Effect of ocean acidification on marine fish sperm (Baltic cod: Gadus morhua)
Ocean acidification, as a consequence of increasing marine p CO 2 , may have severe effects on the physiology of marine organisms. However, experimental studies remain scarce, in particular concerning fish. While adults will most likely remain relatively unaffected by changes in seawater pH, early l...
