Elasmobranch Landings for the Portuguese Commercial Fishery From 1986 to 2001
Portuguese commercial elasmobranch landings were analyzed for the period 1986–2001. An average of 5,169 (± 795 t) were landed yearly, representing 18 families, 29 genera, and 34 confirmed species. However, annual landings for the fishery generally decreased over time, with a corresponding increase in price per kilogram. The most important group, Raja spp., accounted for 33% of the landings or 26,916 t.They were followed by Centroscymnus coelolepis, Scyliorhinus spp., Centrophorus granulosus, and Centrophorus squamosus (accounting for 12%, 12%, 11%, and 9% of the landings, respectively). In the absence of CPUE data, the comparative trends of landings and price were employed as an indicator of the “status” of specific elasmobranch species. Raja spp., Centrophorus granulosus, Mustelus spp., Torpedo spp., and Squatinidae displayed indications of possible overexploitation, and they merit the focus of future research.
