Title The status of fisheries for small tunas in India

Subject Tunas
 
Description The tuna resources presently exploited in India essentially comprise the small tunas such as
Euthynnus affinis. Auxis thazard, A. rochei, Thumus tonggol and Katsuwonus pelamis. The non-mechanised
and mechanised crafts engaged in the iishery have their operational range upto 50 m depth zone.
The drift/gillnets, hooks and lines and purse seines presently employed by these imits are multispecies
gear and tunas form part of the catch. The pole and line units in Lakshadweep exploit mainly skipjack
and young yellowfin tunas. Over the years the catch has increased considerably. The average
catch (1984-86) was 28,093 tonnes. E. affinis, Auxis spp. and K. pelamis constituted 55%, 16% and
13% respectively of the total tuna catch. The statewise, seasonwise distribution and abundance of
small tunas are briefly mentioned. The results of the studies on stock assessment indicated that higher
yield could be expected from the present fishing zone especially with respect to E. affinis and Auxis
spp. Augmenting production should be through diversification of the effort as well as expansion
of the fishing to the shelf edge. The pole and line fishing in Lakshadweep also offers scope for future
expansion. The need for correlating the environment with the fishery at the microlevel has been
stressed.
