Recurring Welfare Concerns at Cooke Aquaculture: A Pattern of Industry Scrutiny

The intersection of corporate accountability and animal welfare remains a focal point for advocacy groups and regulators alike. A recurring pattern has emerged within the aquaculture industry: following undercover investigations into hatchery conditions, companies often issue formal apologies and commit to operational reforms, only to face subsequent allegations of similar welfare failures years later. This cycle raises significant questions regarding the efficacy of self-regulation and the oversight of large-scale seafood production.

The 2019 Investigation and Subsequent Response

In 2019, the animal protection nonprofit Animal Outlook conducted a covert investigation into a salmon hatchery in Maine operated by Cooke Aquaculture. An investigator, Erin Wing, documented several practices that drew immediate concern, including the culling of diseased fish through physical impact against tank walls and instances of overcrowding. Following the release of the footage, CEO Glenn Cooke issued a public apology, stating that the company placed high value on animal welfare standards and would work to improve best practices. The Maine Department of Agriculture subsequently reviewed the facility, resulting in a commitment from the company to retrain staff and update management plans, which led to no formal charges being filed.

Evidence of Ongoing Welfare Issues in 2025

By 2025, Animal Outlook initiated a follow-up investigation at the same Maine facility. The findings, as reported by the organization, suggested that despite previous commitments, welfare challenges persisted. The second investigation documented 133 instances of what the group characterized as improper handling and killing methods, including the use of metal rods for culling and the suffocation of fish. Additional observations included evidence of bacterial and fungal infections, which can be indicators of poor water quality, as well as mass fish mortalities.

Cooke Aquaculture has acknowledged the 2025 investigation, stating that it takes animal welfare seriously and is currently reviewing the footage. The company noted that it intends to take disciplinary measures against employees who failed to follow established company policy.

Industry Oversight and Environmental Impact

The investigation also highlighted concerns beyond immediate animal welfare. Reports from the facility indicated that escape prevention protocols, specifically the use of screens on waste discharge pipes, were not consistently maintained. The Atlantic Salmon Federation has expressed concern regarding these lapses, noting that the escape of farmed salmon into the Kennebec River—a site of restoration efforts for endangered wild populations—can contribute to genetic pollution and population decline.

Cooke Aquaculture maintains certification from Best Aquaculture Practices (BAP), a program designed to verify ethical farm-raised seafood standards. BAP has confirmed that an investigation into the facility is currently underway. Meanwhile, the Maine Department of Agriculture, Conservation and Forestry has confirmed it is conducting its own animal welfare investigation in response to the latest findings.

Key Takeaways: The Challenge of Accountability

• The Pattern of Reform: Advocacy groups frequently observe a cycle where companies pledge reforms after an exposé, yet follow-up investigations often reveal a continuation of previous welfare issues.
• Systemic Risks: Experts in fish welfare suggest that high-density farming environments inherently lead to challenges in maintaining animal health and welfare, regardless of individual employee actions.
• Regulatory Oversight: The lack of comprehensive federal animal welfare laws specifically covering farm-raised fish leaves much of the industry reliant on internal policies and third-party certifications.
• Environmental Consequences: Beyond animal welfare, the maintenance of hatchery infrastructure is vital to preventing farmed fish from entering local ecosystems, where they may negatively impact wild salmon populations.

Looking Ahead

The case of Cooke Aquaculture serves as a case study in the limitations of voluntary corporate reform. As regulatory bodies in Maine evaluate the most recent evidence, the broader conversation regarding the standards for industrial aquaculture continues. For consumers and policymakers, the recurring nature of these incidents underscores the demand for more rigorous, transparent and enforceable oversight in the animal agriculture and aquaculture sectors.
