Atlantic cod in for even more stress?

g back alive to Bremerhaven and can then study in the over 100 new basins of our aquarium facility", explains Felix Mark.

The planned experiments include performance analyses in the ultra-modern flow channel and the two MRI scanners of the Alfred Wegener Institute in Bremerhaven. "Using this apparatus we can not only look into the brain of the fish but even into its individual cells. We are able to recognise, for example, how its metabolism alters within the cells, how heart and blood circulation of the fish react to the rise in water temperature, at which pH value of the water the fish reaches its performance limits or in which way temperature and degree of acidification affect its senses", explains Felix Mark.

The researchers know from investigations of tropical fish, for example, that their offspring have a reduced sense of smell as ocean acidification rises. The consequence: the young fish find it more difficult to return home and are more likely to fall prey to others. So are heat-shy Atlantic cod and its Arctic cousin facing a similar fate in view of climate change? Flemming Dahlke's first results are at least interesting: "There are many signs that the water temperature plays an important role in the breeding of the cod. There was as virtually no life in those eggs fertilised in sea water at a temperature of twelve degrees", reports the phd student.
