| 520 | |a"Seventy-five invertebrate samples (Eckman dredge) taken from depositional areas of the upper Athabasca river were processed. These samples represented eight sites of five replicates each collected in May 1993, and seven sites of five replicates each collected in September 1993. The number of aquatic invertebrates per sample ranged from 40 to 8028 individuals. Invertebrates were more abundant in the fall samples. Oligochaete worms and chironomid larvae were generally the most commonly occurring organisms"--Report summary. |
