Trout recover from heart attack damage Most fish's hearts have to scavenge whatever oxygen is left in the poorly oxygenated blood returning from the body, absorbing what remains of the life-giving gas through the spongy myocardium. But not super athletic salmonids. Their hearts benefit from a well-oxygenated blood supply to the outer layer of the ventricle, the chamber that pumps the blood through the gills and body. However, this arrangement leaves their hearts vulnerable if the blood supply
