Description

The Crowsnest River became a provincial priority to understand the impact of whirling disease on rainbow trout populations, prompting a comprehensive study of the watershed in 2019. Results of the study are contained in this report. The objectives of this study were to: determine the spatial distribution, infection prevalence and severity of Mc in the Crowsnest River; measure triactinomyxon density in free-flowing water; characterize oligochaete relative abundance throughout the Crowsnest River; measure the timing and location of optimal water temperatures for parasite development and transmission; and estimate density and age-class structure of juvenile rainbow trout. The Crowsnest River is a high-value sport fishery in southern Alberta.

Description

Alberta’s decontamination protocol helps ensure the proper cleaning of watercraft and other equipment used in water to reduce the spread of aquatic invasive species and fish disease. The revised Decontamination Protocol will better protect Alberta waters by providing clear directions for realistic decontamination methods that can be applied by a wide range of users. It is important to have consistent direction on practices for cleaning of equipment after it has come in contact with water and before moving to different waters.

Description

In August 2017, the Government of Alberta Decontamination Protocol was introduced as a management strategy to reduce the spread of whirling disease and other aquatic invasive species and fish diseases. In 2018 Alberta Environment and Parks began work to expand the decontamination protocols to include industrial operations working in or near water in Alberta. A draft policy and tracking template were developed. This record contains the draft documents and background materials provided to elicit informed public feedback through an online survey and public information sessions during the Fall of 2018.

Description

In August 2016, the first confirmed occurrence of whirling disease in Canada was found in fish from Johnson Lake in Banff National Park and the Bow River Basin. While the disease has no impact on human health, it can severely impact some salmonid fish populations. Alberta Environment and Parks is committed to implementing management strategies to reduce the risk to susceptible fish populations. As a part of this commitment, the Whirling Disease Innovative Research and Learning (WhIRL) Grant Program was created to support research initiatives that will provide novel information on whirling disease in Alberta. A total of $1,000,000 will be allocated in 2018-19 to fund research proposals. This application package provides more information on program eligibility, grant availability, and reporting requirements, and includes the application form.
