## Abstract Branchial chloride cells (CC) were studied in sea bass (__Dicentrarchus labrax__) maintained in seawater (SW: 35β°) or gradually adapted to and subsequently maintained in fresh water (0.2β°) or doubly concentrated seawater (DSW: 70β°). Changes were observed in the location, number, and str

β¦ Synopsis
The occurrence of granular epithelioid cells in the kidney arterial vessels was studied in one-and two-year-old Atlantic salmon during the physiological fresh-and seawater periods. The purpose of this study was to make long-term comparison on the morphology of the renin angiotensin system in the same fish species. One-year-old salmon living in freshwater had a statistically significant higher number of granular epithelioid cells (39.9 f 8.3/mm arterial vessel) than the

## Abstract Changes were measured in the numbers of chloride cells and the levels of (Na^+^ + K^+^)βdependent ATPase in the gills of immature, yellow eels and mature, silver eels during adaptation from freshwater to seawater. The percentage of chloride cells in yellow eels more than doubled after s
Juvenile Atlantic salmon __Salmo salar__ were shown experimentally to make adaptive behavioural decisions as a shortβterm response to changes in food availability and predation risk. Restricted food availability caused an increase in activity, whereas activity was decreased under predation threat. A
