Striped bass Morone saxatilis were collected from Lake Anna, a thermally enriched Virginia reservoir, and Smith Mountain Lake, an ambient-temperature Virginia reservoir, and their ovaries were compared for differences in Vitellolipid and Vitelloprotein. Habitat analyses indicated summer temperatures and dissolved oxygen concentrations were stressful to striped bass in Lake Anna and nonstressful to striped bass in Smith Mountain Lake. Summer ovary weights, condition factors, and body lengths and weights were significantly lower for Lake Anna striped bass than for Smith Mountain Lake fish. Total vitellolipid and total vitelloprotein concentrations did not differ significantly between the two samples, but concentrations of vitellotriglyceride and other esters and of certain component vitelloproteins were significantly greater in ovaries of Smith Mountain Lake striped bass. These data indicate bioenergetic stresses in Lake Anna did not significantly affect the quantity of vitellolipids and viteiloproteins sequestered by Lake Anna striped bass, but did significantly affect vitellolipid and Vitelloprotein composition.
