Trawl fisheries sector account more than 50% of the marine
fisheries production of India. Annual average fish landing from
trawlers was 17, 21, 000 t (2008-2011), which formed around
51 % of the marine fish landing of the coast. In this about 51%
of the catch was contributed by the west coast and remaining
by the east coast of India. Recent studies of the trawl fishery in
India have shown that incidental catches/low value bycatch
(LVB) landing and utilization has increased over the period of
time. The present study is based on the data collected from
major trawl landing centres along the coast of India during the
period 2008-2011.The estimated landing of low value bycatch
(LVB) in trawl fisheries, increased from 14 % in 2008 to 25 % in
2011, which is reflected as reduction in discard volume by
trawlers. On an average the highest quantity of LVB landed was
in Veraval (50,000 t) and in Mangalore, LVB landing increased
from 3% in (3000 t) in 2008 to 26 % (12,000 t) in 2011.In
Mumbai, the percentage of trash fish landed remained around
5% during the study period. In Calicut, the LVB landed in 2011
contributed 26% to the total landings by the trawl. In Kochi,
Kerala the total LVB landed in 2011 was 1,992 t forming 7.2 %
of the total landing. In Chennai, Tamilnadu, the LVB landing
which was 13 % in 2008 increased to 17% in 2011, while in
Visakhapatanam, Andhra Pradesh, LVB landing showed a steady
increase from 2% in 2008 to 21% in 2011. The landing centre
price for LVB showed an increasing trend due to increased
demand for trash fish for the production of fish meal and
fertilizer. The dominance of finfishes in LVB found to increase
the value of LVB and the value realized for 30,000 t of LVB in

Mangalore in 2011 ( Rs.280 million) was more than that
realized for 50,000 t of LVB in Veraval (Rs.200 million). A
disturbing trend observed from the studies in Mangalore was
that, the sardines in trash fetches higher price in some seasons
(upto Rs.16/kg) compared to a lower price when landed in fresh
form, and the percentage of sardines in LVB is found to be very
high (24% in 2010). This trend may cause a severe threat to the
protein availability to the rural poor. Looking at the trend of
trawl landing during 2008-2012, it is seen that even though the
trawl landing showed an increase over the period of time, the
edible portion of the trawl landing did not show any significant
increase rather showing general declining trend. Study on the
bycatch from different centres along the coast of India showed
that as many as 237 species / groups of marine fauna with
juveniles of commercially important fishes were landed as LVB.
Increase in utilization of LVB (which was discarded earlier) from
trawl fishery, a trend which is market driven and its implication
on the ecosystem and marine fisheries production of the country
is discussed in this paper.
