About the Native Trout Recovery Program

Alberta's Native Trout Recovery Program is a comprehensive, long-term fish conservation initiative aimed at monitoring and recovering populations of native trout and whitefish in the watersheds of the Eastern Slopes.

The Native Recovery Program’s focus is to recover the species through understanding the threats to its survival, through co-ordinated action, and through the support of stakeholders, the public, and multiple levels of government.

The Native Trout Recovery Program is part of an integrated provincial fisheries management approach, which means it is linked to:

  • Westslope cutthroat trout, bull trout and Athabasca rainbow trout recovery planning processes
  • Watercourse Crossings Remediation Program
  • Whirling disease and invasive species management

How the Native Trout Recovery Program works

Many native fish populations in the Eastern Slopes of Alberta have experienced severe declines in abundance and distribution. As a result, several species are now listed provincially and federally as follows:

  • Athabasca rainbow trout – Endangered under the Species at Risk Act (SARA), and Threatened under Alberta’s Wildlife Act.
  • Bull trout – Threatened under Alberta’s Wildlife Act, Saskatchewan-Nelson River populations listed as Threatened under the Species at Risk Act: Western Arctic populations listed as Special Concern.
  • Westslope cutthroat trout – Threatened under both the Species at Risk Act and Alberta’s Wildlife Act.
  • Arctic grayling and mountain whitefish are species that are of conservation concern.

All these species have overlapping ranges within the east slopes. Efforts to recover listed native trout species is expected to benefit all species in overlapping areas.

Threats to Alberta’s native trout

Alberta Environment and Parks has been examining the various negative impacts on native trout populations and the cumulative effects of these impacts. Of the more than 20 such impacts that are caused by human activity, fisheries biologists have identified several that have particularly significant effects:

Habitat: Degradation, destruction and fragmentation of habitats

Harvest: Indirect mortality resulting from catch and release fishing and illegal harvest

Hybridization: interbreeding and competition with non-native trout, and restoration stocking of native trout

A coordinated recovery program for Eastern Slopes fish species at risk, focused on a multi-species approach rather than a single species, is expected to have a higher likelihood of success. An adaptive management approach will be used that will require measurable actions at varying watershed spatial scales and time frames, and will provide be inclusive of additional opportunities for Albertan’s to contribute to species recovery.

How focal watersheds were selected

The Eastern Slopes Fish Management Zones (FMZ) are home to a network of popular sportfishing rivers and waterbodies. It is also an important and popular landscape for industrial and recreational activities. This has placed enormous pressure on local fish populations and habitats, making recovery efforts in the area necessary to ensure populations remain sustainable.

Recovering fish populations is a complex and costly task. Threats limiting the abundance and distribution of fish populations, such as habitat degradation and fragmentation, can accumulate over time and overlap in a particular watershed.

Fisheries management and our stakeholders have developed a cumulative effects framework to understand which threats are most likely limiting fish populations.

Addressing these threats requires coordinated efforts that span entire watersheds within meaningful timeframes. Focusing fish population recovery efforts in a few watersheds using the best available science allows biologists, regulators, industry and stakeholders to work together more effectively and learn how to most efficiently recover fish in the face of multiple concerns. Successful actions are intended to be applied to other watersheds planned for recovery action.

The watersheds being monitored by the Native Trout Recovery Program were selected based on 3 main factors:

Biological factors – how successful recovery efforts can be, based on how degraded the watershed is, and whether or not local fish populations have a reasonable chance of recovery

Economic factors – whether or not government or stakeholder driven fish population restoration work has taken place, is taking place, or will take place in a given watershed

Social factors – a measure of the ability to change attitudes and actions to support sustainable fish populations in the area

Management actions in the Eastern Slopes

Actions will address the key threats limiting bull trout, Westslope cutthroat trout and Athabasca rainbow trout populations, and will include:

  • restoration of degraded habitats
  • angling regulation changes in select habitats
  • mitigation of sediment and phosphorous runoff to improve water quality
  • suppression or removal of non-native
  • fish and other aquatic invasive species
  • restoration stocking
  • addressing threats through implementation of sound land use planning, processes, and practices

Assessment of native trout program results

During the program, the abundance and distribution of fish populations in focal watersheds will be tracked, and local results compared with fish population targets established for each watershed.

All recovery efforts in the selected watersheds will be carefully recorded to determine which actions were successful and which were not. The information and knowledge gained will help address Alberta's ongoing fish management challenges.
