Abstract

The research boat used in this experiment, named Sinuelo and owned by the Fisheries and Aquaculture Department of UFRPE/FADURPE, employed different types of bottom longline, during July and August 2002, off Pernambuco State. Several demersal species of broad distribution and high commercial value were caught during the experiment. The spurdog shark (Squalus spp.) was the most abundant species (64.2% of the total catch, CPUE of 2.07 ind./100 hooks). Among teleosteans, the golden tilefish (Lopholatilus vilarii) was the dominant species (33.3% of the group). The snowy grouper (Epinephelus niveatus) and the greater amberjack (Seriola dumerili) showed higher catch rates from 200 m to 300 meters. The mutton snapper (Lutjanus analis) and the coney were caught only up to 200 meters. The highest CPUE was recorded from 400 m to 500 meters. The vertical bottom longline fishing gear showed good results, being easy to operate, and was successfully employed in the Sinuelo, a small boat, typical of the artisanal fleet.
