Policies & Practices

We know the BC Coast is precious to its residents. As residents ourselves, we are committed to protecting the marine environment now and into the future. We work closely with scientists, veterinarians, environmental experts, and other salmon farmers so that we operate at consistently high standards that go above and beyond our regulatory requirements.


Salmon farming is a tightly regulated industry. We work with governmental agencies such as Fisheries and Oceans Canada (DFO) and the BC Ministry of Environment to ensure BC is a world-leader in its standards for aquaculture.

Many of the regulatory requirements to hold an aquaculture licence relate to ongoing testing, monitoring and reporting. We regularly assess our fish for parasites such as sea lice as well as monitor the environment around our operations to ensure we are having a minimal impact on the local marine life.

One of the key aspects that we report on is the presence of naturally occurring sea lice. When the number of motile female sea lice reaches 3 per fish, DFO mandates that action be initiated to control sea lice numbers. In spring months when juvenile wild salmon are outmigrated from their natal streams, monitoring and treatment for sea lice in our farm salmon is enhanced (denoted in solid versus dashed green lines in the graphs below). The following links provide a summary of the sea lice data (by region) that was collected and reported to DFO from 2012-present. As per DFO protocols, sea lice numbers are not reported during events such as fish transfers, harvesting, or when farms are not holding fish.

Operational Policies

Salmon farming has come a long way since its early days on the BC Coast. As it has grown and evolved, so too have our operational policies, which ensure our fish are raised in an environmentally and economically sustainable way.


Grieg Seafood has been awarded the Best Aquaculture Practices certification by the Global Aquaculture Alliance — the leading standards-setting organization for aquaculture seafood. The Global Aquaculture Alliance’s review process involved an audit of Grieg’s social responsibility, food safety, animal welfare, traceability processes and systems, and a visit to its farms. Best Aquaculture Practices certification standards for salmon farms incorporates ongoing guidelines and quantitative criteria for veterinary care, nets, and feed content and ratios.


The safety of our fish is paramount for our farmers. As there are many naturally occurring fish viruses that can impact the health and well-being of our fish, bio-security measures are in place at all farm sites. Visitors are asked to follow these measures while on our farms.

Farm Visits

Salmon aquaculture is a unique and modern way of farming. We utilize tried and true methods combined with cutting edge scientific and technological tools to protect our fish and the surrounding environment. We encourage those who are interested in learning more to take advantage of the annual Farm Tour Program, run through the BC Salmon Farmers Association: www.salmonfarmers.org/farm-tours.
