Do sculpin exhibit torpor to offset low food periods?

Do sculpin (Cottus sp.) exhibit torpor to offset low food periods?

Many organisms struggle during periods of low food availability. In order to survive they down regulate their metabolic rate and go into a hibernation state. However, for non-mammals this state is referred to as torpor. The objective of this project is to conduct record of the metabolic rate of sculpin (Cottus sp.) experiencing torpor within a lab setting. This project is important as little work has been done in this field and may provide clues into over winter survival, compensatory growth, and pulsed feeding regimes.
