Abstract

The study presents a comprehensive account on the fishery, biology and population dynamics of Solenocera choprai along South Karnataka coast during 2003-2004. - ~ Trawling for the species was invariably carried out during the night time from a depth of 60 to 100 m . . .,..... Along Kamataka coast, S. choprai was landed only in two fisheries harbours, Mangalore and Malpe and 86% of' the catch was landed at Mangalore . . ".,.., Unique sandy belt occurring from 50 m depth off Karnataka coast was found to harbour the species, which have a habit of burrowing in the soft sandy substratum, with the anterUlules of the species forming respiratory tube enabling them to respire while burrowing in the sand. ~ The landing of S. choprai along the coast during the period of study showed a declining trend from the previous years, the landings in 2003 and 2004 were 1,445 t and 752 t respectively . . _~ Peak landing of the species was observed during September-October, immediately after the commencement of fishing after the cessation of southwest monsoon . . ~ The regression equations of length-weight relations between male and female were tested for equality showed that the values of slope and elevation differed significantly at I % level.
