"The report herein on Restoration Project 96258A-1 describes the final research findings on the production of sockeye salmon from the Kenai River system impacted by the 1989 Exxon Valdez oil spill."--Page ii.

Genetic data from sockeye salmon were collected from the Kenai River and from all other significant spawning populations of mixed-stock harvests in Cook Inlet, Alaska. Allozyme data reveal substantial genetic diversity among populations. Samples from fish wheels in the Kenai, Kasilof, Yentna, and Susitna rivers were also analyzed.

This report is the fourth in a series of ongoing investigations of large sockeye salmon escapements in the Kenai River system and in Rad and Akalura lakes on Kodiak Island. The overescapement event resulted from over abundance of juvenile salmon rearing in lakes caused by presence of Exxon Valdez oil on the fishing grounds in Cook Inlet and the Kodiak area in 1989.

"Simulates sockeye salmon production using a spawner-recruit relationship, modifies the simulated production for year of return using an age-structure sub-model, estimates annual returns by summing across age groups, and estimates resulting catches and escapements under user-specified harvest strategies"--Leaf 1.

This report only details the collection phase of the genetic stock program. The objectives of the program is to "(1) improve stock identification capabilities by combining parasite and genetic stock identification information data in algorithms to provide estimates of Kenai River stocks in the mixed stock fishery of Upper Cook Inlet (UCI); (2) provide more accurate estimates of abundance of Kenai River sockeye salmon with UCI by increasing sampling power of the offshore test fishing program"--P. 1.

"The primary purpose ... was to assess whether the Bendix side scan sonar counter counting threshold was set low enough to enumerate all salmon species"--P. 1.
