The major invertebrate was Penaeus duorarum and the major fish Lagodon rhomboides. Poplulation levels of nearly all species suddenly increased to high levels and decreased as rapidly to former low levels. Heaviest populations occurred in spring (4.9 gm/m2 in May) with a secondary high in fall (3.5 gm/m2 in mid-September and October). Lowest populations occurred in summer (0.8 gm/m2 in mid-July to mid-August) and winter (0.46 gm/m2 in January). Total population densities were correlated best with water level, but summer and winter minimums coincided with many adverse factors. The fauna was similar to that of Florida west coast bays where the major habitat type is the same.seasonalityaquatic plantsmarine organismsturtle grassThalassia testudinumplant populationsaquatic communitiesaquatic animalsArticle
