BOX 3-2000 JUNEAU, ALASKA 99802-2000 PHONE: (907) 465-4100 OFFICE OF THE COMMISSIONER December 13, 1988 Mr. Lance Trasky Chairman Bristol Bay Regional Planning Team 333 Raspberry Road Anchorage, AK 99518-1599 Dear Mr. Trasky: I was pleased to receive for review and approval the completed Bristol Bay Comprehensive Salmon Plan prepared by the Bristol Bay Regional Planning Team. The care and professionalism exercised in developing the plan is indicative of the effort made by the team to address the unique salmon production needs and environment in Bristol Bay. Because the sockeye salmon produced in the Bay area is so important not only to the Alaskan but also to the world economy, exercising meticulous and considerate approaches to the planning process was essential. I believe, given the constraints and importance of the salmon resource in Bristol Bay, that the plan emerges as a critical document for ensuring the long-term vitality of these fish stocks. Thank you and the other team members for your dedication to the planning process. Sincerely, (' .:/ , >L:i;1tt<d.,L&~<-- Don W.

The commis sioner shall designate regions of the state for the purpose of salmon production and have developed and amend as necessary a comprehensive salmon plan for each region, including provisions for both public and private nonprofit hatchery systems. Subject to plan approval by the commissioner, comprehensive salmon plans shall be developed by regional planning teams consisting of department personnel and representatives of the appropriate qualified regional associations formed under Section 380 of this chapter." ANILCA: Alaska National Interest Lands Conservation Act of 1980. AQUACULTURE: Culture or husbandry of salmon (or other aquatic fauna/flora) . CARRYING CAPACITY: The maximum number of salmon fry or juveniles (individual organisms) that a stream or ocean (closed system) can support. ELECTROPHORESIS: A biochemical technique useful in establishing genetic differences of fish. The technique is used to help separate different stocks of fish from a mixed stock. ENHANCEMENT: The application, to a stock already at natural capacity, of procedures designed to increase the numbers of harvestable fish to a level beyond that which could naturally be produced. This may be accomplished by using a~tificial or semi-artificial production systems or by increasing the natural productive habitat by physical or chemical modification. ESCAPEMENT: Unharvested fish returning to spawning area for reproductive purposes. EX-VESSEL VALUE: Value of the catch when delivered from the fishermen to the first buyer. FINGERLING: A young salmon that has doubled its weight at emergence from gravel but has not begun its seaward migration. FRY: A young salmon that has emerged from the gravel but has not yet doubled its emergence weight. HABITAT PROTECTION: Maintenance of current fishery spawning and rearing areas through use of environmentally sound measures. vi HARVEST MANAGEMENT: Assuring adequate escapement yet allowing for optimimum harvest levels. INCIDENTAL CATCH: Harvest of a salmon species other than the target species for which the fishery is managed. INSTREAM INCUBATOR: A device located adjacent to a stream that is used to contain, incubate, and hatch salmon
