(1982)The effect of large scale exploitation of walleye Stizostedion vitreum vitreum on the boreal percid community of Henderson Lake, northwestern Ontario, was studied from 1979 to 1981. Investigations centered on the two major ... -
Population dynamics of an exploited population of Orconectes virilis in Northwestern Ontario
(1987)Exploitation of northern stocks of the crayfish Orconectes virilis (Hagen) produced significant alterations in several population parameters. High fishing efforts increased per capita fecundity, young-of-year (YOY) ... -
Production ecology of the amphipod Hyalella azteca (Saussure) in a Northern Ontario lake
(1982)Annual production of the amphipod Hyalella azteca was estimated in the upper littoral zone of Dock Lake, Ontario, over a 2 year period (1980-1981). Population density (negligible below 1 meter) differed among the three ... -
Pulse fishing of a walleye population : response, recovery and management implications
(1997)The response of the Henderson Lake boreal fish community to a large scale exploitation of walleye was studied. The pulse fishery removed approximately 89 percent (3226) of adult walleye (1980-82) from Henderson lake ... -
The 96-hr LC50 and uptake of sodium tellurite in goldfish (Carrasius auratus)
(1992)There is no information regarding toxicity of tellurium in fish. This research used goldfish (Carassius auratus) as an animal model, and sodium tellurite ( Na2Te03) as the form of tellurium to tested. Acute 96-hr LC50 ...
