Description An account of the region-wise shrimp landings by the trawlers operating from Bombay, Karwar,
Mangalore, Cannanore, Cochin, Mandapam, Tuticorin, Visakhapalnam and Calcutta bases is given. The
catch per hour of shrimp returns by the trawlers is taken as the basis for determining the area-wise and regional
abundance. Productive areas which have fairly constantly given high catch rates in different regions have
been charted. In the west coast the catch rates have been found to increase north to south, from Kutch to
Cochin. Productive areas occur on the continental shelf in the Gulf of Cambay, off Bombay, Ratnagiri,
Vengurla-Dabhol, Karwar, Mangalore, Cannanore, Cochin and Alleppey. On the east coast the shrimp
catches are comparatively less. However some productive prawn grounds have been located off Tuticorin,
Mandapam, Kakinada and Visakhapatnam. In West Bengal also fairly productive grounds have been
recorded from the Eastern Channel, off Debi-Prachi rivers and the Western Channel. The seasonal and
depth-wise abundance of shrimp species in different regions has been investigated.
