Food Habits, Prey Selectivity And Food Resource Partitioning Of A Community Of Fishes On The Outer Continental Shelf, George R. Sedberry Iii
Food Habits, Prey Selectivity And Food Resource Partitioning Of A Community Of Fishes On The Outer Continental Shelf, George R. Sedberry Iii
Dissertations, Theses, and Masters Projects
The demersal fish community of the outer continental shelf in the Middle Atlantic Bight consists of resident species, seasonal species with boreal affinities, and seasonal species with warm temperature affinities. Dominant demersal fishes of the outer continental shelf feed primarily on macrobenthic invertebrates, which persist in dense, stable communities. Some dominant predators also feed heavily on fishes, cephalopods, and planktonic invertebrates, at least seasonally. Food habits of the fishes change seasonally, especially at the species level. Food habits of fishes also change considerably with size, with most predators showing distinct feeding stanzas separated by a marked change in feeding strategy. …

Morphological, Histological, And Physiological Aspects Of Assimilation In Larval Spot, Leiostomus Xanthurus Lacepede, John Jeffrey Govoni
Morphological, Histological, And Physiological Aspects Of Assimilation In Larval Spot, Leiostomus Xanthurus Lacepede, John Jeffrey Govoni
Dissertations, Theses, and Masters Projects
In view of questions concerning the digestive and assimilative abilities of larval marine fishes, the changes in these processes with development, and their relationship with starvation-induced mortality; this study has three objectives: (1) to examine the morphological and histological development of the alimentary canal and associated structures of larval spot, Leiostomus xanthurus (Pisces: Sciaenidae); (2) to assess short-term carbon assimilation in discrete age cohorts of larval spot; and (3) to relate any changes in assimilation to development. The alimentary canal and associated structures of larval spot from hatching through transformation (metamorphosis) were examined using light microscopy. These findings were related …
The Effects Of Chlorinated Sea Water On The Blue Crab, Callinectes Sapidus, Chae E. Laird
The Effects Of Chlorinated Sea Water On The Blue Crab, Callinectes Sapidus, Chae E. Laird
Dissertations, Theses, and Masters Projects
The effects of chlorinated sea water on the blue crab, Callinectes sapidus Rathbun, were evaluated through measurements of acute toxicity, serum constituents (protein, total ninhydrin positive substances, chloride, osmotic, sodium, potassium, calcium, and magnesium concentrations), oxygen consumption and ventilation rates in whole crabs, and oxygen consumption of excised gills. Histological examination of gills was also performed. The 96-hr LC50 for female blue crabs exposed to chlorinated sea water at 21�C and 14('0)/00 was 0.86 mgCl(,2)/l CIO (chlorine induced oxidants). The value for males under similar conditions was 0.84 mgCl(,2)/l CIO. Mortality was uncommon below 0.61 mgCl(,2)/l, but reached 100% with …
Resource Use By Amphipoda (Crustacea: Peracarida) On The Outer Continental Shelf Of The Middle Atlantic Bight: Implications To Community Structure, Linda C. Schaffner

Benthic communities on the outer continental shelf of the Middle Atlantic Bight are characterized by abundant populations of amphipods in the families Ampeliscidae and Corophiidae. Members of these families occupy tubes at or near the sediment surface and, thus, potentially compete with each other for spatial and trophic resources. This study examines the spatial, temporal and trophic resource use of six numerically dominant species in these families as a means of assessing the relative importance of competition as a structuring force in outer shelf benthic communities.
