Discards of the Western Mediterranean trawl fleets

We present a quantitative analysis of the composition (commercialized catch and corresponding discard) of trawl catches, in seven ports of the western Mediterranean. Discards are defined here as the fraction of the catch from the haul that is returned to the sea by the fishermen, because it does not...
