Discards of small-scale fisheries (SSF) in the Suez Gulf, Red Sea, Egypt

Abstract

Discarding is one of the most top challenges in fisheries management, because it is a waste of resources, a source of uncertainty for fisheries scientists and decision-makers, and a factor impacting biodiversity and community (Alverson et al., 1994). The capture of immature individuals and non-marketable species, on the other hand, may raise the catch composition's discard ratio. Because trammel netting is widely considered as a nonlethal capture technique, trammel nets are frequently used when assessing populations of rare fishes (Hubert, 1996). Three layers of multifilament netting constitute a trammel net, with a small-mesh inner netting layer between two layers with largest mesh.Gill-nets are often used in small-scale fisheries because they require little in the way of equipment and are successful at catching fish populations that are widely dispersed (Reis & Pawson, 1992).
