文摘
- •
Lake Whitefish embryos incubated at 5 °C and 8 °C develop 1.5× and 3× faster than those incubated at 2 °C, respectively.
- •
Warmer incubation temperatures (5 °C, 8 °C) or acute heat shocks (+3 °C) do not affect survival of embryos.
- •
Constant colder (2 °C) incubation temperature produces larger embryos.
- •
Multiple, 1-h weekly heat shocks (+3 °C) over development do not affect time to hatch or pre-hatch embryo size.
- •
Lake Whitefish embryos unaffected by heat shock; persistent increased incubation temperature may have negative effects.
