| Abstract |
Early life history studies and development of culture methods of the mountain whitefish (Prosopium williamsoni) were conducted in the Logan River, and in the Utah State Research Laboratory and USU Fisheries Laboratory. Spawning was observed in the laboratory and the Logan River from mid-November to mid-December during dusk. At ambient river temperature from 1.7-6.1C eggs began hatching after 79 days and continued for 23 days. Total mortality to hatch of eggs from weekly collections from five areas was 92%. In the laboratory, at 7.2C eggs began hatching in 52 days and continued for 23 days; at 8.9C in 45 days and continued for 30 days. Larval whitefish from two areas showed differences in growth due to temperature experience. Growth was examined in the laboratory at 6, 9, and 12C. A simple linear model for predicting growth was developed. |
