Maintain and expand shellfish enhancement on tribal tidelands. The Lummi Bay Shellfish Hatchery is responsible for propagating and restocking tribal tidelands with manila clam seed (20 million seed) and oyster spat (3,000 clutch bags) annually. The hatchery also produces and sells geoduck seed to offset operation costs. These enhancement activities should be continued to support tribal harvest and may be expanded in response to climate change. For example, seeding or transplanting oysters and clams into new areas that are more likely to be successful as sea levels rise (i.e., assisted migration) may maintain opportunities for tribal harvest. Other actions such as enhancing the substrate of shellfish beds may also help maintain tribal shellfish harvesting opportunities.
