Electrolyte changes and volume regulatory processes in the carp (Cyprinus carpio) during osmotic stress

Effects of Dietary Inosine 5′-Monophosphate Supplementation on the Growth Performance and Salinity and Oxidative Stress Resistance of Gibel Carp (Carassius auratus gibelio)

“…Normally, freshwater teleost fishes obtain water through osmosis and tend to actively take up salt across their gills, possibly leading to the ingestion of iron from food and the excretion of relatively diluted urine [43]. After transfer from freshwater to saltwater, the K + and Cl − concentrations in the plasma increased and followed the course of osmolality, which was similar to the findings of a previous study [44]. We found that acute salinity stress increased the plasma cortisol concentration and the expression of Hsp70 and GR.…”

Estimating some physiological parameters in the blood of Tilapia zillii fingerlings during adaptation to different salinities

“…Walker et al (1989) found that haematocrit (Hct) was significantly lower (P ≤ 0.005) in saline-acclimated Catostomus commersoni than in the control animals. The same results for PCV values were noted in many studies on the grass carp (Maceina et al 1980), spotted gar (Smatresk andCameron, 1982) and carp (Hegab & Hanke, 1982). Indeed, the decreases in haematocrit and plasma protein and hemoglobin concentrations in the study of Wilkes and McMahon (1985) after 24 hrs transporting the freshwater fish Catostomus commersoni to hyper saline medium [0.94% sodium chloride /300 mosmol/L] suggest that the plasma volume was expanded during saline acclimation.…”

Effect of Different Salinity Levels on Growth Performance, Hematological Parameters and Proximate Composition of Cyprinus Carpio

“…The high level of salinity increases metabolic rate because of new osmotic conditions leads to control necessary ions through osmoregulation and to maintain the internal stability (homeostasis) which needs high energy cause reduction in growth rate and effects the feed conversion ratio and feed intake. Abo-Hegab & Hanke, (1982) describe changes in feed conversion rate of common carp with the increase of salinity upto15-ppt. DeBoeck et al (2000) studied common carp (Cyprinus carpio) at 10-ppt salinity and found negatively impact on feed conversion rate, weight gain and feed intake while Laiz-Carrión et al (2005) describes the effect of salinity on fish reported poor growth performance depends on species and duration of exposure.…”
