It is known that the encrusting and excavating Caribbean sponge Cliona delitrix may increase its abundance near sources of sewage. To ascertain whether its current conspicuousness in leeward reefs of San Andrés Island (SW Caribbean, Colombia) is related to organic pollution from local raw sewage discharges, quantitative data on density and cover of this sponge and other benthic components was obtained from belt and line transects at seven stations along the shallow (5-10 m deep) terrace. Coral mucus was sampled to quantify Escherichia coli bacteria, as an approximate indicator of sewage plume influence on benthic biota. A negative multiplicative regression between amount of E. coli in coral mucus and distance from the main raw sewage outlet demonstrated... |

Los vertidos de aguas residuales domésticas a las aguas marinas sin tratamiento apropiado constituyen una fuente importante de contaminación a la Región del Gran Caribe (RGC) y representa una amenaza para el desarrollo sostenible. El trabajo muestra un Estudio de Línea Base sobre el manejo de las aguas residuales domésticas en ecosistemas marino-costeros contaminados hot spots de Colombia (Bahía de Cartagena), Jamaica (Bahía de Kingston), Nicaragua (Bahía de Bluefields), Trinidad y Tobago (Golfo de Paria), Venezuela (Golfo de Cariaco), Guyana (Georgetown) y Suriname (Paramaribo) con un predominio de tanques sépticos, seguido del uso de letrinas y el alcantarillado sanitario, y se elaboran las bases para el diseño y planificación de planes de manejo... |
