Bull Trout Gamete Collection and In-Situ Fertilization

CLIENT: Department of Fisheries and Oceans Canada

As part of the Federal recovery strategy for Bull Trout, an at-risk species, AJM Fisheries Biologists collaborated with the Ontario and Prairies/Arctic Region of the Department of Fisheries and Oceans (DFO) to deliver on an innovative research project exploring the thermal tolerances of the threatened species. AJM was engaged by DFO’s Freshwater Institute to support project planning leading up to the collection of gametes (egg and milt) from a spawning population of Bull Trout in southern Alberta. AJM Biologists then led field crews (including DFO Biologists) in the safe and effective capture (and eventual release) of multiple adult fish from an adfluvial spawning population. Once captured, adult Bull Trout were processed by AJM Biologists for the collection and in-situ fertilization of eggs and milt. Post-collection and fertilization, gametes were prepared for immediate air transport to incubation and rearing facilities in Winnipeg. After hatching, juvenile Bull Trout will be reared by DFO Research Biologists and tested for temperature tolerances. Resulting information will be important to help understand the potential threat of rising water temperatures on Alberta’s Bull Trout populations.

Bleriot Ferry Rehabilitation Project

Jamac Painting & Sandblasting Ltd. (Jamac) retained AJM to provide environmental consulting for the Bleriot Ferry Rehabilitation Project near Munson, AB in 2023. Critical deliverables were to include:

• Environmental Construction Operations (ECO) Plan;

• Bird Management Plan (BMP), including a Wildlife Survey and Sweep of the area; and

• Weed Survey and Weed Infestation map.

AJM crafted an ECO plan compliant with current laws, regulations, permits, and the ECO Plan Framework. It covered all environmental aspects identified by the Environmental Risk Assessment, including Clubroot and Whirling Disease control methods, a Temporary Erosion and Sediment Control Plan, and a Bird Management Plan (BMP). The plan, once reviewed and revised in response to the Project administrator's feedback, included a Clubroot Management Plan adhering to Alberta Agriculture standards and a Whirling Disease protocol based on AEP guidelines.

Pipeline Construction Monitoring - Foothills West Path Delivery (Turner Valley, Longview & Lundreck)

AJM was contracted by TC Energy in 2023 to provide environmental monitoring support for the construction of the Turner Valley, Longview, and Lundbreck sections of the Foothills West Path Delivery natural gas pipeline system in southwestern Alberta.

The scope of work provided by AJM included:

Early season raptor surveys to follow Restricted Activity Period (RAP) timing;
Pre-construction migratory bird nest sweeps;
Amphibian mitigation guidance and salvages;
Mountain Goat and Bighorn Sheep surveys and mitigation on Lundbreck; and
Assisting Environmental Inspectors with implementation of Environmental Protection Plans.

AJM assisted TC Energy in complying with the Migratory Birds Convention Act, the Alberta Wildlife Act, and Species at Risk Act. AJM implemented mitigations for many migratory bird species including two species listed under the Species at Risk Act (SARA); the olive-sided flycatcher (Contopus cooperi) and bobolink (Dolichonyx oryzivorus). AJM provided environmental support to support pipeline development while providing appropriate mitigations to meet regulatory requirements. Additionally, AJM aided TC Energy of implementation of the Environmental Protection Plan developed for this pipeline project. This project was a Canada Energy Regulator (CER) regulated project.
