In order to increase fishing efficiencies of the fyke net used in the coast of Cheju Island water tank experiment was caried out entering and escaping behavior using nets that were reduced to 1/20 of the size of fyke net and were improved to have antrance structure, and Mackerel Scomber japonicus as experimental fish. The results of measurement are as follows: 1. Fish school behavior in the main net was showed two different patterns: swimming in a circle in the right space of the main net and swimming back and forth in ellipse in the right and left space. 2. The swimming speed of mackerel school was 24.9. 12.6 and 32.0cm/sec in the center space. right space of main net and in the mouth. 3. The entering rate of fish school was 40% in net with 35cm length of the upper and funnel net in the mouth of fyke model net and 49% in conventional type fyke model net. 4. The escaping rate of fish school was 10% in net with 35cm length of the upper and funnel net in the mouth of fyke model net and 69% in conventional type fyke model net. 5. The remain rate of fish school was 90% in net with 35cm length of the upper and funnel net in the mouth of fyke model net and 31% in conventional type fyke model net.
