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.

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).

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.

Available in PDF, EPUB and Kindle. Book excerpt: Report to the federal ministers of Environment and Indian & Northern Affairs, Alberta's Minister of Environmental Protection, and NWT's Minister of Renewable Resources. Summarises the main scientific findings of the Northern River Basins Study, which was established to examine the relationship between industrial, municipal, agricultural, and other development and the Peace, Athabasca, and Slave River basins. Reviews the characteristics of the northern river basins and their peoples, the organisation of the Study, and major findings in the areas of environmental overview, use of aquatic resources, traditional knowledge, flow regulation, fish distribution and habitat, nutrients, dissolved oxygen, contaminants, drinking water, ecosystem health, modelling, human health, and cumulative effects. Recommendations by the Study Board, First Nations, and scientific advisors regarding such issues as basin management, monitoring, research, public participation, and a successor organisation are then presented. Also includes a summary of opinions, suggestions, and recommendations expressed at 17 community workshops held throughout the northern river basins area.

Book excerpt: An important component of the Northern River Basins Study was the original data resulting from the collection and analysis of environmental samples. Samples were collected, stored, and analysed by a number of different agencies, and an inventory of samples obtained by the Study and results data were compiled into a single electronic database to ensure future ease of access to the original data. This report describes the data contained in the database, the methods used to compile the database, the media and the nature of the samples, the collection site, and the data collected. Information is provided on which analyses were conducted on samples as well as the values of various parameters measured for the samples. All the files and the data fields that comprise the database are described in the users' guide in the report appendix.

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.

Hesslein and published by The Study. This book was released on 1996 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: Describes a study of the stable isotope composition of sulphur, carbon, and nitrogen in the tissues of fish from two locations in the Athabasca River and two on the Peace River. Fish species analysed included burbot, walleye, mountain whitefish, northern pike, goldeye, longnose sucker, and lake chub. A set of samples consisting of biofilm, invertebrates, and fish from the upper Athabasca was also analysed. The purpose of the study was to extend the data base on feeding and movement of fish which could be derived from the carbon and sulphur isotope data, and to use the nitrogen isotope data to define the trophic positions of the organisms. Isotope analyses of water samples established the isotope signals of the source of organic matter produced in or carried into the Athabasca by its tributaries so that the dependence of the food chain on those sources could be assessed.
