Changes of blood chloride and osmolarity in two stocks of salmon parr ( Salmo salar ) during short-term exposure to seawater
Two stocks of hatchery-reared Salmo salar parr were tested for change of blood chloride and plasma osmotic concentration following their transfer from freshwater to diluted seawater for periods up to 256 h. One group of fish originated from an anadromous population (Atlantic salmon) while the others...

| Summary: | Two stocks of hatchery-reared Salmo salar parr were tested for change of blood chloride and plasma osmotic concentration following their transfer from freshwater to diluted seawater for periods up to 256 h. One group of fish originated from an anadromous population (Atlantic salmon) while the others were from a freshwater stock (ouananiche). The results suggest that, at least at the parr stage, the young salmon of both groups have very similar osmoregulation. |
