Description

<p>In this paper, the authors report the Internet of Things （IoT） and its applications for the set-net fishery. The sustainable fisheries will be realized through compatibility between the sustainability of fishery resources and the sustainability of fishery management. However the total catch has been decreasing year by year, so improvement of productivity is an urgent issue. Therefore, the authors developed the cloud type echo sounder and installed it to a set-net. It is possible to visualize the inside of the set-net by creating the acoustic images from the acoustic data. In the fishing season of 2015, the fisherman learned the features of each fish by looking at the images after operation. While in the fishing season of 2016, fisherman made an operation plan by looking at the acoustic images before operation. As a result, on the other hand consumption of fuel in 2016 decreased by 3.2% compared to 2015, the total catch increased by 32.3%. Therefore, IoT contributed to improvement of productivity and reduction of CO2 emissions. Nowadays, the authors have been working on the creating big data of set-net fishery. In the near future, artificial intelligence will predict the catch of tomorrow and the set-net fishery can be sustained.</p>
