Datasets:
EVOSTC Data Archive: This project estimated pink and chum salmon fry loss due to avian predation immediately following fry release at the Esther Island hatchery, April-June 1995. The data include counts of gulls (white birds) from aerial transects, counts of bird species from boat transects, and plunge-dive success rates of birds in mixed-species foraging flocks. The aerial surveys were flown over several hatcheries; boat transects and behavioral data are from birds in Lake and Quillian Bays, Esther Island. Spreadsheet, ASCII files and reports. Availability: Available to collaborating researchers and managers and through the scheduled release of the SEA database.
