Sustainable Fish Farming Facts: Did you know?

1. Marine Harvest net strength is regulated by the BC government.

Our provincial government regulates the condition of our fish farm nets. Our nets must be sent to independent land-based facilities that check net condition and strength test these nets to ensure they are above the legal ‘break strength’ limits established by government. Nets are typically used for 12-16 months and cannot be in water for more than 18 consecutive months.

2. Marine Harvest provides habitat compensation for tenures (sites).

We recognize that while a tenure (site) is being farmed, there is a potential impact on the seabed. The allowable impact is determined by provincial regulators. Regular monitoring and testing of the seabed during the growth cycle at the fish farm ensures that any impacts are minimal. As detailed by Fisheries and Oceans Canada (FOC), habitat compensation is provided by Marine Harvest Canada in the region close to the farm. This compensation is primarily based around habitat improvements for fish within sub-tidal areas. Marine Harvest Canada has provided habitat by means of eel grass transplanting in the Klemtu area as well as artificial reef construction in the Kyuquot and Broughton Archipelago areas.

3. Marine Harvest Canada hatchery facilities use the latest technology.

Marine Harvest freshwater hatcheries have invested in ‘recirculation’ systems. To minimize the amount of freshwater removed from local water tables, our hatcheries use the latest equipment that enables us to re-use up to 95% of the water in the system.

4. Marine Harvest farms use ‘green’ power to raise salmon.

Tidal power, like wind and solar, is a ‘green’ power. Our net pens are kept clean to allow the fresh, cold waters of the Pacific Ocean to flush through and provide oxygen to our salmon. As the concern surrounding global warming focuses on consumption of fossil fuels, we are proud of the fact that it takes minimal fossil fuels to raise our salmon. We continue to research other ‘green’ energy sources to help power our farm accommodation.

5. Marine Harvest Canada is transparent.

Since 2003, Marine Harvest Canada has posted data on its website for the public to see how it manages its farms. On the ‘Sustainability’ section of this website, we post environmental data such as salinity, oxygen levels and temperatures from the waters adjacent to our farm sites. In that same year we started posting sea lice data from our saltwater farm sites so the public can see how a combination of good husbandry and management, biological, and medicinal control can ensure sea lice levels on our fish farms are kept to a minimum.

6. Marine Harvest supports many local salmon enhancement projects.

Because growing salmon is our business, we have much to offer local salmon enhancement groups by way of knowledge and equipment. To view a list of larger salmon enhancement projects that Marine Harvest Canada has been involved in, please visit our ‘Sustainability‘ page.
