Abstract

ACUNA, Enzo; VILLARROEL, Juan C.  and  GRAU, Rodrigo. FISHES ASSOCIATED WITH THE FISHERY OF SWORDFISH (XIPHIAS GLADIUS LINNAEUS). Gayana (Concepc.) [online]. 2002, vol.66, n.2, pp.263-267. ISSN 0717-652X.  http://dx.doi.org/10.4067/S0717-65382002000200025.

The information on the by-catch captured during fishing operations of two vessels (one artisanal and other industrial) is analyzed, between November 2000 and September 2001. Both vessels operated inside and outside of the Chilean Exclusive Economic Zone (EEZ) between 24°07'S and 37°13'S. The species from each fishing haul were identified, counted and measured in their length. The presence of six species of chondrichthyan fishes (five sharks and one ray) and 10 teleosts fishes was recorded, including the target species. The percentage by number of the species found in the by-catch shows a high percentage of chondrichthyan fishes (72%) with respect to the swordfish (21%), being the blue shark (Prionace glauca) most abundant species in the catches with a 59% of the total number of fish caught

Keywords : by-catch; swordfish; longline; sharks; conservation; management.
