The research objects are counted by the number of heartbeats different current treatments. The purpose of this study was to determine the heart rate of tilapia (Oreochromis niloticus), a basic knowledge of predicting the rate of metabolism and respiration and heart rate also determine the activity of tilapia at different swimming speeds, in the process of catching up with the use of active fishing gear. The higher the flow rate used in tilapia fishes the heart rate up, and seen in the relative heart rate ranging from (1.1 to 3.78), a portrait that fish require a lot of energy so that the fish is also increasing the body's metabolisme.otherHeartbeatsTilapia (Oreochromis niloticus),FlowSize Fishstudent Paper Post Degree
