Abstract Gear selectivity plays a very important role in the management of
a viable commercial fishery. The enforcement of gears of high selectivity
is important for the protection of juvenile fishes by regulating the size at
first capture, the maximisation of yield per recruit and the reduction of
discarded quantities (Pope et at., 1975; Reeves et al., 1992., Cadigan and
Millar, 1992). The size selectivity of the trawl codend is primarily affected
by mesh size and secondarily by other factors such as mesh shape, twine
characteristics and net construction (Robertson and Ferro, 1988; Reeves
et al., 1992; Galbraith et al., 1994). The results of selectivity experiments
allow gear technologists to isolate the elements of gear or the harvesting
procedures that permit the escapement of unwanted bycatch. Selectivity
experiments also indicate the size and the species that are removed from
the marine environment with the use of a particular configuration or a
harvest method as well as those species that escape.
