Seasonal Nearshore Distributions Of Fishes In A Piedmont Section Of The James River, Virginia, Eugene George Maurakis
Master's Theses
The seasonal nearshore distributions of 17 species of fishes were determined in natural and artificially heated areas in a 9.6 km stretch of the Piedmont section of the James River, Virginia from July, 1973 to June, 1974. Analyses of the seasonal distributions were based on abundance and percent frequency of occurrence data. The maximum abundance and percent occurrence of ten of the 17 species of fishes in natural temperature areas occurred in early autumn. Deviations from this pattern included Notropis analostanus, equally abundant throughout the year, and Lepisosteus osseus, Notropis amoenus, Notropis ardens, Notropis rubellus, Catostomus commersoni and Lepomis macrochirus, …

These studies were concerned with the development of methods to assist investigators of wildlife population research. Specifically they involve the description of (1) A device which enables an investigator to mark deer at medium range using specially modified darts fired by conventional tranquilizer rifles, (2) Construction of infrared viewers and light sources using surplus equipment and (3) Studies to develop a method of making permanent deer dental impressions under field conditions.
