JoshuaInNippon writes "Japanese scientists at the National Research Institute of Aquaculture, Fisheries Research Agency have reported that they successfully completed an artificial cultivation cycle for unagi, or eel — a world first. Unagi is a traditional delicacy in Japan, and can commonly be found in baked form at sushi restaurants. The fish has long been caught either matured, or still young and then fattened on farms. Sadly, as a result, natural stocks of unagi have plummeted in recent years. However, the research news indicates a future method to completely farm breed the tasty creature in mass quantity. Good news for sushi lovers, Japanese businesses, and wild eel alike."
