- Shapes of Entrance in Basket Traps and Fishing Mechanisms

抄録
Various shapes of entrance in basket traps were used in rivers of southern Kyushu and their fishing mechanisms were studied. Dimensions of basket traps were measured and their physical characteristics were examined. The external shapes of entrance were divided into two categories by current conditions at the area where basket traps were used. The basket traps in deep rivers have a square shape with a short, large angled throat. Two types of basket traps were used in shallow rivers ; one has a cylinder shape with a long, small angle throat, and the other has no throat. The angle of entrance without throat was inclined. The curved shape of entrance seemed to guide fishes into the basket trap and to hold them inside. The inclined angle of entrance for shrimp was smaller than that for fish. It may be assumed that the shapes and angles of entrance in basket traps could be affected by current conditions in and around the traps as well as by swimming behaviours of the target fish.
