漁業者が活用しているマナマコ資源管理支援システムとその展開

抄録

The sea cucumber, Apostichopus armata （Selenka, 1867）, is an important biological marine resource in Hokkaido. We developed a sea cucumber resource management support system using information and communication technology to promote sustainable use of this resource. Fishing information is entered into the system by fishermen using an iPad, and positional information of the ship is recorded by a global positioning system logger and sent to a server, where it is stored. The data output from the server, such as quantity of the resource, natural increase in populations, and catch, can then be viewed by the fishermen throughout the fishing season. The fishermen are thus able to examine the data and adjust the length of the fishing season in order to prevent overfishing. The Rumoi Chiku Namako Bukai of the Shinsei Marine Fishery Cooperative achieved a V-shaped recovery in sea cucumber numbers after the introduction of the support system. In addition, we used the technology developed for the sea cucumber support system to develop a support system for bottom trawling.
