Primeros datos sobre la meagafauna bentónica de la Ría de Pontevedra: Peces demersales y crustáceos decápodos (Brachyura)

Abstract

El presente trabajo se centra en el estudio inicial del megabentos de la Ría de Ponrevedra , con vistas a establecer los parámetros básicos determinantes de la abundancia y distribución de los peces demersales y crustáceos. Los datos obtenidos se comparan con los correspondientes a otras rías, incidiendo asimismo en el posible efecto de los efluentes industriales. Los patrones de distribución observados en otras rías (influencia de las bateas, profundidad, características del sustrato e influencia de las aguas dulces), se mantienen en la Ría de Pontevedra. Se detectan sin embargo ciertas diferencias más manifiestas en el caso de los crustáceos, presumiblemente en relación con una menor movilidad que la que presentan los peces, y verse así más afectados por cualquier alteración del medio. La zona interna de la ría se caracteriza por la abundancia de especies propias de zonas fluctuantes, y que soportan considerables variaciones de salinidad y bajos niveles de oxígeno disuelto, como son los crustáceos Carcinus maenas y MacroPipus arcuatus y los peces Pomatoschistus minutus y Gobius niger. La clara dominancia en toda la ría del decápodo Inacbus dorsettensis , especie característica de zonas fangosas en otras rías, puede estar en relación con los altos valores de materia orgánica en el sedimento citados para la Ría de Pontevedra. Por ello creemos que los efluentes industriales constituyen un factor más que incide sobre la abundancia y distribución de la comunidad. Versión del editor
