Blood osmolality shift in juvenile red drum, Sciaenops ocellatus L. exposed to fresh water
Juvenile red drum, Sciaenops ocellatus , measuring 40–49 mm s.l. tolerated abrupt transfer from 28%osalinity sea water to fresh water (< l%o). A significant shift in blood osmolality from a level of about 350 mosmol l −1 in sea water to a new level of about 311 mosmol l −1 was experienced by fish...

| Summary: | Juvenile red drum, Sciaenops ocellatus , measuring 40–49 mm s.l. tolerated abrupt transfer from 28%osalinity sea water to fresh water (< l%o). A significant shift in blood osmolality from a level of about 350 mosmol l −1 in sea water to a new level of about 311 mosmol l −1 was experienced by fish after 48 h in fresh water. The shift was followed by a slight reduction in blood osmolality to a sustained level of 300 mosmol l −1 after 96 h exposure to fresh water. The overall effect of increased environmental calcium on blood osmotic pressure of young red drum was not significant at the level tested. |
