Synopsis
Contraction time of an isolated white muscle from the temperate water Girella tricuspidata is proportional to temperature and inversely proportional to fish size. Between ambient (14°C) and 8° C muscle from all sizes of fish is similary affected by temperature; the lower the temperature the more the contraction time is slowed. Below 8° C muscle from large fish is affected more than is muscle from small fish. Contraction time of white muscle in the antarctic notothenioid Pagothenia borchgrevinki is about twice as fast as that of Girella tricuspidata at temperatures between 2–12°C, but at normal body temperature, contraction time of muscle from Girella tricuspidata (14°C) is about twice as fast as that of Pagothenia borchgrevinki (−1.9°C).
