Effects of high-pressure acclimatization on silver eel (Anguilla anguilla, L.) slow muscle contraction.
International audience As the spawning migration of the eel is supposed to correspond to a long swimming activity at depth, patterns of slow red muscle contraction have been investigated in European silver eel (Anguilla anguilla L.) exposed for 3 weeks to 10.1 MPa hydrostatic pressure. The results s...
