Description The Marine catfishes are one of the most vulnerable resources for irrational harvest during their migratory and breeding phase. With the advent
of mass harvesting gear like purse seine and trawlers, there has been a continuous onslaught on this resource during the periods of South bound
or North bound migrations parallel to the coast. The damage is further aggravated when their spawning shoals are exploited from the surface
often causing large scale destruction of parents and egg / embryos, leading to recruitment overtishing. Their production showed a continuously
declining trend all along Indian coast, preferably along the SW and SE, since 1980's from 67,666 t (1982) to 37,518 t ( 1995). The paper gives
the possible migratory direction and seawns of the resource. It is attempted to correlate the surface drift with the seasonal migntions. Various
management practices are proposed to conserve the threatened group and suggested possible lines of exploitation of the non migntory species
from distant waters, in the middle shelf and estimated their potential.
