  • licence to collect fish for aquaculture
  • licence to stock fish

The province regulates the culture of fish to minimize the risk of ecological damage resulting from aquaculture activities, such as fish escapes, which can alter aquatic ecosystems and native fish populations. These regulations protect Ontario fisheries by preventing:

  • the unauthorized introduction of fish into new waters

Licence to collect fish for aquaculture purposes

Aquaculturists may apply for this licence to collect fish or eggs from the wild to help develop broodstock.

Licence to collect fish:

  • lowers the risk of genetic contamination
  • reduces the introduction and transfer of infectious fish disease
  • protects fish species during collection and vulnerable stages of their life cycle

To get a licence to collect fish for aquaculture purposes, you need to:

  • have no connection or outflow to natural waters
  • contain water from surface run-off, natural springs, ground water or water pumped from a stream or lake

You should contact your local ministry district office to confirm waters as “artificial.”
