A qualitative histochemical study has been made of the myotomal muscles of five teleost fish (glass fish, Chanda ranga; carp, Carassius carassius; coalfish, Gadus virens; black mollie, Molliensia sp. and grey mullet, Mugil cephalus ) . Three or four main fibre types were distinguished in these species on the basis of the distribution and relative activities of glycogen, lipid, aglycerophosphate dehydrogenase, phosphorylase, and succinic dehydrogenase. The so‐called red and white fibre types were found to have similar histochemical properties to previously investigated species. All the species studied, with the exception of the glass fish, Chanda ranga , were found to have one or two types of pink fibre situated between the red and white fibre regions. In the carp, coalfish and mullet, the pink fibres were found to be composed of small and large diameter fibres which were similar to red and white fibres respectively, except for their staining for succinic dehydrogenase. Considerable differences were found in the relative amounts of pink muscles between species. Minor fibre components were found in several species. These consisted of very small diameter fibres which did not stain well with any of the histochemical procedures used. It is suggested that these fibres represent areas of continuing muscle growth. The results obtained are discussed in relation to the division of labour between myotomal muscles during swimming.
