Fishery Management Report for the Recreational Fisheries of the Upper Copper/Upper Susitna River Management Area, 2010.

摘要

Sport, personal use, and subsistence fisheries season summaries for 2010 and preliminary information for 2011 in the Upper Copper/Upper Susitna Management Area (UCUSMA) are presented. The UCUSMA consists of all waters and drainages of the Copper River, upstream of Haley Creek and all waters and drainages of the Susitna River, upstream of the Oshetna River. The areas king, sockeye, and coho salmon are targeted in sport, personal use, and subsistence fisheries. Other resident and anadromous fishes such as burbot, lake trout, rainbow/steelhead trout, Arctic grayling, and Dolly Varden are targeted in year-round sport fisheries. Whitefish are mainly targeted in subsistence fisheries. Sport angler effort was 40,912 angler-days in 2010. Total sport catch in 2010 was 116,106 fish, with Arctic grayling making up 54,882 fish of this total. Sport harvest totaled 29,398 fish in 2010, with sockeye salmon accounting for 50% of the harvest. In the Glennallen Subdistrict state subsistence fishery a total of 73,260 salmon were harvested in 2010 which is the highest harvest since 2001. Sockeye salmon represented over 96% of the subsistence harvest. The Chitina Subdistrict personal use fishery state harvest totaled 141,565 salmon in 2010. Overall, the UCUSMA fish stocks are healthy and harvests appear sustainable, but significant challenges exist to maintain sustainable stocks in the face of decreasing returns or increased effort on specific lakes and flowing waters.
