Black redhorse larval and juvenile habitat was characterized in the Grand River, Ontario from June to September 2007-2012.
Sulphur Springs
Several cold water sulphur springs flow into tributaries of the Welland River on the Niagara Peninsula. Sulphur spring water temperature
Brook Trout Population in an Urban Creek
In response to concerns regarding planned development in the area, Biotactic began monitoring water temperatures and conducted a survey of Brook Trout population size
Fish Rescue and Salvage Operations
Biotactic regularly performs fish rescue and salvage operations, using boat or backpack electrofishing to capture, remove and relocate fish from areas prior to in-water construction activities.
Sulphur Springs: Chemical Barriers to Fish Movement
Several cold water sulphur springs flow into tributaries of the Welland River on the Niagara Peninsula. Sulphur spring water temperature
Electrofishing Surveys to Determine Fish Community Biomass
Biotactic established twenty-two long term monitoring sites (66 sampling subsections) across the Saugeen River watershed within which annual biomass electrofishing surveys are performed to monitor the change in the fish community as a function of the removal of the Truax dam in Walkerton, Ontario, as part of a fisheries offset and compensation project.
Black Redhorse Habitat Preferences
We have been working in conjunction with Fisheries and Oceans Canada to study egg development, early life history
Port Hope Area Initiative Fish Rescue
Prior to and during in-water remediation, Biotactic uses boat electrofishing in the inner harbour in Lake Ontario to remove, relocate, and rescue a variety of fish species.
Lake Niapenco Sport Fish Population Estimates
The Niagara Peninsula Conservation Authority (NPCA) contracted Biotactic to conduct a fish community and population study at the Binbrook Conservation Area, (Lake Niapenco), Binbrook, Ontario. The main objective of the project was to perform
Brown Trout in the Kananaskis River
We used radio-telemetry to investigate detailed movement and summer habitat of brown trout Salmo trutta (size range 157 – 488 mm TL, n = 18) in the Kananaskis River, Alberta. Flows in the Kananaskis River respond to pulsed daily discharge from an upstream hydroelectric generating facility (range 0.15 – 25 m3.s-1). Wetted area available for brown trout doubled during periods of high flow. Fluctuating river levels did not appear to influence the degree to which brown trout moved within the study site. However, there was evidence that brown trout used cover and pools more as discharge increased.
