Abstract
Lake George is a 28,000 acre meso-oligotrophic lake located in the southeast portion of the Adirondack Park, New York, U.S. Gill netting was carried out in conjunction with the New York State Department of Environmental Conservation at 25 sites to determine interbasin differences of yellow perch, Perca flavescens and lake trout, Salvelinus namaycush, in Lake George, New York. Health condition, growth and diet were analyzed for 267 yellow perch and 132 lake trout. The length-weight relationship exhibited significant differences amongst the basins for condition constants (b). The yellow perch from the North basin exhibited allometric growth, while those in the South and Narrows displayed isometric growth. Lake trout from the North basin exhibited allometric growth, while those in the South and Narrows displayed isometric growth. Relative weights were found to be below the general target range and had significant differences among the basins for yellow perch. Lake trout were also below the target range but exhibited no significant differences between the basins.
