Shore seine at Kakinada

Subject Prawn and Prawn fisheries
 
Description The estimated annual prawn landings by shore-seines at Kakinada varied
from 13.9 to 57.3 tonnes during 1967-1971. July-Septembar was found to be the
peak season of the fishery. The catch was composed of Metapenaeus brevicornis
which formed about 60% of the landings. Other penaeid prawns occasionally
landed in commercial quantities were M. inonoceros, M. affinis, M. dobsoni,
Penaeus monodon and P. indicus. The landings of many of these species dropped
gradually from 1967 to 1971 indicating a decline in the fishery. The sizj-frequency
distribution for M. brevicornis indicated that females of 60-130 mm and males of
60-80 mm in total length dominated the fishery in most of the years. It was inferred
that females grow at a rate varying from 8.7 mm to 11.2 mm per month.
Males showed unimodal size distribution. The distribution of sexes in different
size groups indcated a preponderance of males up to 80 mm and females thereafter.
Length at first maturity for females of M. brevicornis was at 86 mm. Rips
prawns were found to be rare in the inshore waters indicating spawning migration
to offshore waters. Spent females were observed aUthrough the season with a peak
during Tuly-October.
