| Muestreos realizados en meses lluviosos de los años 2008 y 2009 manifiestan influencia de aguas dulces en la salinidad del Golfo de Guacanayabo, registrándose valores promedios de 34,9 y 33,6 ‰, respectivamente. Elementos no conservativos como el SiO3, el P-PO4- y el N-NH4+ manifiestan una tendencia al incremento a medida que disminuye la salinidad presentándose correlaciones negativas significativas (α<0,05), corroborando la importancia de los escurrimientos fluviales en el aporte de nutrientes. Los bajos coeficientes de correlación denotan otras fuentes de aporte. En comparación con registros anteriores se observan disminuciones en los SiO3, incrementos del P-PO4- y una variabilidad con tendencia ascendente-descendente en los compuestos nitrogenados. |

| The aim of this work was to analyze hydrological condition variations in Cienfuegos’ Bay in 2011 and its possible influence in life cycle and distribution of the green mussel Perna viridis. The hydrological parameters in the bay are described according to the campaigns performed in February, May and November. Samples from two levels (surface and bottom) were taken, in order to get water temperature, salinity and dissolved oxygen. The results show the climatic seasonality influence (dry and rain) both in spatial as well as in vertical distribution of the observed parameters. The mean concentrations of the analyzed hydrological markers were in agreement with the NC 25: 1999 requirements of good quality water for fishing use. The observed hydrological... |
