Should Maine adopt stricter welfare rules for commercial fish farms?
Animal Outlook, a Washington-based animal welfare nonprofit, has petitioned Maine's Department of Agriculture, Conservation and Forestry to write rules governing the welfare of farmed salmon. The petition was received September 29 and would affect the state's finfish aquaculture industry, including Cooke Aquaculture USA, Maine's largest operation.
Why it matters
Animal Outlook acted after two undercover investigations at Cooke Aquaculture USA's Bingham hatchery, in 2019 and late 2025, found the same practices still ongoing. Because the department's earlier approach relied on Cooke voluntarily improving its practices, the petition asks the state to set enforceable standards instead.
The petition rests on two undercover investigations of Cooke Aquaculture USA's Bingham hatchery, one released in 2019 and one conducted in late 2025, with the later investigation finding the practices documented in 2019 were still ongoing. The Maine department has not yet opened rulemaking, so the petition's welfare claims have not been tested through the state process.
The players
Animal Outlook
A Washington-based animal welfare nonprofit that conducts undercover investigations of farmed animal operations and advocates for welfare regulations.
Cooke Aquaculture USA
The largest finfish aquaculture operation in Maine, holding 24 active permits, and a subsidiary of the New Brunswick-based Cooke Inc.
Conservation Law Foundation
An environmental advocacy organization that filed a Clean Water Act lawsuit against Cooke Aquaculture USA over its Maine operations.
Hannaford
A grocery chain that received a 90-day corrective action plan from Cooke and is a defendant in a consumer deception lawsuit filed in New York.
The details
Maine's Administrative Procedure Act lets citizens petition state agencies to adopt or modify rules, and once enough registered voters sign, the agency must begin the rulemaking process within 60 days. Animal Outlook presented its investigation findings to Hannaford, a grocery chain that received a 90-day corrective action plan from Cooke. A consumer deception lawsuit was filed against Hannaford and Ahold Delhaize USA in New York last month. Separately, a federal judge in Maine ruled in September that a Clean Water Act lawsuit by the Conservation Law Foundation against Cooke Aquaculture USA may proceed.
Timeline
2019: Animal Outlook released undercover video from the Bingham hatchery.
September 29, 2026: The Maine department received Animal Outlook's petition.
Late 2025: Animal Outlook conducted its second Bingham hatchery investigation.
September 2026: A federal judge ruled the Conservation Law Foundation lawsuit against Cooke may proceed.
Later this month: The department expects to begin the rulemaking process.
Health Landscape
The petition shifts the question from whether producers will voluntarily improve welfare toward whether the state will set enforceable standards for farmed salmon. Maine's finfish aquaculture sector is concentrated in a few large operations, so the outcome of this process could shape how regulators approach fish welfare in the region.
If you buy farmed salmon, this story is a reminder that production conditions can vary widely and that welfare and sourcing questions are increasingly visible to shoppers. Readers who want to understand what they are buying can look for labeling and sourcing information and ask retailers about their supplier standards.
The takeaway
The core insight is that a state rulemaking process, not voluntary industry action, is now the venue for setting farmed salmon welfare standards in Maine. Readers who buy farmed fish can ask retailers where their salmon was raised and what welfare standards their suppliers follow.
What happens next
The Maine Department of Agriculture, Conservation and Forestry is expected to begin the rulemaking process later this month, which will determine whether enforceable salmon welfare standards are proposed.
