✦ Synopsis

A method is presented for isolating cardiac mitochondria from bony-fish. Calcium levels in ventricular whole tissue and isolated mitochondria of Gadus virens L. are determined by atomic absorption flame spectroscopy, and were found to be about 8 and 16 nmolCa/mg prot., respectively. In conclusion, the calcium concentration within the myocardial mitochondria in this species may be nearly three times higher than at the outside, and probably these structures serve as a "calcium sink". The results are compared with those previously reported for mammals.
