Fish heart is called venous heart because it receives blood from the veins and transfers it directly in to the gill for oxygenation.
The oxygen plays an important role in the respiration process and goes a long way in transmission of the blood in one complete circuit.
Blood circulation is referred to as single circulation along with heart that is known as circular heart.

Venous heart means the right part of the heart consists of right atrium and right ventricle. The right atrium receives de-oxygenated blood from the body; the right ventricle pumps this blood to the lungs
