Description With the establishment of the frozen shrimp industry in Cochin during
the past few years the demand for large-sized prawns is ever on the increase
both from the backwater as well as marine prawn fishery. Out of the three
or four species of prawns contributing to the commercial fishery of the backwater
area, Penaeus indicus is the most important species which is utilised
in the frozen shrimp industry because of the comparatively larger size it
attains in the backwater before migrating back to the sea. According to
Menon and Raman (1961) the biggest prawns of this species caught in the
stake nets of Cochin backwater measured between 130 and 140 mm. in total
length. As a result this particular species is in great demand, especially
the large-sized specimens. So with a view to determine the availability of
the larger sizes of this species in the commercial catches throughout the
year the catches were sampled and analysed regularly. The catches of the
important types of nets employed in the fishery were analysed separately
in order to find out the advantage, if any, in using a particular gear for
obtaining the larger size groups required for the industry. The results of
the study carried out during the four years 1955 to 1958 are presented here.
