Title Stock assessment of Metapenaeus monoceros
(Fabricius) from Cochin waters, Kerala

Subject Prawn and Prawn fisheries
 
Description Based on the catch and effort, and length distribution data of Metapenaeus
monoceros landed by shrimp trawlers at Cochin Fisheries Harbour during
1991 - 93, an attempt has been made to assess the stock of this species in the
Cochin waters. The average annual instantaneous rate of total mortality was
estimated 7.06 and 7.75 for females and males respectively. The estimated value
of annual natural mortality (M) was 2.35 and it was assumed to be the same for
both sexes. The estimate of fishing mortality rate (F) was 4.71 for females and
5.40 for males of M. monoceros. The average rate of exploitation (E) was 0.70
and 0.67 respectively for males and females. The average standing stock size of
M. monoceros for the period under study was 10.55 t for males and 28.65 t for
females. The Thomson and Bell and the Beverton and Holt yield per recruit
routines in the LFSA are used to explain the present status of fishery which shows
that there is no adverse effect of fishing on the exploited stock of M. monoceros
from the southwest coast off Cochin.
