Abstract
Daily 2- to 3-h treatments with seawater safely and effectively controlled Saprolegnia diclina on eggs of pink salmon (Oncorhynchus gorbuscha) in two trials at Auke Creek Hatchery, southeastern Alaska. Survival in gravel incubators from the fertilized-egg stage to the fry stage was significantly higher (P<0.005) with seawater treatment (68%) than with no treatment (41%). In tray incubators, survival from the fertilized-egg stage to the eyed-egg stage averaged 95% for the 1971 to 1976 broods after malachite green treatments and 96% for the 1977 brood after seawater treatments.Keywords
