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.

Book Synopsis Analysis for Liver Mixed Function Oxidase in Fish, Upper Athabasca River, 1992 by : W. Lyle Lockhart
Download or read book Analysis for Liver Mixed Function Oxidase in Fish, Upper Athabasca River, 1992 written by W. Lyle Lockhart and published by . This book was released on 1996 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aquatic fauna of northern Alberta rivers are exposed to contaminants from municipal and industrial sources, including pulp mills. Studies of sub-lethal effects such as increased levels of enzyme activity can indicate an early response to environmental stress in these fauna. This paper reports on a project conducted to examine mixed function oxygenase activity in fish collected from six sites on the upper Athabasca River, upstream and downstream from the Hinton bleached kraft mill. The investigators applied two enzyme assays to fish liver samples collected from mountain whitefish, longnose sucker, northern pike, and white sucker. Enzyme activities were compared with contaminant residue levels and sex steroid hormones reported for the same fish in other related studies. Results presented compare levels of chlorinated dioxin and furan residues in the fish with the site-by-site pattern of enzyme activity.

Download or read book Analyses for Circulating Gonadal Sex Steroids and Gonad Morphology in Fish, Peace, Athabasca and Slave River Basins, September to December, 1994 written by Scott Barrie Brown and published by The Study. This book was released on 1996 with total page 154 pages. Available in PDF, EPUB and Kindle. 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.

Also includes a summary of opinions, suggestions, and recommendations expressed at 17 community workshops held throughout the northern river basins area.
Book Synopsis Analyses of Dehydroretinol, Retinol, Retinyl Palmitate and Tocopherol in Fish, Peace, Athabasca and Slave River Basins, September to December, 1994 by : Scott Barrie Brown
Download or read book Analyses of Dehydroretinol, Retinol, Retinyl Palmitate and Tocopherol in Fish, Peace, Athabasca and Slave River Basins, September to December, 1994 written by Scott Barrie Brown and published by The Study. 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.

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.
