The 34% increase in relative ventricular mass ( M rv ) resulting from chronic anaemia (induced by an intraperitoneal injection of phenylhydrazine hydrochloride) was accompanied by a 117% increase in coronary vascular volume of diploid rainbow trout Oncorhynchus mykiss . Coronary vascular volume of normocythemic triploid fish was similar to that of normocythemic diploid fish despite a larger M rv . These observations, in combination with previous studies, suggest that the vascularity of compact myocardium in O. mykiss can vary independently of M rv .
