Effect of rate of water discharge on phytoplankton in Claytor Lake, Virginia
Claytor Lake, Virginia, an 1820 ha main stern hydroelectric reservoir, was studied for one year to determine the effect of water discharge on reservoir phytoplankton. Number/liter, areal units/liter, average cell size, and chlorophyll a content were used as measures of phytoplankton abundance. Rate …

Effects of landlocked alewife introduction on white bass and walleye populations, Claytor Lake, Virginia
… to the alewife. Changes in the fish fauna of Claytor Lake between 1950 and 1971 are discussed. Based on the two rotenone samples taken during this study, the standing crop of fishes in Claytor Lake is below that of most other reservoirs.

Genetic Characterization of Intermixed Walleye Stocks in Claytor Lake and the Upper New River, Virginia
… different walleye stocks have been stocked in Claytor Lake, Virginia. The increasing importance of the walleye fishery led to interest in clarifying key unknowns regarding the biology of the New River walleye stock. A radio telemetry study and genetic evaluation of present-day stocks led to …

Genetic evaluation of walleye (Stizostedion vitreum vitreum) stock structure and recruitment in Claytor Lake, Virginia
… several geographic areas have been stocked in Claytor Lake since 1940. Fish presently in the reservoir may have originated from the stocking of Kansas, Nebraska, or Pennsylvania walleyes, or may possibly be descended from a native New River walleye strain. Recent stockings (1974, 1975, 1977, …

Habitat Use, Movements, and Exploitation of Striped Bass and Hybrid Striped Bass in Claytor Lake, Virginia
… saxatilis x M. chrysops (HSB) was evaluated in Claytor Lake, Virginia. This study assessed: 1) habitat use versus habitat availability for STB and HSB; 2) seasonal movement patterns, movement rates, and emigration rates of STB and HSB; and 3) angler catch rates of STB and HSB in Claytor Lake. In …

Reproduction and early life history of a landlocked population of alewife (Alosa pseudoharencus) in Claytor Lake, Virginia
Alewives in Claytor Lake matured at age I at 160 mm TL. Fecundity of gravid females increased with age and length, ranging from 17,307 eggs at age I to 37,147 eggs at age III. The majority of alewife spawning was concentrated in littoral areas of a large embayment. Spawning period was protracted …

Assessment of the Response of Piscivorous Sportfishes to the Establishment of Gizzard Shad in Claytor Lake, Virginia
Gizzard shad were illegally introduced to Claytor Lake in the late 1980s and soon established a thriving population. This study assessed 1) the degree to which gizzard shad were utilized by piscivores (pelagic - striped bass Morone saxatilis, hybrid striped bass M. chrysops x M. saxatilis, and …
