Spatio temporal variation in octocoral assemblages along a water quality gradient in the northwestern region of Cuba

Rivers are the main sources of nutrients to coastal zones. Therefore, the effects of water quality degradation onoctocoral assemblages and their relationship with microbiological and physical-chemical variables were determinedin reefs close to river basins in the northwestern region of Cuba. The evaluations were carried out in 1m2 frames at a depth of 10 m in 13 fore reefs. The highest concentrations of the microbiological variables andhydrochemicals and the lowest horizontal visibility in the water column were detected in the reefs near the riverbasins. The lowest richness, diversity and octocoral density were related to higher concentrations of fecal coliform,total coliform and fecal streptococcal bacteria, sediment accumulation on the bottom and lower visibility.The structure of the octocoral assemblages varied significantly between reefs due to fecal organic pollution.Water quality deterioration in the reefs near the river basins has negatively affected the octocoral assemblages.
