The Contemporary Harvests and Use of Resident Fish Species in the Copper River Basin, East Central Alaska
This report documents Ahtna traditional knowledge of non-salmon species fish and provides quantitative data on the current harvest of non-salmon species by residents of the Copper River Basin. Up until the middle of the 20th century non-salmon fish species played an important role in the traditional economy of the Copper Basin. The Ahtna elders interviewed for this project have gained considerable knowledge about nonsalmon species and their comments reveal a keen understanding of ecosystem dynamics recognizing the connection between annual fish migrations, seasonal water fluctuations and hydrology. This information adds considerable insight to the general scientific knowledge of non-salmon species within the Copper...
In recent years the management of the Copper River has provided an abundance of salmon but there are indications that certain wild stocks of sockeye and Chinook salmon may have declined from historical levels. In particular local people have indicated that climate change, beaver dams, and human use have altered salmon runs on certain tributary streams of the Copper River. Collecting traditional knowledge about past and present runs and correlating that data from the natural and social sciences (e.g. biology, geography, geology, anthropology, and archaeology) would extend our temporal knowledge of the Copper River salmon fishery and supplement and validate indices of abundance for Chinook and sockeye salmon.

This research combines Ahtna environmental knowledge with data from the biological and social sciences to document changes in the upper Copper River salmon fishery. Information in this report covers the period from 1989 to 2004. Ahtna elders have observed that over time, fisheries management and competition from other users have adversely affected the productivity of subsistence harvests. The Ahtna attribute effects on salmon spawning in the headwaters of the Copper River to environmental pollution and interception by commercial and recreational fishers. Since 1889, when the commercial fishing industry began, historical reports document various effects on Copper River salmon stocks and subsistence harvests. The...
