Abstract excerpt
The contractile properties and myofibrillar protein composition of fast muscle have been characterized in pure strains of two tropical fish Oreochromis niloticus and O. andersoni. Single fast muscle fibres were isolated from the abdominal myotomes and chemically skinned. The maximum tension-temperature relationships of fibres were similar at 25-30 degrees C, but diverged below 17 degrees C. At 10 degrees C,...
