Assessing and addressing the re-eutrophication of Lake Erie: Central basin hypoxia
article Relieving phosphorus loading is a key management tool for controlling Lake Erie eutrophication. During the 1960s and 1970s, increased phosphorus inputs degraded water quality and reducedExpand
LIFE AFTER DEATH IN LAKE ERIE: NUTRIENT CONTROLS DRIVE FISH SPECIES RICHNESS, REHABILITATION
Support for this work was provided by (1) Federal Aid in Sport Fish Restoration F-69-P (to R. A. Stein), administered jointly by the U.S. Fish and Wildlife Service and ODNR-ODW, (2) the Department ofExpand
Piscivory by Walleyes and Yellow Perch in Western Lake Erie
TLDR
Diet overlap was greatest among walleye age groups (0, 1, and 2-and-older) and least between walleyes and yellow perch, indicating thatyellow perch were the more opportunistic feeders. Expand
Walleye egg deposition and survival on reefs in Western Lake Erie (USA)
Lake Erie walleye (Stizostedion vitreum) populations exhibit wide fluctuations in recruitment (Hatch et al. 1987). Interannual variation in the abundance and first year survival of walleye cohorts isExpand
First‐Year Growth, Recruitment, and Maturity of Walleyes in Western Lake Erie
TLDR
A regression model for walleye recruitment in western Lake Erie considered factors such as first-year growth, size of the spawning stock, the rate at which the lake warmed during the spring, and abundance of gizzard shad Dorosoma cepedianum to support contention that mature females needed adequate lipid reserves during the winter to spawn the following spring.

FUZZY COGNITIVE MAPPING AS A TOOL TO DEFINE MANAGEMENT OBJECTIVES FOR COMPLEX ECOSYSTEMS
TLDR
This work presents the steps involved in constructing an FCM of an ecosystem, interpreting FCM output using multivariate statistics, and portraying the information in an easily communicated fashion, and offers recommendations for increasing the efficiency of the model-development and interpretation process.

Response of Yellow Perch to Changes in the Benthic Invertebrate Community of Western Lake Erie
Abstract In the western basin of Lake Erie, benthic invertebrate abundance and community composition have changed dramatically over the past five decades, as have abundance and growth of yellow perchExpand
Modeling sources of variation for growth and predatory demand of Lake Erie walleye (Stizostedion vitreum), 1986-1995
TLDR
In simulations combining effects of population structure, temperature, and age-specific consumption, migratory walleye grew most rapidly, taking advantage of temperature-related growth peaks in both basins. Expand
Reduction in recruitment of white bass in Lake Erie after invasion of white perch
TLDR
The growth, maturity, and fecundity of adults during the period 1981–1997 were compared with the same characteristics found by earlier studies and it was found that establishment of the white perch Morone americana population in Lake Erie during the early 1980s led to reduced survival of the early life stages of white bass.

Changes in Prey Fish Populations in Western Lake Erie, 1969–88, as Related to Walleye, Stizostedion vitreum, Predation
Relative abundance of the total prey fish community in the western basin of Lake Erie varied little from 1969 to 1988, but species composition changed significantly. Soft-rayed fishes such as emera...
