Abstract

In the present study, landings by an artisanal fishing boat which operates with bottom longline were monitored from July, 2002 to February, 2005. Sharks were found to belong to three families, four genus and nine species, distributed over a catch of 857 specimens of Carcharhinus acronotus, C. falciformis, C. limbatus, C. porosus, Ginglymostoma cirratum, Rhizoprionodon lalandii, R. porosus, Sphyrna lewini and S. mokarran. The species of genus Rhizoprionodon were the most frequent in the landings, showing great importance in artisanal fisheries using small longlines, and all species, except for G. cirratum, are commercially exploited. The catch of C. falciformis, C. limbatus. and Sphyrna spp. was composed mainly of newborns and juvenile specimens, that of R. porosus consists of specimens of all the lengths, with greater incidence in size classes near the estimate of the first sexual maturity suggested by literature, there being observed the presence of pregnant females of a few species.
