The Gulf of Ana Maria is located in the southeast Cuban platform and is one of the most important regions for fisheries in the country. Taking into account that marine primary production defines the areas and yields of fishery production, we develop a habitability index that quantifies the environmental suitability for phytoplankton assemblage development. The index considers light and limiting nutrient as the main environmental factors governing the phytoplankton primary production in the Gulf of Ana Maria. We considered a function of radiation described by a photosynthesis model and function of nutrient described by a eutrophication index. Quantitative estimates of habitability were made in nine stations at 1:00 PM and 4:00 PM for a typical day of October, in order to match with the available field data. Solar irradiation at sea surface was calculated by using the tropospheric ultraviolet and visible computational code TUV4.6, and we derived the data of attenuation coefficient of light from Secchi depth data. Besides, we used nutrient concentration of soluble reactive phosphorus (limiting nutrient). We obtained the first optical classification of the waters of the Gulf of Ana Maria, with a dominance of coastal water C5. It was found an intermediate potential (~50%) for phytoplankton development in the Gulf of Ana Maria, which is mainly limited by nutrients rather than by light. Further refinements in both the index and data collection are expected to reach more accurate conclusions. |
