This book was released on 1994 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: In early 1993, investigators collected benthic invertebrates from under the ice cover at nine sites on the Athabasca River. They identified, sorted, and counted the invertebrates to determine the type and abundance of benthic invertebrates at each site. This report describes the study methods and presents the results. The information will be evaluated and compared with similar information previously collected from Athabasca River sites to document changes in benthic invertebrate populations over time and to determine whether those populations have been impacted by man-made discharges to the river.

Download or read book A Survey of the Benthic Macroinvertebrates of the Yellow River written by Scott D. Prill and published by . This book was released on 1981 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: A benthic macroinvertebrate survey was conducted at six sampling locations on the Yellow River in May 1981. Densities at the sampling sites paralleled those of the 1978 survey, with the greatest densities collected in the class B cold water segment of the river. Substantially lower densities were obtained at the other collecting s i t e s in the river. The dominant organisms collected belonged to the family Chironomidae, accounting for approximately 40% of the total density. Several species of mayfly nymphs (i .e. Baetis flavistriga, Ephemerella aurivilli, and Stenonema mediopunctatum) and caddisfly larvae (i .e. Cheumatopsyche sp., Symphitopsyche bifida and S. slossonae) were also common in the collections. The densities, number of taxa and types of benthic macroinvertebrates collected were indicative of generally good, long term water quality in the Yellow River. Two areas of suspected water quality degradation occurred in the Yellow River at Volney and in Hickory Creek, a tributary to Yellow River.
