Fishing motion, that is, fishing rod, line, sinken and fish, are modeled by multi-body dynamics used links, strings and dampers. On the other hand, fishing motion is measured by taking a photograph with high speed camera and the joint motion and angle between links are digitized and represented by polynomial equation. More over the extension force of line when fish pull the line is measured. Then, fishing motion of a crucian fish is simulated. By using this simulation, fishing rod which a fish hung by hook does not easily release is investigated. Then it is known that the long rod is better than short rod. In the fishing, tip of a rod is usually in the water, then drag force of the rod in a water is large. So a rod which drag force is small is desired. It is known that to minimize the force, stiffness of tip of rod is smaller.
