| Zusammenfassung |
| Ocean acidification, as a consequence of increasing marine pCO2, 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 life-history stages are potentially more sensitive – particularly
the critical stage of fertilization, in which sperm motility plays a central
role. In this study, the effects of ocean acidification (decrease of
pHT to 7.55) on sperm motility of Baltic cod, Gadus morhua, were assessed. We found
no significant effect of decreased pH on sperm speed, rate of change of
direction or percent motility for the population of cod analyzed. We predict
that future ocean acidification will probably not pose a problem for sperm
behavior, and hence fertilization success, of Baltic cod. |
