Outboard ring seine is one of the major gears operated in Kerala which
contributes about 37% of the total landings in the State. Oil sardine (Sardinella
longiceps) and Indian mackerel (Rastrelliger kanagurta) are the two species that
account for about 84% of the ring seine catch. The ring seine fishery began in
the State by mid eighties and grown into a major fishery over the years. An
assessment of the ring seine fishery in the state through nonequilibrium surplus
production model was made in this study by using time series data on catch and
effort of ring seine in Kerala during 1986-2004. An index of relative biomass at
and an index of net production rate mt were computed, apart from fishing
mortality rates Ft, maximum sustainable yield (MSY), effort corresponding to
MSY and biomass corresponding to MSY. Results revealed that the ring seine
fishery in Kerala is close to the state of equilibrium. Behaviour of mt and Ft were
almost similar showing characteristics of fully developed fishery and the pattern
of their difference mt-Ft indicated that the status of ring seine fishery in Kerala
is close to the optimal level at present.
