A First Nations hereditary chief is protesting the Marine Harvest salmon farm on Swanson Island off the east coast of Vancouver Island.

Chief Ernest Alfred and a group of First Nations say they will continue to peacefully occupy the operation until the province cancels the farms licence and forces it to leave their territory.

A news release from the Sea Shepherd Conservation Society says the group is concerned that salmon farms are harming wild fish by spreading disease and pests.

Alfred says wild salmon runs are collapsing, leaving his community without food, and farmed fish and transport vessels have no place in the region.
