CO2-induced ocean acidification leads to neurological
disorders in fish with unknown consequences for marine
ecosystems. In order to investigate the exact mechanisms
of how CO2 interferes with the teleost nervous system we
developed a stereotactic holding device enabling
in
vivo
MR
imaging and spectroscopy on the brain of fish for
several days without use of anaesthetics during the
experimental procedure. This setup was used to acquire
anatomical images of the brain of an Antarctic
Notothenoid to identify possible regions for future
studies. Following we investigated the effects of severe
hypercapnia on the acid-base and energy status.
