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 ...
Distribution of fishes in the Thunder Bay area of northwestern Ontario since deglaciation, with special reference to the darters (Genus Etheostoma) and the Sibley Peninsula
(1991)
The prevailing theory explaining fish distribution in the western Lake
Superior basin states that recolonization was from south to north following the
retreating ice margins. Postulated access to post glacial Lake Superior ...
Interference of aquatic plants associated with wild rice (Zizania palustril L.)
(1995)
The objective of this thesis was to determine the interference
potential of aquatic plants to wild rice (Zizania palustris L. )
through field and laboratory studies. Three companion papers
describe the influence of ...
Role of aquatic macrophytes in trophic status of Northwestern Ontario lakes
(1993)
This research focusses on the development, refinement, and assessment of regional trophic status
models for lakes of northwestern Ontario. Two companion papers describe the application of
image analysis of aerial photographs ...
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 ...
Density, depth distribution and richness of emerging insects (Diptera: Chironomidae) before and after experimental watershed deforestation
(1999)
The primary objective o f this study was to document changes in Chironomidae
density, depth distribution, and taxon richness, associated with experimental upland and
riparian deforestation of L42, a small boreal forest ...
Specific binding sites for [H Dexamethasone and [H17B-Estradiol [17-Beta (Greek symbol)] in the hypothalamus of juvenile rainbow trout, Oncorhynchus mykiss
(1999)
In bony fishes such as the rainbow trout, Oncorhynchus mykiss, glucocorticoid (GC) and
estrogenic hormones are associated with a variety of physiological functions. Most notable are
effects of GCs which allow the animal ...
Physiology of development, germination and ubiquitination in pea seeds
(1993)
The development of entire seeds and axes of Pisum sativum L. cv. Spring
was followed between 18 and 47 days after flowering, in terms of changes in fresh
weight, dry weight, water content, protein level and chlorophyll ...
