dc.descriptionPara caracterizar la biodiversidad de invertebrados bentónicos que componen la fauna asociada a la pesca de camarones en el puerto del Farol de São Thomé, costa norte del estado de Río de Janeiro, se realizaron 11 pescas mensuales en el año 2004 con redes de arrastre de fondo, cuya área de operaciones comprende 3-5 mn desde la línea de costa, entre 22°00’S y 22°20’S. Los datos registrados de cada taxon y/o especie se refieren a la frecuencia de ocurrencia, frecuencia numérica, biomasa, Índice de Importancia Relativa y abundancia. En total se registraron 27 especies de invertebrados bentónicos de Porifera, Cnidaria, Mollusca, Annelida, Crustacea, Echinodermata y Bryozoa. Crustacea fue el más representativo, tanto en número de ejemplares de Petrochirus diogenes, Hepatus pudibundus y Callinectes ornatos, como en biomasa de P. diogenes y H. pudibundus. En términos de frecuencia de ocurrencia en los muestreos, 11 especies (40,7%) fueron constantes; 6 (22,2%) accesorias y 10 (37,0%) accidentales.es-ES
dc.descriptionIn order to characterize the biodiversity of the benthic invertebrate by-catch associated with the shrimp fishery at Farol de São Thomé harbour, northern Rio de Janeiro State, Brazil, in 2004, 11 monthly trawls were conducted using bottom trawl nets between 22°00’S and 22°20’S and from 3 to 5 nm from the shoreline. The analyzed data for each taxon and/or species include frequency of occurrence, numeric frequency, biomass, Index of Relative Importance, and abundance. In total, 27 benthic invertebrate species were recorded, including Porifera, Cnidaria, Mollusca, Annelida, Crustacea, Echinodermata, and Bryozoa. The most representative group was Crustacea, both in number of specimens (Petrochirus diogenes, Hepatus pudibundus, Callinectes ornatus) and in biomass (P. diogenes, H. pudibundus). In terms of the frequency of occurrence in the samples, 11 species (40.7%) were constant, 6 species (22.2%) were accessories, and 10 species (37.0%) were by-catch.en-US
