Abstract
The term bycatch refers to non-targeted species retained, sold or
discarded for any reason (Alverson et al., 1994). Catch process and
production of bycatch during fishing operations are represented in Fig. 1.
'Target catch' is the species or species assemblage primarily sought in
a fishery, incidental catch' is the retained catch of non-targeted species
and 'discarded catch' is that portion of catch returned to the sea because
of economic, legal or personal considerations. Bycatch includes both
discarded and retained incidental catch. In addition to the non-targeted
finfishes and invertebrates, bycatch also involve endangered, threatened
or protected species. Fisheries bycatch has been identified as a primary
driver of population declines in several species of marine mega-fauna such
as elasmobranchs, mammals, seabirds and sea turtles (Lewison et al.,
2004). Minimizing fisheries bycatch is a primary precept of ecosystem
based fisheries management.
