    Description: The evaluation of the possible environmental changes due to the anthropic impacts that have happened in the last years in this scenario and the redefinition of areas that suffer affectations were carried up. Any environmental alteration of this ecosystem, either of natural or human origin, can have an important economic and social repercussion. According to the proposed chemical and biological indexes, the waters of the Gulf of Batabanó presented mesotrophic conditions with tendency to the eutrofization in four fundamental areas. In the silts of the Gulf the values of organic carbon and sulphidric acid were characteristic of sediments with high concentrations of organic matter. In the coastal sector N, was determinate high concentrations of sulphidric acid and heavy metals, which indicates elevated levels of antrophic affectation. The waters of the reefs of the Gulf showed mesotrophic conditions, while the silts were considered little affected, according to the chemical and biological indexes proposed in this work.

    Description: El Archipiélago Sabana – Camagüey es una de las regiones más estudiadas de la plataforma marina cubana. Entre los años 2001-2005 se evaluaron los contenidos de nitratos más nitrito, amonio, nitrógeno total, fósforo inorgánico y fósforo total, y se establecieron las relaciones nitrógeno total inorgánico & fósforo inorgánico N/P y nitrógeno total & fósforo total NT/PT, en las bahías de Cárdenas, Santa Clara Oeste, Puerto de Sagua la Grande, San Juan de los Remedios, Buenavista, Los Perros, Jigüey y La Gloria. El amonio fue la principal fuente de nitrógeno inorgánico y los contenidos de nitrógeno orgánico evidenciaron el predominio de los procesos de biosíntesis. Las relaciones N/P y NT/PT fueron superiores a 16:1 en la mayoría de las bahías estudiadas, indicando que el fósforo fue restrictivo para los productores primarios excepto en la bahía de San Juan de los Remedios.
    Description: The Sabana – Camagüey Archipelago is one of the studied regions more of the Cuban marine shelf. the bays Cárdenas, Santa Clara Oeste, Puerto de Sagua la Grande, San Juan de los Remedios, Buenavista, Los Perros, Jigüey and La Gloria were evaluated between years 2001 and 2005 the contents of nitrate more nitrito, ammonium, total nitrogen, inorganic phosphorus and total phosphorus and established the rates inorganic total nitrogen & inorganic phosphorus N/P and total nitrogen & total phosphorus NT/PT. The most important source inorganic nitrogen was the ammonium and the organic nitrogen contents confirmed the predominance of the biosynthesis processes. In the majority of the studied bays the rates N/P and NT/PT were higher than 16:1, the primary producers were limiting for phosphorus except in San Juan de los Remedios bay.
