    Effects of an episodic removal scheme on a walleye, stizostedion vitreum vitreum, population 

    Reid, David M. (1985)
    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 ...
