Survey and Evaluation of Instream Habitat and Stock Restoration Techniques forWild Pink and Chum Salmon. Restoration Study Number 105-1 (Restoration Project 93063). EXXON VALDEZ Oil Spill State/Federal Natural Resource Damage Assessment Final Report

摘要

This project is the result of a three-year survey of the Exxon Valdez oil spillimpact area to identify appropriate and cost-effective instream habitat restoration techniques for salmon, including spawning channels and improvement of fish passage through fish ladders or step-pool structures to overcome physical or hydrological barriers. Additional wild salmon stock rehabilitation measures include stream-side incubation boxes, remote egg-taking, incubation at existing hatcheries for fry stocking in oil-impacted streams, and fry rearing. Study results include the identification of the most promising instream habitat restoration projects in each of the spill-impacted areas.
