Why can the eel, unlike the trout, migrate under pressure.

Abstract

In order to elucidate the difference between pressure resistance in trout (Onchorhyncus mykiss) and eel (Anguilla anguilla), oxygen consumption of red muscle permeabilised cells and mitochondria were measured at 101 ATA hydrostatic pressure per se. Such an experiment involved the setting up of a special system allowing measurements under high pressure. The results show that hydrostatic pressure strongly alters the oxidative phosphorylation in trout but not in eel, which exhibits mitochondrial pressure resistance. It is hypothesised that the eel has a supranormal mitochondria functioning at atmospheric pressure in order to cope with the high pressure environment encountered during its migration.
