Fig. 1. (A) Temperature profiles. Water temperature was decreased by cooling,
beginning on 15 January 2004, and fish were either starved (filled circles) or
fed (open circles). Control fish (squares) were maintained under ambient water
temperature conditions (2004) and fed. Filled inverted triangles indicate
sampling dates. (B) Cumulative mortalities for fed and starved rainbow smelt
Osmerus mordax subjected to a controlled decrease in water
temperature. The date at which the temperature decrease was initiated (i.e. 15
January 2004) is used as day 0. Initial population size was 130 for both
groups.
