Description Fish landings in India are of multispecies, exploited by
multigears. Species-wise stock abundance studies, in this
context, pose problems not normally encountered in the
case of single-species fishery for which evaluation of standard
effort is not difficult and models are available to study
such fishery in detail, Hence a new approach, considering
multispecies fishery as a whole, is taken up for study in this
paper where the relative contributions of mechanised crafts,
prawn fisheries and pelagic fisheries are considered for
detailed statistical analysis. This approach is found to be
useful when there are considerable fluctuations in the
landings which is the characteristic feature of marine fish
landings in India, In this analysis three assumptions are
made on the status of stock abundance and fishery independent
and dependent factors. These assumptions are not
contradicted by the analysis of variance. Three important
points emerge out of this study. In majority of the States as
well as on all India level, the trend of total landings was
similar to that of pelagic fish landings. Increase in the
intensity of mechanised effort has not relatively increased
prawn landings. Landings from mechanised units showed
an increase even when there was no increase in the
total landings thus indicating the impact of mechanised
crafts on the traditional fishing. In addition, this analysis
gives a broad indication on the limitations of the present
exploited fishing grounds in each of the maritime states
along the coast of the main land.
