Abstract
    Stenohaline common carp (Cyprinus carpio) were chronically exposed to the two main osmoregulatory ions, Na+ and Cl, at levels close to their isoosmotic value for 28 d (171 mM NaCl; 324 mosm kg−1; 10‰). The aim of this study was to assess whether or not the disturbed ion and osmoregulation affected the energy demand and the energy stores of the exposed fish. Salt exposure reduced food intake by 70% and had adverse effects on growth and survival. Although food consumption decreased and growth was seriously affected, routine oxygen consumption of the exposed fish did not drop, indicating a reallocation of energy expenditure from growth toward other processes. A stress‐induced increase in plasma glucose was observed. As a result of low food intake, lower levels of protein were used for fuel. Protein use itself was probably replaced by the use of carbohydrates. These effects were confirmed by the depletion of both muscle and liver glycogen stores during the experimental period. We conclude that, besides the effects of reduced feeding, stress induced extra energy requirements leading to the depletion of energy stores.
