Abstract Responsible fishing regime requires that fishing gear should preferentially catch the adult
fish at a particular age, which would maximize yield while permitting the juveniles and sub-adults
to escape and also minimize the catch of non-targeted and protected organisms. In
this review, selectivity characteristics of trawls are discussed in the context of their relevance
in conservation of fishery resources, development of selective fishing gears and fisheries
management. Different methods used for determining trawl selectivity are discussed along
with recent developments related to trawl selectivity such as evolution of selective trawls,
use of square mesh in trawl construction, and optimum mesh size determination for multispecies
trawl fisheries.
