Sakana-kun Explores the Secrets Behind the Deliciousness of "Kurose Buri" in a New Video

Nippon Suisan Kaisha, Ltd. (Nissui) (President and Representative Director: Teru Tanaka, Minato-ku, Tokyo) has released a collaborative YouTube video with Sakana-kun titled "[Not Just for Winter] What is Kurose Buri That's Delicious All Year Round? [Cutting-Edge Technology!]" on the Nissui official website and Sakana-kun's official YouTube channel "Sakana-kun Channel - FISH BOY - Sakana-kun." The video introduces the appeal of "Kurose Buri," which is fully farmed by the Nissui Group.

"Kurose Buri" is yellowtail raised using the full-cycle aquaculture technology that the Nissui Group has cultivated over many years. Through planned egg collection, cultivation, and shipping, it can be enjoyed with rich fat content all year round. Furthermore, as a farming method that does not rely on wild fry, it contributes to reducing the burden on limited marine resources.

In the video released this time, Sakana-kun, who is active in a wide range of fields with his extensive knowledge of fish and approachable speaking style, will entertainingly introduce the secrets behind the deliciousness of "Kurose Buri." Sakana-kun will explain in an easy-to-understand manner from his unique perspective how full-cycle aquaculture can deliver delicious and high-quality yellowtail year-round, the importance of selecting and raising excellent parent fish, and how Nissui's unique chili pepper-infused feed supports the color retention of the bloodline, fat content, and firm texture.

Through this video, Nissui aims to inform more people about the deliciousness of "Kurose Buri" and the sustainable utilization of fishery resources through full-cycle aquaculture.
