What is “troll-caught” salmon?
Trollers are small boats that fish by hook and line. Fishing this way means that there is little impact on the environment and minimal by-catch, or non-targeted catch. Troll-caught salmon are caught one at a time, cleaned by hand and packed in ice. Careful individual handling results in top quality and superb flavor. Troll-caught Coho salmon are from fisheries certified sustainable by the Marine Stewardship Council.
