“…The scaling of aerobic and anaerobic energy metabolism during locomotor activity is perhaps best studied in fish where red (aerobic) and white (largely anaerobic) muscle tissue are well differentiated. This arrangement allows for more accurate measurement of the mass of each type of muscle, their metabolite production, and electromyographic activity (Wittenberger, Coprean & Morar, 1975 ;Johnston, 1977;Bone, Kiceniuk & Jones, 1978;Black & Love, 1986). These studies indicate, as suggested earlier, that anaerobic metabolism is only invoked when the energy demand cannot be supplied b!…”

“…(Wittenberger 1972), and (4) lactate recycling (Wittenberger et al 1975). Thus, the proposed metabolite role of fish red muscle as defined by these authors appears analogous to certain well-established physiological functions of the mammalian liver as reviewed by Schimassek et al (1973).…”

The activities of lactate dehydrogenase (LDH) (L-lactate: NAD+ oxidoreductase, EC 1.1.1.27) can be divided into a lactate oxidase (lactate to pyruvate) and pyruvate reductase (pyruvate to lactate) component. These activities were examined in red and white muscle excised from the American eel Anguilla rostrata as an estimate of tissue lactate utilization, and compared with the kidney, gill, heart, and liver patterns. Phosphoenol pyruvate carboxykinase (PEP CK) activities in red and white muscle and liver were estimated as a marker for tissue gluconeogenic potential. Consistent with the possibility of lactate utilization for gluconeogenesis, both red muscle and liver possessed an active PEP CK and a bifunctional LDH, where oxidase activities were of the same magnitude as reductase activities. Kidney, which in mammals possesses gluconeogenic capabilities, together with heart and gill, also demonstrated LDH profiles consistent with the liver and red muscle enzymes. White muscle LDH was found to be essentially a pyruvate reductase and no PEP CK activity could be detected. These results suggest that eel red muscle has the potential to utilize lactate and has at least some of the enzymes required for gluconeogenesis. Therefore, the capacity of red muscle to perform a metabolic recycling function in addition to contraction cannot be excluded.

“…This was considered to be either preparatory deposition of lipid as fuel for migration or indication of reduced contractile ability and an enhanced ancillary recycling role. Wittenberger (1 973) and Wittenberger et al (1975) have demonstrated a mechanism in Cyprinus carpiu whereby red muscle acted in a lactate-for-glucose exchange system with white muscle. Such a system operating in Anguillu would allow the sustained activity necessary for slow swimming to be performed by white muscle providing that the muscle was capable of graded response.…”

The structure and distribution of red and white muscles have been investigated in female Anguiffa anguilla of varying sexual maturity. Red muscle volumes increased with sexual maturation from approximately 5% of total muscle volume in sexually immature eels to a maximum of 13.3% in sexually maturing animals. Volume increase was due to increasing fibre diameter rather than recruitment of new fibres. Intracellular volume fractions of lipid and mitochondria increased markedly in maturing fish. Artificially matured eels showed the largest increases in muscle lipid. The possible functional roles of red and white muscle during migration are discussed.
