DATA-LIMITED MIXED FISHERIES TARGETING DATA-POOR SPECIES: THE ARTISANAL PURSE-SEINE FLEET IN THE CANARY ISLANDS
In waters off The Canary Islands, small pelagic fish are targeted by an artisanal purse seine fleet. This fishery has been monitored within the EU Data Collection Framework since 2013. The status assessment of the most important commercial species (i.e. Scomber colias, Trachurus spp, Sardinella spp...
