Overview and annual report
The Alberta Provincial Stocking program supplies approximately 240 lakes with hatchery-reared trout to:
- provide recreational angling opportunities
- reduce angling pressure on natural fish populations
- maintain or enhance fish populations
These stockings create angling opportunities within the province that entice anglers to explore and contribute to the economic expansion of Alberta’s fisheries.
The provincial fish-stocking program adds substantial value to the sportfishing industry, contributing an estimated $100 million annually to provincial revenue. For a report on annual stocking activities, see:
The following trout species are stocked within the province:
- Brook Trout
- Brown Trout
- Cutthroat Trout
- Rainbow Trout
- Tiger Trout
Approximately 2.1 million trout (average size 17.5 cm or 65 grams each) are stocked each season into Alberta’s waterbodies for recreational angling purposes.
Arctic grayling are cultured every four to five years for stocking purposes.
The walleye program incubates green eggs that are collected from fish in the wild and stocked as three-day-old fry. Additionally, fingerlings are grown to a larger size (5 cm and 12 cm) and stocked into designated waterbodies.
Tiger trout are a sterile hybrid species that are created using brown trout eggs and brook trout milt. The provincial stocking goal is to produce approximately 50,000 23 cm tiger trout each fall.
Stocked Lakes and the Alberta Guide to Sportfishing Regulations
The Alberta Guide to Sportfishing Regulations includes a list of lakes and reservoirs that are identified as regularly stocked lakes. These waterbodies:
- allow the use of bait
- are open year-round
- have possession limits that support the province-wide maximum possession limit

Notice: Information on advisories, corrections and closures are available.

Fish Mortality–Summer and Winter Kill
Summer and winter kill occurs when large numbers of fish die due to a lack of dissolved oxygen. Winter kill can occur in many of Alberta's frequently stocked waterbodies. For a more detailed description regarding summer and winter kill and the lakes affected in Alberta visit the link
Important! Contact Alberta Environment and Parks (AEP) if you see large numbers of dead fish in any Alberta waterbody. To find contact information for the office nearest you, visit the Alberta.ca website at:
Provincial Fish Hatcheries
Allison Brood Trout Station
The Allison Brood Trout Station is the source of eyed Brook, Brown, Rainbow, Cutthroat and Tiger Trout eggs for the province’s production hatcheries in Cold Lake and Calgary. This facility houses 2,000 – 3,000 broodfish and has the capacity to house 20,000 brood recruits
Raven Brood Trout Station
The Raven Brood Trout Station started as an experimental rearing site in 1926 and became an official operation in the fall of 1937. Raven Brood Station grows 50,000 production trout for recreational stocking and produces approximately 500,000 eyed eggs annually for the rearing facilities.
Cold Lake Fish Hatchery
The Cold Lake Fish Hatchery opened in 1987 and draws water from Cold Lake at a depth of 30m. The hatchery rears and stocks approximately 900,000 Tiger, Rainbow, Brook and Brown Trout per year. The Cold Lake Fish Hatchery is the only provincial hatchery that is designed to raise walleye.
Sam Livingston Fish Hatchery
The Sam Livingston Fish Hatchery is one of the largest indoor hatcheries in North America. Rainbow Trout, Brook, Brown Trout, Cutthroat Trout are raised from eggs in this facility and stocked into lakes across the province.
Alberta's Brood Trout Stations
The Alberta Government owns and operates 4 fish hatcheries. Two of the hatcheries function as brood trout stations housing adult fish reared to produce the eggs required for spawning various trout species to stock select waterbodies across the province.
There are three different strains of rainbow trout, one strain each of brown, brook and cutthroat trout. The brook and brown trout cross to create the tiger trout as well.
The brood stations need to ensure they have adequate adults on hand to produce required eggs. Proper crossing of the various strains of trout is vital to prevent inbreeding of our trout and to achieve high survival of fertilized eggs.
Allison Creek Brood Trout Station Mobile Quarantine Unit
Allison Creek Brood Trout Station operates a mobile quarantine trailer unit that can incubate wild eggs collected from trout populations in streams or rivers in Alberta. The quarantine facility is a self-contained, 100% re-use water system. This unit is ideal for incubating small numbers of wild fish eggs to assist in restoration of native fish.
Alberta fisheries biologists determine the wild fish collection site and the number of eggs to incubate to eye-up inside the quarantine facility. Eyed eggs return to designated streams and placed into Instream Incubators that utilize stream water and allow the fry to emerge from the eggs and swim up into the stream. This greatly increases survival of the fry and allows reintroduction into barren or low population streams.
Triploiding of Stock Trout
Alberta Fish Culture triploids fertilized trout eggs to ensure that trout in most stocked waters for recreational fishing, are sterile (unable to reproduce). The stocking of triploid trout ensures that the genetic integrity of wild trout populations is not compromised.
The triploid procedure involves placing the fertilized eggs in a chamber that is pressurized. Timing is critical and varies with species. The proper timing and pressure will result in the fish having three chromosomes (3N) instead of the normal two (2N) rendering them sterile.
