The main objective of this study is to provide valuable baseline data, which are essential for monitoring and tracking changes in the lake.
Rainbow Trout Migration Patterns in the Saugeen River Watershed
The Truax Dam was removed in August 2019. Future post-removal phases of this study will provide data that will be compared to baseline information to assess the impact of the removal of this barrier on the Saugeen River rainbow trout population.
Rainbow Trout Passage at a Nature-Like Fishway, Beaver River, Ontario
Rainbow Trout (Oncorhynchus mykiss) were monitored over two consecutive vernal migration periods at a nature-like fishway on the Beaver River, Ontario to assess attraction efficiency, passage
Rainbow Trout Passage at the Maple Hill Dam
Passage efficiency of radiotagged rainbow trout at the Maple Hill fishway was 20 %. Based on our professional opinion, coupled with radiotelemetric data and underwater videography, it is highly likely that the measured
Northern Pike Telemetry and Passage Monitoring
Radio transmitters were surgically implanted in the body cavity of ten northern pike between 502 mm TL and 752 mm TL in March 2003 to assess fish passage at the Port Davidson Weir. Fish were released downstream from the fish bypass channel, and tracking began immediately using mobile
Effects of Increased Silt Load
Rock bass (Ambloplites rupestris) are a widespread centrarchid species with both riverine and lacustrine populations. After precipitation evens, rivers often carry elevated silt loads, where as lakes generally remain
Physiological Telemetry
Conventional techniques for implanting electrodes into axial swimming musculature of fish are reviewed.
Fish Movement at the Springbank Dam: Before-After Study
The City of London and the Upper Thames River Conservation Authority contracted Biotactic Incorporated to design and conduct a study to collect baseline data related to fish movement
Blue Sucker Tracking
In October 2004 we implanted thirty Texas state endangered blue suckers (Cycleptus elongatus) with radio transmitters that we (Bio-West, Austin and Biotactic) monitored continuously
Fish Passage in Brazil
In November 2012, and again in 2019 we assisted our very good friends at Simbiota in Southern Brazil with some very exciting fish surgery,
