Abstract

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.
