Description Globally, trawl is the major fishing gear used in marine
fisheries and in India, it contributes to more than onethird of the marine fish production. Trawl fishing has
been critically evaluated from a sustainability perspective, especially analysing its bycatch composition. Most
of the bycatch from trawlers contains valuable edible
species with high market demand. However, a portion
of the bycatch which does not have such demand in the
edible fish market, known as low-value bycatch (LVB),
continues to be a matter of concern from an ecological and
economic perspective. During 2017–19, 30–60% of trawl
landing in India was constituted by LVB, which was
mainly used for fishmeal preparation. To enhance the
value and utility of LVB, this study explores the possibility
of converting waste from LVB into edible resources using
pufferfish and triggerfish. It also highlights the positive
impact of efforts by different Government agencies for
bycatch mitigation like the implementation of minimum
legal size in reducing the juvenile component in bycatch,
with a social survey-based account of fisher’s perceptions
and suggestions on successful bycatch mitigation.
