Fig. 4. Bar graph summarizing values of peak stress and oscillatory power output from muscles tested in vitro. Shaded bars, red muscle; white bars, white muscle. (A) Values for peak stress (force/cross-sectional area) in kNm^-2 for a variety of fish that cover a range of temperatures. (B) Power output in W kg^-1 fish. Data are reported only for muscles tested at temperatures that were the same as the acclimation temperature of the intact fish and are given in parentheses next to the fish name. In those cases where more than one study reported values, the range of values is indicated with error bars. For comparison, a value for frog sartorius is provided. Fish species for which data were reported include Hawaiian seargent (Abudefduf abdominalis), saddle wrasse (Thalassoma duperrey), shorthorned sculpin (Myxocephalus scorpius), trout (Oncorhyncus mykiss), scup (Stenotomus chrysops), largemouth bass (Micropterus salmoides), yellowfin tuna (Thunnus albacares), bonito (Sarda chiliensis) and saithe (Pollachius virens). ¹Johnson and Johnston, (1991b); ²Beddow and Johnston (1995); ³Johnson and Johnston, (1991a); ⁴Langfeld et al.
