Deadstock Disposal Fact Sheet

Managing fish mortalities responsibly is a key part of running a sustainable aquaculture operation. While Ontario’s regulations don’t explicitly cover fish, producers are still expected to follow practices that protect the environment, animal health, and public safety.

We’ve put together a Deadstock Disposal Fact Sheet that outlines practical, compliant, and environmentally sound options, including:
✅ Rendering & hauler pickup
✅ On-site burial (with setback & soil guidelines)
✅ Composting (a top choice when managed properly)
✅ Planning for both routine & emergency mortalities

The fact sheet also highlights what regulations do apply, and how fish farmers can demonstrate due diligence in the absence of species-specific rules.
