Tuna, which are sensitive to environmental changes, lose and increase their appetite depending on the weather and water temperature.
Providing too much feed can kill the fish because it can deteriorate the water quality, according to Sojitz.
The Tokyo-based company plans to have AI calculate the optimum amount of feed to nurture the fish after analyzing data on how the weather and water temperature affect their appetite based on technology developed by NTT Docomo Inc. and others.
A bluefin tuna farm in Matsuura, Nagasaki Prefecture, operated by Sojitz Tuna Farm Takashima Corp., a wholly owned subsidiary of Sojitz, is the site for the experiment.
At the farm, a team controls all study data, including water quality in the ponds and the amount of feed the tuna consumed.
The study is expected to continue for four to six months.
