This report describes the mechanics of automatic circulating angling machines for skipjack devised by the authors and a result of angling tests. These devices can economize the angling space, that is the fish caught are gathered at one space so that the process from angling to storage is systematized. The authers would like to report the result of series of the experiments. 1) Two kinds of angling machines were made for experiments, one of which is the vertical circulating machine (S.V.M) and the other is the horizontal circulating machine (S.H.M). 2) Angling tests with both machines were carried out during the period from 1965 to 1975 in the southern area of the Pacific Ocean. There was no difference in angling ability between the two machines and well-trained fishermen under the same catching conditions. 3) The S.H.M proved to be more efficient than the S.V.M in performance other than angling. 4) It is ncessary to improve the S.H.M to prevent unhooking, before it is used practically. Also the bulwark of the vessel should be remodeled to fit the S.H.M.
