Feeding and swimming can influence ion balance in fish. Therefore we investigated their
impact on ionoregulation and its hormonal control in goldfish and common carp. As …

This study aims to examine ionoregulatory parameters during exercise and cortisol elevation
in common carp fed different food rations. Fish subjected to two different feeding regimes …

In the present study, the combined effects of hypoxia and nutritional status were examined in
common carp (Cyprinus carpio), a relatively hypoxia tolerant cyprinid. Fish were either fed or …

The hydromineral and metabolic actions of thyroid hormone on osmotic acclimation in fish is
less understood. We, therefore, studied the short-term action of triiodothyronine (T3), the …

Exposure of adult crayfish Pacifastacus leniusculus to Artificial Freshwater (AFW) media
containing 1.5 m and 0.15 mmol. l–1 total ammonia [T amm; 0.1× acute lethal concentration …

The interactive effects of ambient acidity and salinity on thyroid function are less understood
in fish particularly in air-breathing fish. We, therefore, examined the thyroid function …

Fishes have developed many complex physiological mechanisms to combat osmotic
challenges. In this study triiodothyronine (T3), thyroxine (T4) and cortisol in the plasma were …

The evolutionary transition from water-breathing to air-breathing involved not only a change
in function of the organs of respiratory gas exchange and N-waste excretion, but also in the …

The importance of salt and water absorption from the food by the gastrointestinal tract and its
impact on iono-and osmoregulation have been largely overlooked by fish physiologists. The …

The effect in freshwater rainbow trout of digesting a commercial pellet meal on the renal
handling of water, ions and acid–base equivalents was investigated through urine collection …
