The Haida Nation is seeking an injunction to stop the herring fishery off the coast of Haida Gwaii.
The Department of Fisheries and Oceans say herring stocks have rebounded to the point where a commercial fishery can be supported.
But the Haida Nation disagrees, and are in court in Vancouver asking a judge to stop the fishery.
Kim Olsen is the president of the United Fishermen and Allied Workers Union.
He has written an open letter in support of keeping the fishery closed, and asking union members to stay away from specific areas.
He says it’s time commercial fishermen work with First Nations to ensure a sustainable fishery.
Olsen says he gives more creedance to the First Nations than DFO scientists since it’s the First Nation’s who are on the ground.
