... characteristics examined under different acclimation conditions. Significantly lower plasma Cl − was detected in fish from coastal rivers than in fish from the other two habitat types during the IPW treatment, which was also significantly lower compared with that in ALW. Similarly, gill Na + /K + -ATPase activity...

...) in all 18 possible combinations for 6 days using separate trials for three smolt statuses (pre-smolt, smolt and de-smolt). In addition, changes in juvenile behaviour, plasma variables, gill Na + /K + -ATPase activity, body size, body morphology and skin pigmentation supplemented the gene expression...

... the functional capacity of the SI. We examined changes in the function( l -proline uptake rate and capacity) and metabolism of the SI( in vitro oxygen consumption, Na + /K + -ATPase activity and abundance) of C. alboguttata following 6 months of aestivation. l -Proline uptake rate was significantly higher...

... positive, mean +1.9±0.2 mV) were all positively correlated with TER. In contrast, preparations cultured using an earlier single-seeded insert (SSI) technique contained only pavement cells and exhibited a negligible TEP under symmetrical conditions. Na + /K + -ATPase activities of DSI preparations were...

... of juvenile rainbow trout ( Oncorhynchus mykiss ). Gill CR concentration ( B max ) and affinity ( K d ) were assessed using a radioligand binding assay with the synthetic glucocorticoid triamcinolone acetonide. Gill responsiveness to cortisol was quantified by measuring in vitro Na + /K + -ATPase activity...
