Nissui

Working together with NEC Corporation, Nissan Group company Kurose Suisan Co. Ltd. has developed technology for monitoring yellowtail growth. An underwater camera takes pictures of fish in the cage. AI technology identifies the individual fish targeted for measurement and simultaneously measures various parts of the fish’s body. Coupled with extensive data collected by Nissui over the years, this technology makes it possible to calculate fish weight. In fish farming, it’s important to have information about the feed amount used and fish growth rate so as to feed the fish with the optimum amount of feed. Until now, growth had been managed by sampling fish one by one and measuring their length and weight. With AI and IoT, it’s now feasible to measure a greater number of fish much more quickly, with dramatically improved accuracy and no stress to the fish.
