Diferencias espaciales y estacionales en el contenido de nutrientes, demanda de oxígeno y potencial redox en sedimentos bajo una instalación de producción acuícola en jaulas

Abstract

En zonas templadas, como el Mediterráneo occidental, los impactos ambientales resultantes de la sedimentación de materia orgánica particulada en el fondo marino bajo las instalaciones de una explotación acuícola parecen estar determinados por factores como la producción, la batimetría, la época del año y la distancia a las dependencias. En este trabajo se evalúan las concentraciones de materia orgánica y de nutrientes y el potencial redox en los sedimentos de los fondos situados bajo las jaulas flotantes de una producción acuícola; los resultados permiten observar que en el transcurso de los meses de verano se producen aumentos en la concentración de nutrientes y en la demanda de oxígeno y un descenso del potencial redox.

Most reviews on environmental impacts of fish farming have emphasised that the most widely known effect is benthic enrichment beneath the sea farms. Marine fish farming is increasing rapidly in the Mediterranean coastal zone. It is characterised by clear water with high transparency, microtidal, oligotrophic and nutrient-poor sediments. The present paper discusses the results obtained in the analysis of the sediments beneath and surrounding the sea farm.
