Software development using smartphone-based data input for determining the energy-saving effect of fishing boat deceleration

  • Easy-to-understand materials and pamphlet that will educate fishermen on how to save energy using their fishing boats.
  • A free software, “Dr. Sho-ene,” has been developed that allows fishermen to estimate the amount of fuel savings by decelerating their fishing boat from the data inputted using portable terminals such as smartphones.

Fishing management has been economically difficult due to the recent increase in fuel costs. To reduce further expenses on fuels, conventional fishery operations have to be converted into energy-saving fishery activities.

The National Research Institute of Fisheries Engineering (NRIFE) and the Marine Fisheries Research and Development Center (JAMARC) of the Fisheries Research Agency (FRA) have conducted a research on promoting energy-saving measures in fisheries using fishing boats. As a part of the results of this research, the NRIFE and the JAMARC developed a guidebook for energy saving in fisheries using fishing boats, which includes energy-saving measures and theories, as well as a pamphlet for fishing boat operators that summarizes the lessons presented in the guidebook.

The NRIFE and the JAMARC have also produced “Dr. Sho-ene” software that allows fishermen to estimate the amount of fuel savings by decelerating their fishing boats, accessing the website, and inputting the length, width, and horsepower of their fishing boats using portable terminals such as smartphones. This software then calculates the amount of energy savings resulting from the deceleration of the fishing boat.

These materials and software are free and available at the following URL:
The use of these materials and software will serve as a medium for disseminating the use of energy-saving measures in fisheries and in the conversion of traditional fishing methods into energy-saving fishing activities.

Note: This is applicable to fishing boats with inboard motors such as trawlers and not small-sized fishing boats with outboard motors.
