Table 2: Mean (SE) spawning female sizes, reproductive data, and thiamine data from spawns of landlocked fall Chinook Salmon from Lake Oahe, South Dakota that either had some eggs survive to hatch or experienced complete mortality. Means with different letters across a row are significantly different (P < 0.05).
