Propranolol is a human pharmaceutical b-blocker that has been detected in municipal wastewater effluents in low concentrations. To assess the potential of this compound to affect fish, Fathead minnow (Pimephales promelas) were exposed for a life cycle in a flow-through system to nominal propranolol concentrations. During the 162-day to 165-day exposure, no significant changes in weights or lengths were seen in Fathead minnows, although the highest concentration of propranolol did cause a 15% decrease in survival of larval and juvenile stage fish compared with controls. At maturity, there were no significant changes in condition factor, liver-somatic index, or secondary sex characteristics in propranolol-exposed male or female fish.

Information regarding processor facilities in British Columbia including location, company name and license tag information. CRIMS is a legacy dataset of BC coastal resource data that was acquired in a systematic and synoptic manner from 1979 and was intermittently updated throughout the years. Resource information was collected in nine study areas using a peer-reviewed provincial Resource Information Standards Committee consisting of DFO Fishery Officers, First Nations, and other subject matter experts. There are currently no plans to update this legacy data.

This high sensitivity aeromagnetic survey was carried out by Goldak Airborne Surveys (Goldak) on behalf of the Geological Survey of Canada (GSC) between January 25th and March 26th, 2011. Aircraft equipment operated included three cesium vapour magnetometers, a GPS real-time and post-corrected differential positioning system, a flight path recovery camera, VHS titling and recording system, as well as radar and barometric altimeters. All data were recorded digitally in GEDAS binary file format. Reference ground equipment included two GEM Systems GSM-19W Overhauser magnetometers and a Novatel 12 channel GPS base station which was set up at the base of operations for differential post-flight corrections.
