Seafood processing industry
Most of the employment in the community was from the local seafood processing plant, which operated in the summer months. There was briefly a fish sauce plant that used the byproduct of the main processing plant. Removal of the fish sauce plant and its contents and clean-up of the site begin in July 2026. The fish plant was destroyed by fire in November 2025 and as of August 2026 had not been rebuilt. At the time of the fire, the St. Mary's Bay Fisheries plant, owned by Daley Seafoods Inc, employed up to 300 workers.
