| Summary: | body curvature. Many species, including cod (Gadus morhua) and Johnston (1990) found that the time needed to activate or velocity (V0) decreased with increasing body size, scaling as were present in fish less than 20 cm in total length with relative molecular masses of 17 (TnIf3), 22 (TnIf2) and 23and trout (Salmo trutta), use a subcarangiform swimming style in which the head is held rather rigid and the wavelength of body curvature increases towards the tail. Muscle contractile properties have been shown to vary from anterior to posterior myotomes in species using continuous subcarangiform or carangiform swimming styles. For example, in cod (Davies et al. 1995), saithe (Pollachius virens; Altringham et al. 1993) and scup (Stenotomus chrysops; Rome et al. 1993), times for isometric muscle twitches increased from anterior to posterior myotomes. In contrast, in the short-horn sculpin (Myoxocephalus scorpius), a specialist ambush predator, twitch and tetanus activation and relaxation times were not |
