Analysis of swordfish surface longline fishery in Andalusia, Spain
Highlights
The Spanish surface longline fleet has been historically targeting swordfish (Xiphias gladius) but large pelagic sharks are caught as by-catch
Andalusian longline fleet comprises a total of 52 vessels, most of them operating in the Atlantic Ocean and the Mediterranean Sea
Blue and shorfin mako sharks in Andalusia account for 2.82% of the total landings in 2015 and were worth 9,300,563.35 € (5.8%), according to the statistics provided by Andalusia fisheries administrations
Summary
The Spanish surface longline fleet has been historically targeting swordfish (Xiphias gladius) but large pelagic sharks are caught as by-catch. The most frequent by-catch species are the blue shark (Prionace glauca) and the shortfin mako (Isurus oxyrinchus), both in the Atlantic Ocean and the Mediterranean Sea. These three species represent more than 90% of the total landings (Mejuto et al, 2009).
