Mark rates of fish collected from 3 tributary rivers (Chandalar River, Sheenjek River, and Fishing Branch River) and from the Yukon River near the international border were compared with the mark rate observed at the mark-recapture site on the Yukon main stem downriver near Rampart, Alaska. The hypothesis that mark rates in the gill net and fish wheel catches were equal was tested. A delayed and progressive mortality remains the single potential cause for declining mark rates upriver.

"Project objectives are to: 1. Test the hypothesis that the age and sex composition of rainbow smelt in Togiak River are similar during the winter subsistence fishery and spring spawning season; 2. Test the hypothesis that the mean lengths of rainbow smelt in Togiak River are similar during the winter subsistence fishery and spring spawning season; 3. Identify spawning locations and timing of rainbow smelt in the lower Togiak River; and 4. Estimate biomass of the spawning run"--Leaf 2.
