Description The Godavari estuarine system of Andhra Pradesh supports a round the year penaeid prawn fishery.
The annual average penaeid prawn landings at Matlapalem, B. V. Palem and P.O. Moga landing centres
was 806.3 t, during 1979-'83 with peak catches during (Dctober-December. Twenty three species of
penaeid prawns contribute to the fishery of which M. monoceros, P. indicus, M. dobsoni, P. monodon,
M. brevicorins, P. semisukatus, P. merguiensis and P. japonicus are important in the order of
abundance. Variations in the seasonal abundance of the constituent species between years and between
the landing centres were noticed. Prawns in the length range of 40-100 mm (2-4 months old) formed
bulk of the catch. A growth rate of 16-18 mm/month in M. monoceros 27.5-32.5 mm/month in P.
indicus and 32.5-37.5 mm/month in P. monodon was discerible. In most of the species female
dominated in almost all the months and also in the larger length groups. The species composition
in the Godavari estuary during December and February-May was similar to that obtained in the
marine catches landed at Kakinada Fisheries Harbour. This may be due to the existence of somewhat
marine conditions (physico-chemical) in the estuary in those months.
