Contributions to crustacean bycatch from urugavian lobster Metanephrops rubellus fisheries in southeastern coast of Brazil

Abstract

 Studies on crustacean bycatch from Norway lobster (Metanephrops rubellus) fisheries between parallels 22° and 26°S (from Rio de Janeiro to Paraná States in Brazil), from depths of 60 to 140 meters, based on 73 landings carried out from 2000 to 2007, conducted to the identification of nine new species in relation to those listed in SEVERINO-RODRIGUES et al. (2007). This new list increases in 19.2% the set of crustacean species of bycatch fisheries of M. rubellus, enhancing the knowledge on biodiversity from landings of part of the fleet in São Paulo State that captures this lobster, highlighting that landings of commercial fisheries constitute an important source of information. Although the samples obtained from this kind of capture do not present the accuracy of those collected from scientific cruises, they can be more constant and embracing, thus offering relevant data on temporal occurrence and spatial distribution and contributing to the knowledge of the biology and ecology of the species.
