AI-Assisted Salmon Counting from Underwater Fence Camera Footage
Ecology
What it collects
- Underwater video footage collected at fish fence monitoring sites across rivers and streams, provided by the Science Branch — Stock Assessment Lab. The footage captures fish passing through fence structures and contains no personal information.

What it is for
This system uses computer vision AI to automatically detect and count salmon by species from underwater video footage collected at fish fence monitoring sites. It is being developed by Fisheries and Oceans Canada to reduce the manual effort required by scientists who currently review hours of footage by hand. No personal information is involved, and the AI use is disclosed to users. The system is currently under development and not yet in production.
What it collects and what happens to it
Data taken in
- Underwater video footage collected at fish fence monitoring sites across rivers and streams, provided by the Science Branch — Stock Assessment Lab. The footage captures fish passing through fence structures and contains no personal information.
Processing
- The system uses advanced computer vision techniques to detect and count salmon species from underwater video footage captured at fish fence monitoring structures installed across rivers and streams.
What it does
- The system processes underwater video footage to detect and count salmon by species — converting raw video frames into structured species counts. Government of Canada employees (GC employees) review the resulting data, placing human oversight on downstream stock assessment decisions.
- Beyond raw detection, the system classifies detected fish by species and produces counts — a classification and scoring function over structured detections. Results are reviewed by GC scientists who make final stock assessment determinations.
Outputs
- Species-level salmon counts derived from automated analysis of fence camera footage — structured count data indicating the number of salmon detected per species at each monitoring site. This output replaces manual tally records previously produced by human reviewers.
Run by
- Fisheries and Oceans Canada is the federal department responsible for safeguarding Canadian waters and aquatic resources. DFO deploys and operates PSSIFence to support its fish stock assessment obligations.

How to read the colours
Can it identify you?
- Anonymized data
- Data about people with the link to who is broken. Stripped of identifiers, blurred, aggregated, or noised so this system can’t reasonably tie a record back to an individual.
- Pseudonymous data
- Each person’s data is tied to a token (hash, ID, template) that lets this system recognise the same person across events, but the token itself doesn’t reveal a name. Reidentification is possible with extra information.
- Identifiable data
- The data either contains a direct identifier (name, address, account name, recognisable face or voice, plate number) or carries a token this system uses to look up legal identity during processing.
Who completes the loop?
- Human decides
- This mode suggests; a person decides what to do next. The AI is always advisory — a human is in the loop on every decision. Example: a triage tool ranks cases for a clinician who chooses which to see first.
- Human executes
- This mode decides; a person carries out the result. Example: an optimizer plans the day’s trash-collection routes, and drivers run them.
- Autonomous
- This mode decides and acts on its own. No person reviews each decision or carries out the resulting action.
Definitions from the DTPR standard. Amber is about your data, violet about who decides. The fuller the shape and the deeper the colour, the more identifying the data or the less a person is involved.

Your rights
- Right to Algorithmic TransparencyThe use of AI in this system is disclosed to users. GC employees who use the outputs of PSSIFence are informed that an AI system is assisting in fish counting. For further information, contact Fisheries and Oceans Canada through official departmental channels.
- Right to Be Informed of AI UseAI use is disclosed to the GC employees who are the primary users of this system. The register entry confirms 'AI use disclosed to users: Y'. As the system does not process personal information, this right applies primarily to internal government users rather than members of the public.
Risks and safeguards
- Reputational harmInaccurate species classification or miscounts could lead to erroneous stock assessment conclusions, potentially affecting fisheries management decisions and the credibility of DFO's scientific outputs.Safeguard: The system is currently in development; GC employees serve as primary users who review AI-generated counts before they inform official assessments, maintaining human oversight. The system is intended to improve accuracy over current manual methods.
