A survey of the ichthyoplankton inhabiting the waters adjacent to the proposed Perryman power plant site on the Bush River was conducted from 31 March to 13 September 1984. The results of the spring 1984 sampling showed that yellow perch (Perca flavescens) larvae were often abundant, reaching densities as high as 2,920/100 cu m. Comparison of the data with that from other ichthyoplankton surveys conducted in the Bush River suggests that the number of yellow perch larvae varied greatly among years. Abundance of white perch and clupeids varied less among years. Sampling of nearshore-shallow and deeper channel habitats revealed significant spatial differences in abundances of certain species.
