Effort, catch, and harvest of chinook salmon in the spring marine boat sport fishery near Haines, Alaska, 1993

Description

The Haines marine boat sport fishery targets wild mature chinook salmon Oncorhynchus tshawytscha returning to the Chilkat River. This fishery was closed during the spring of 1991 and 1992 because of conservation concerns for this stock. A limited fishery was allowed in 1993 with a maximum allowable harvest of 500 wild mature chinook salmon. Stratified two-stage direct expansion surveys were used to estimate angler effort for, and harvest of, wild mature chinook salmon in the Haines marine boat fishery during 1993. Harvest of large (>28 inches total length) chinook salmon and chartered angler effort and harvest were also estimated. Contributions of hatchery chinook salmon to the fishery were estimated from coded wire tag recovery information. Age and size compositions were estimated by using scale samples and lengths collected from chinook salmon in the angler harvest. An estimated 11,919 angler-hours (SE = 1,559) of effort (9,069 targeted salmon hours, SE = 1,479) were expended for a harvest of 314 (SE = 55) large chinook salmon, of which 252 (SE = 46) were wild mature fish. Chartered anglers accounted for 18% and 30% of the estimated targeted salmon effort and harvest of large chinook salmon, respectively. Hatcheries produced about 12% of the estimated chinook salmon harvest. Most of the hatchery fish harvested in this fishery were produced at the Hidden Falls hatchery and were released in 1990 at Lutak Inlet, north of Haines.
