Effects of environmental temperature on juvenile coho salmon ( Oncorhynchus kisutch ) experimentally infected with Vibrio anguillarum were examined at 7 water temperatures from 3 to 21°C. The mean day to death and total mortality were each related to temperature. The shorter mean day to death and higher mortality were observed at the elevated water temperatures. Growth curves of V. anguillarum cultured in Brain Heart Infusion broth were determined at 6, 12 and 18°C. Growth rates were directly related to temperature. The effect of temperature on the production of V. anguillarum agglutinating antibodies following parenteral injection was determined in juvenile coho salmon held at 6, 12 and 18°C. Titers were first observed on days 10, 15, and 25 in fish held at 18, 12 and 6°C, respectively.
