Description The penaeid prawns contributed to 16.70% of the total trawl landings at
Mandapam during 1986-'93. Out of the ten species represented in the catch,
four species namely Penaeus semisulcatus, Metapenaeopsis stridulans,
Trachypenaeus pescadoreensis and Metapenaeus burkenroadi supported the
fishery throughout the year. Contributing to over 50%, P. semisulcatus was
the dominant species, followed by M. stridulans. Over the years a gradual
decline of P.semisulcatus in the species percentage composition and a steady
increase of that of M. stridulans was observed. The change in the species
composition during 1986-'93 has been discussed. May to August was the peak
season for the fishery. Two peak seasons, one during May-August and the other
during November-December were observed for P. semisulcatus. The annual
fishing effort fluctuated between 3,54,055 and 6,48,513 hours with an average
of 4,90,361 hours. The annual prawn catch ranged from 561 to 1,065.8 t, the
average annual catch being 703.5 t. The annual catch per hour ranged from
0.8 to 2 kg. The MSY and corresponding optimum fishing effort was 726.2 t
and 5,61,415 hours respectively.
