 boat-days. The best catch of 3644.6 t and CPUE of 120 kg were obtained
during 1973-74. Thereafter, the catch and CPUE declined almost continuously
coupled with a reduction in the average size of prawns, even though there was a substantial
increase in effort, indicating depletion of the stock. Metapenaeus dobsoni
and Parapenaeopsis stylifera contributed to around 85% of the annual avearge
catch of prawns. The annual mean length of males and females of M. dobsoni
and M. affinis and males of P. stylifera decreased considerably during the present
period of observation compared to earlier years. In the case of females P. stylifera,
however, the decrease was only marginal
