We assessed the turbidity measurements of ovarian fluid and ovarian fluid mixed with lake water, distilled water, and well water for their potential to predict egg survival of landlocked fall Chinook Salmon Oncorhynchus tshawytscha from Lake Oahe, South Dakota. Turbidity of the ovarian fluid alone ranged from 23.1 to 101.7 NTU, and mean turbidity increased with the addition of any of the water sources. Egg survival to the eyed stage ranged from 0% to 61%, and was not significantly correlated with ovarian fluid turbidity or the turbidities of any of the ovarian fluid and water combinations.
