Its purpose is to investigate the probable causes of trends in the abundance of certain species, especially recent declines, as they relate to the overall health of the ecosystem. For some species, confining the discussion to a geographic scale as small as a single estuary may give false impression of its population. But the primary question here is that of the health of the estuarine system, not the health of a particular species.estuariesecosystemsspeciesfinfish fisheriesshellfishalligatorsplanktonTechnical Report
