| Abstract: | (Contribution to the biological study of blue shark (Prionace glauca) incidental catch by the
Spanish surface longline fisheries for swordfish in the western Mediterranean).
Blue shark (Prionace glauca) bycatches in the Spanish surface longline fisheries in the
Mediterranean targeting swordfish (Xiphias gladius) from 1999 to 2001 represented 2% of the
total catch. Information from onboard observers during 861 fishing sets in 26 longliners
indicated that the highest catches were made in area 4-35000 (Alboran Sea) which represents
75.6% of the total observed catch of blue shark. The observed CPUE are from 5.5 to 34.1
kg/1000 hooks. Mean size at capture (LJFL) was 141.6 cm (SD=35.88). The proportion of
females from the total was 0.5. |
