“…The most pronounced seasonal changes were observed with the red musculature near the lateral line. Similar conclusion was reached also by Wittenberger and Diaciuc (1965) and Pora et al (1971) who found great differences in metabolic rate of the white and red muscle tissue, and similar metabolic rate in the red muscles and liver of the fish. In the present study, made in various vegetation periods and under different rearing conditions, moderate to very close correlation between the glycogen content in the organs under study and water temperature and daylight length was observed.…”

Svobodova Z.: Seasonal Changes of Glycogen Content in the Hepatopancreas and Musculature of the Carp (Cyprinus carpio L.). Acta vet. Bmo, 47, 1978: 39-50. The seasonal changes in the mass of hepatopancreas, its absolute and relative amount of glycogen, and hepatopancreas glycogen content per 1 g body mass were investigated in 1211 carP aged 4 months (Kr-1) to two years (KI ). Mter a sharp increase of these parameters during September and October, the highest glycogen amounts were found in November and December (28. 1 ± 1.23 g; 5.58 ± 0.369 g; 19.6 ± ± 0.2 % and 13.5 ± 0.76 mg, respectively). After a considerable drop in April and May, the lowest amounts of glycogen were noted in June and July (4.30 ± ± 0.200 g; 0.19 ± 0.018 g; 4.24 ± 0.326 % and 0.96 ± 0.117 mg, respectively).The parameters under study were closely correlated with water temperature and daylight length.Glycogen content of the white skeletal musculature, measured in 456 C8rP, oscillated from 0.34 ± 0.008 % to 0.81 ± 0.041 % and was found to be rather independent on the water temperature but highly dependent upon the daylight length. Glycogen content in the red musculature near the lateral line tin 300 carP) oscillated from 1.04 ± 0.063 % to 2.71 ± 0.083 % and was found to be highly dependent upon the daylight length. Glycogen content in the heart muscle of 300 carP oscillated from1.46 ± 0.077 % to 2.56 ± 0.049 %, and showed a close correlation to water temperature but only a mild one to daylight length. Circannual variations, water temperature, daylight length, carp.Intensification of fish farming brings about new problems resulting from occurrence of dift'erent predisposition factors. Health control in fish farms thus becomes increasingly important. It consists of external indicators such as the volume value and Fulton's conditional index (Krupauer and Hamai!kova 1973), and internal indicators such as the dry matter and fat content of the fish body (Vavruika and Janei!ek senior 1973). Up to now, little attention has been paid to the fish body glycogen content which is the immediate and readily available source of energy for biological processes, and, in addition, the main source of energy in the hypoxic environment; and the only source of energy in the anoxic water environment of the fish. The aim of the present study was, therefore, to investigate the complex of changes which may occur in the C8rP farming and are likely to inftuence the body glycogen stores of the fish (Svobodova 1976). Patterns of seasonal changes in glycogen content of the hepatopancreas, white and the red skeletal musculature and in the h~ musculature of the C8rP are presented in this paper. Materials and MethodsIn the years 1968-1970, the seasonal cycle of changes in the hepatopancreas mass and its glycogen content was investigated in monthly intervals in C8rP aged 4 months to 2 years (Kr_l and KJ from the experimental ponds No. 70 and No. 64. The fish were reared under semi-operational

“…It has been suggested that lactate produced in the white muscle is transferred to more aerobic tissue such as red fibres, gills, liver, and kidneys for subsequent oxidation to pyruvate. Our observations would thus serve as new arguments in favour of the hypothesis expressed by many authors (Braekkan, 1956;Wittenberger & Diaciuc, 1965;Wittenberger, 1967;Bilinski & Jonas, 1972;Driedzic & Hochachka, 1976;Bone, 1978;Hulbert & Moon, 1978).…”

The ultrastructure of myotomal muscles of the golomianka, Cormephorus baikalensis Pallas

An ultrastructural study of the myotomal muscles in the golomianka, Comephorus baikalensis Pallas, revealed two main and distinct muscle regions: superficial and white. They were distinguished on the basis of histological and ultrastructural organization. Only the superficial fibre region shows homogeneous organization. The principal new finding is the unique ultrastructural organization of the superficial muscle fibres. Their myofibrils occur in the form of ribbons surrounded by large mitochondria.

“…The second hypothesis which has been advanced to explain the low accumulation of lactate in carp white muscle during hypoxia and exercise involves the noncirculatory transfer of metabolites between red and white muscles (Wittenberger & Deaciuc, 1965;Wittenberger, 1972;Wittenberger, 1973;Wittenberger, Coprean & Morar 1975). Principally this involves a transfer of lactate from the white to red muscle and of glucose from red to white muscle.…”

A comparative study of glycolysis in red and white muscles of the trout (Salmo gairdneri) and mirror carp (Cyprinus carpio)

The activities of some glycolytic and associated enzymes have been determined in the muscles of trout and carp to investigate the possibility that the discrepancies previously reported between lactate accumulation and anoxic tolerance in these two fish result from underlying differences in glycolytic potential. Steady state concentrations of certain glycolytic intermediates were also determined in freeze-clamped muscles from tankrested fish. The activities of hexokinase, phosphorylase and phosphofructokinase were approximately 2-3 times lower in carp than trout white muscles. Pyruvate kinase and lactate dehydrogenase activities were 5 times lower in carp white muscle. The lower, broader pH optima of lactate dehydrogenase and pyruvate kinase from carp compared to trout muscles is thought to be correlated with the greater anoxic tolerance of the carp. Glycolytic enzyme profiles were markedly different between the red and urhite muscles of the rainbow trout but broadly similar, with the exception of hexokinase activity, for the corresponding muscles of the carp. The results are discussed in relation to what is known about anaerobiosis in these two species and the comparative physiology of red and white muscles in fish.
