Descripción
An important ark clam (Arca zebra) artisanal fishery takes place in the east region of Venezuela. Besides the target species, trawling extracts a significant bycatch of several mollusk species including the gastropod Voluta musica, a threatened species according to the Ven ezuelan Red List of Endangered Species. In this paper we evaluate: 1) the composition of mollusk species in the bycatch, 2) the number of individuals of V. musica caught as bycatch and, 3) the abundance and size structure of the exploited populati on. Each fishing night, about 27,830 m2 are trawled by each boat extracting on the average 607 kg of A. zebra meat and 19 kg of V. musica (whole shelled animal). This fishery activity potentially captures ~30,000 kg of ark clam meat and 922 kg of V. musica in one week (~95 snails/fishing night/boat). The size structure of the V. musica population at the ark clam bed is significantly smaller than in other nearby sites not impacted by trawling fishing activities. Non-targeted species extracted in the bycatch but consumed by the local inhabitants include the gastropods Chicoreus brevifrons, Phyllonotus margaritensis, P. pomum, Fasciolaria tulipa, Strombus pugilis, a few Trochidae species, and the bivalves Pinctada imbricata, Spondylus americanus, Anadara florid ana, A . notabilis, and Trachicardium muricatum. Individuals of V. musica along with several invertebrates are discarded. We recommend that V. musica should not be neglected as a conservation target, and despite that A. zebra fisheries are considered “artisanal”, that more strict regulations should be established on it.
La pesca artesanal de la almeja arca (Arca zebra) es una de las pesquerías de mayor importancia en el oriente de Venezuela. En esta pesquería se capturan incidentalmente varias especies de moluscos, incluyendo el gasterópodo Voluta musica, considerada amenazada según el Libro Rojo de la Fauna Venezolana. En este trabajo se evalúa: 1) la composición de especies de moluscos en la captura incidental, 2) el número de individuos de V. musica capturados como pesca incidental y 3) la estructura de tallas y abundancia de la población explotada. En cada faena de pesca se arrastran 27.830 m 2 por cada barco, extrayendo en promedio 607 kg de A. zebra (sin concha) y 19 kg de V. musica (con concha). La flota completa captura ~30.000 kg de A. zebra y 922 kg de V. musica en una semana (~95 caracoles/noche de pesca/barco). La estructura de tallas de la población de V. musica en el banco de A. zebra es significativamente menor comparada con sitios cercanos no afectados por la pesca de arrastre. Otras especies capturadas incidentalmente son consumidas por los habitantes loca les e incluyen los gasterópodos Chicoreus brevifrons, Phyllonotus margaritensis, P. pomum, Fasciolaria tulipa, Strombus pugilis, y unas pocas especies de Trochidae, bivalvos Pinctada imbricata, Spondylus americanus, Anadara floridana, A . notabilis, Trachicardium muricatum. Los individuos de V. musica y otros invertebrados son desechados completamente. V. musica debe ser considerada como objeto de conservación, y a pesar que la captura de A. zebra es considerada "artesanal", se deberían establecer regulaciones más estrictas sobre esta especie.
