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 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.

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.

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.

Book Synopsis Accumulation of Fish Mixed Function Oxygenase Inducers by Semipermeable Membrane Devices in River Water and Effluents, Athabasca River, August and September, 1994 by : Joanne Louise Parrott
Download or read book Accumulation of Fish Mixed Function Oxygenase Inducers by Semipermeable Membrane Devices in River Water and Effluents, Athabasca River, August and September, 1994 written by Joanne Louise Parrott and published by . This book was released on 1996 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reports on a study that used semipermeable membrane devices (SPMDs) to identify industrial effluents along the Athabasca River system that induce mixed function oxygenase (MFO) activity in fish cell lines. These SPMDs provided samples of known exposure time in effluents and river waters by simultaneously sampling the effluent stream and the river upstream and downstream of the mixing zone at each site. The investigators deployed the SPMDs for two weeks at one major town and five industrial wastewater sites (four pulp mills and one oil sands facility) on the Athabasca, and at one pulp mill on the Lesser Slave River. They tested SPMD extracts for MFO activity using cell culture techniques in top minnow (Poeciliopsis lucida) hepatoma cells. Results presented include comparisons of MFO induction potency between different sampling sites and between type of effluent source.

Download or read book Dissolved Oxygen Requirements for Fish of the Peace, Athabasca and Slave River Basins written by M. A. Giles and published by The Study. 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.

This book was released on 1996 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: Examines the diet, food web, and seasonal changes in structure of the fish community of the lower Slave River as revealed in sampling studies using gill nets, seines, and set lines used June-December 1994 and May-August 1995. Diet was determined by direct examination and classification of dietary items for the 18 fish species collected, using the percent occurrence method. Catch per unit effort was also calculated for the species. Discussion of results includes summaries of fish life cycles and identification of potential risks of biomagnification effects.
