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.
Download or read book Fish Collections Peace Athabasca and Slave River Basins September to December 1994 written by Toni-Lynne Jacobson and published by . 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.
