The exploration and exploitation of ocean resources require appropriate marine equipment. Traditional propelled vehicles like HOVs, ROVs, and AUVs are less efficient compared to the swimming performance of fish. However, calculating the swimming efficiency of fish remains a challenge. Existing definitions and calculation methods have limitations, mainly due to a mechanical view of life that neglects the free-will of fish. To overcome these limitations, a new approach using task efficiency is proposed, which considers the influence of active force which is produced by mind-body interaction of a living fish. This new definition and calculation method offer several advantages over previous approaches and can be applied to increase task efficiency in designing and operating submersibles. In many cases, swimming efficiency is not the primary concern for submersible designers.
