Abstract
Histological examination of gills of rainbow trout, Salmo gairdneri Rich. reared in freshwater ponds, introduced into the Baltic Sea, and kept in flow-through fresh water tanks an d in tanks with the Baltic water showed marked changes to take place in the gill microstructure of those fishes kept in sea water. Increased numbers of chloride cells, decreased size of mucous cells as well as a reduction in laminated branchial epithelium adjacent to gill filament blood vessels have been observed.
