The Influence of wetlands and watershed geology on lake chemistry of five remote lakes in Northwestern Ontario
In chapter 1 of this study the relationship between spatial, chemical, and biological factors and their influence on mercury concentration s in walleye were examined. Water, sediment, and fish tissue samples were collected ...
Detecting trends in walleye (Stizostedion v. vitreum, Mitchill) abundance using catch-effort data
Three methods of analyzing catch-effort data were investigated regarding their relationship to walleye abundance: mean CUE, Gini coefficient and the relative frequency of zero CUE (RFZ). Walleye recreational fishery ...
Biology and histopathology of Proteocephalus ambloplitis Liedy, 1887, infecting walleye (Stizostedion vitreum vitreum) and yellow perch (Perea flavescens) in Lake of the Woods, Ontario
Walleye (Stizostedion vitreum vitreum ) and yellow perch (Perea flavescens ) from Lake of the Woods were examined for parenteral Proteocephalus ambloplitis from May to November, 1982 and 1983. One hundred percent of ...
Effects of an episodic removal scheme on a walleye, stizostedion vitreum vitreum, population
A pulse fishing scheme, applied over a three year period (1980 to 1982), deliberately removed 3226 walleye from Henderson Lake, Ontario, causing the stock to collapse. The objective of the removal was not only to seek ...
Annual production and population dynamics of a relatively unexploited walleye, Stizostedion vitreum vitreum (Mitchill 1818), population in Savanne Lake, Ontario
Most studies of the walleye have been conducted on highly exploited populations. Savanne Lake in northwestern Ontario, and having an area of 364.29 ha, was exploited until 1969, whereupon it was designated a fish ...
