Production, mortality, and power plant entrainment of larval yellow perch in Western Lake Erie. Final report, 1975-78
This study assessed impacts of the Monroe Power Plant upon the yellow perch population of Western Lake Erie caused by entrainment and impingement of larvae and older fishes in the plant's open cycle cooling system in 1975-76. Data analyzed in the study were collected by the Michigan Department of Natural Resources, the Center for Lake Erie Area Research of the Ohio State University, and the Institute of Water Research of Michigan State University. Estimates of total numbers of perch larvae entrained, total perch production, the natural mortality rate of perch, and the percentage of perch production that was entrained by the Monroe Power Plant were obtained for 1975-76. A numerical model was developed which incorporates several population parameters including entrainment and impingement losses, and natural mortality rates for larvae, young-of-year and juveniles, and fishing mortality rates.
