At the Nagasaki and Amami Oshima research sites, Maruha Nichiro is conducting basic development research on fully farmed bluefin tuna using the only terrestrial bluefin tuna parental fish tank in Japan and a vast outdoor farming facility. In particular, they are leading research in the field of bluefin tuna farming in Japan, such as the development of technology for egg collection by controlling the artificial environment and elucidating the information of the whole genome.

Maruha Nichiro was the first private company to be successful in producing fully farmed bluefin tuna in 2010 and began large-scale commercial shipments in 2015. In addition, with the aim of improving the productivity of bluefin tuna, including horse mackerel and amberjack , in aquaculture, Maruha Nichiro established the Aquaculture Technology Development Center Co., Ltd. in 2020, and they are working to breed farmed fish and improve roe production technology.
