This book was released on 1995 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: Presents a study that collected and prepared fish from 23 sites along the Peace, Athabasca, and Slave river drainages in order to conduct physical, physiological, contaminant, and biophysical analyses. The primary fish species targeted for collection and analysis was burbot, used as a sentinel species for monitoring contaminants in northern waters because of its wide distribution, ease of catching, place at the top of the aquatic food chain, and large liver which can bioaccumulate organic compounds. Other species collected were northern pike, longnose sucker, and flathead chub. Specific analyses included gross pathology, metals, liver mixed function oxygenase induction, sex steroids and gonad morphology, retinols, metallothioneins, and basic life history information. Fish were also examined externally and internally for gross pathological abnormalities and deformities. Appendices contain descriptions of fish collection and handling protocols, as well as detailed data.

This book was released on 1996 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metallothioneins are a family of proteins whose synthesis in animal organs and tissues can be induced by exposure to heavy metals. This report describes metallothionein concentrations in fish collected from northern Alberta rivers and tributaries. The analyses incorporate results from examination of kidney, liver, intestine, and gill tissues of burbot, longnose sucker, northern pike, and flathead chub. Results are organised into reference (upstream locations and tributaries receiving no inputs from pulp mills), near-field (within 100 kilometres downstream from a pulp mill), and far-field (over 100 kilometres downstream).

This book was released on 1997 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Presents the findings of various field and laboratory projects that studied fish distribution, movement, habitat utilization, and gross pathology in the northern Alberta river basins. Begins with a description of the river basins and related water bodies, a list of fish species found, and an overview of fish distribution and relative abundance in the mainstem rivers. This is followed by a synthesis of available information on movements of fish through space and time, as collected from fish tagging and radio telemetry studies. Movements of individual fish are also described (spawning movements and movements to summer feeding and winter habitats). Finally, critical fish habitats (spawning, feeding, and overwintering) are noted, food chain studies are summarized, and responses of fish to changes in water quality (including pathological manifestations) are reviewed.

This book was released on 1996 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: Adverse effects of low environmental oxygen on fish reproduction represents a distinct possibility in the Athabasca and Peace drainages. Species spawning in late fall and winter, such as burbot, would be the most likely to be impacted by low dissolved oxygen (DO). This report describes a study whose objective was to define the temporal changes in reproductive hormones, identify changes in blood electrolytes, haemoglobin, hematocrit, and blood oxygen content, and evaluate the viability of eggs and sperm for burbot during the period of sexual development under normal and hypoxic conditions. The results evaluate the potential of realistic winter water temperatures and hypoxic conditions to impair reproductive performance and induce stress in spawning burbot in the Northern River Basins Study area.

Book excerpt: The objective of this study was to examine reproductive indices in fish collected from the Peace, Athabasca, and Slave rivers and their major tributaries. The fish species targeted for collection and analyses were burbot, northern pike, longnose sucker, and flathead chub. Biochemical and histological approaches included analysing levels of gonadal sex steroid hormones, measuring gonad morphology, and estimating fecundity. Results are organised in to reference (upstream locations and tributaries receiving no inputs from pulp mills), near-field (within 100 kilometres downstream from a pulp mill source), and far-field (over 100 kilometres downstream) groups.

Available in PDF, EPUB and Kindle. Book excerpt: Summarises and interprets the analytical results for various organic chlorine contaminants in fish collected from northern Alberta river systems and also compares the observed organochlorine levels with the regulatory limits set by Health Canada. Major organochlorine groups detected were polychlorinated biphenyls, DDT- and chlordane-related compounds, toxaphene, and chlorinated phenolics. Background information is included on the properties, uses, toxicity, sources, environmental fate and transport, and bioaccumulation of the contaminants studied. Results are given for such fish species as mountain whitefish, burbot, northern pike, and longnose sucker, and for concentrations observed at locations downstream and upstream of known sources of contaminants.

This book was released on 1996 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vitamin A (retinoids) and E (tocopherol) have received increasing attention as possible indicators of exposure to a variety of environmental pollutants. This study examines vitamin A and E indices in fish collected from northern Alberta rivers, where fish are exposed to a variety of industrial effluents, as part of a multi-faceted study into altered fish physiological function due to environmental contaminants. The fish species targeted for collection were burbot, northern pike, and longnose sucker. The investigators conducted biochemical analyses in the laboratory to determine levels of retinol, dehydroretinol, retinyl palmitate (three storage forms of vitamin A), beta carotene (precursor form of vitamin A), and tocopherol in fish livers. For comparison, results are organised into reference (upstream locations and tributaries receiving no input from pulp mills), near-field (within 100 kilometres downstream from a pulp mill source), and far-field (over 100 kilometres downstream) groups, where sample sizes were adequate.

Also evaluates the impacts of nutrient loading on river chemistry, assesses the response of riverine biota to nutrient loading from pulp mill and municipal effluents, quantifies nutrient responses of benthic biota, and investigates interactions between nutrients and contaminants in pulp mill effluents on food webs. The findings are used to assess the state of aquatic ecosystem health and to develop scientific and management recommendations for the northern river basins.

Book excerpt: Describes a project designed to obtain and record existing ecological knowledge of northern Alberta river basins as recorded in archival documents. The documents researched and recorded in a database for this project included journals of fur traders, the Royal Northwest Mounted Police, settlers, and travellers; archived government records such as those from the Geological Survey of Canada and the Dept. of Indian and Northern Affairs; and information from the Hudson Bay Company archives. The database consists of 233 records which may be searched for specific ecological information ranging from river flooding to fish harvest, fur trade and weather records, geological and environmental descriptions, and illness and death of both humans and animals.
