Discards composition from Iberian trawl fleets
Fisheries discards are an issue of general management and societal concern. This study presents the first analysis and characterization of discards composition from Iberian trawl fleets using Portuguese and Spanish onboard sampling programme data from 2004 to 2012. The allocation of observed trips i...

Fisheries discards are an issue of general management and societal concern. This study presents the first analysis and characterization of discards composition from Iberian trawl fleets using Portuguese and Spanish onboard sampling programme data from 2004 to 2012.

In general, results indicate that Iberian discard rates are highly variable being low in some specific fisheries, but moderate to high in most trips.
