Population Origin and Water Temperature Affect Development Timing in Embryonic Sockeye Salmon

Predicting the future impact of changing thermal regimes on life history stages for wild fish requires a better understanding of the relative importance of population origin and offspring size on embryonic development. We assessed hatch timing and offspring size of Sockeye Salmon Oncorhynchus nerka in relation to egg size (variation from full‐sibling families), population origin, and temperature (three treatments of 10, 14, and 16°C). Both hatch...
