Yellowstone Np Report
Abstract
Distribution, abundance, and habitat utilization of the Virgin Spinedace, Lepidomeda mollispinis nnllispinis, is being studied at 12 stations in and near Zion National Park, Utah, and one at Lytle Ranch, Utah. Fish are being collected by seining and electroshocking, and associated habitat parameters of water depth, current velocity, substrate type, cover, and water conductivity are being measured. Suitability index curves for spinedace are being developed for depth, substrate, and current velocity.
