Description The paper deals with the hooks and line fishery along North Kerala during 1979-1985. Marine
cat-fishes were traditionally harvested from this area by non-mechanised gears, such as hooks and line,
drift net and boat-seines till early sixties. The operations by hooks and line yielded a steady catch.
The catfishes alone contributed about 90% in the hooks and line landings. The dominant species in
the landings were Tachysurus tenuispinis, T. dussumieri and T. thalassinus from the depth ranges of 40-70
m and T. serratus from 10-30 m. T. tenuispinis is vulnerable to the gear at the age of 3 years and above
and T. dussumieri, T. thalassinus and T. serratus at the ages 4, 2 and 6 years and above respectively.
Introduction of trawlers and purse seiners initially contributed to a sudden hike in its production.
But exploitation of juveniles and eggs/embryos carrying male brooders on large-scale, ultimately
resulted in low recruitment. As brooders are not susceptible to fishery by hooks and line, it is suggested
to intensify the catfish fishing by this gear.
