Abstract

Psenopsis cyanea usually occurs in deeper waters between 250 to 300 m depth in schools. They are irregularly and west distributed off the east coasts of India and off Sacotra and the mouth of the Gulf of Aden. The normal pattern of landings and species composition along the Kakinada coast changed complete by during the period due to the sizeable contribution of deep sea species in the catch. P.cyanea appeared in large shoals along the shallow coastal waters of 5-15 m depth along with the other deep water species such as Priacanthus sp. Decapterus tabl and Upeneus sp. and were caught in large quantities by trawls and gillnets. The landing of deepwater groups lasted for about 12 days. P. cyanea and other species which usually occur in the deep cold water areas might have moved towards the shallow coastal region due to upwelling of the cold deeper water towards the surface, where they were caught by trawls and glllnets.
