Bluefin tuna aquaculture must still overcome a number of technical hurdles, including those related to the hatching of fertilized eggs from fish born through artificial insemination. But improving prospects for the business are causing a surge in stock prices for the early pioneers and companies that provide ancillary services or develop related technologies, the Nikkei Asian Review reports.
Since Tokyo-based Maruha Nichiro commercialized full tuna farming in 2015, a number of Japanese companies have jumped into the market.
Kyodo Shiryo and Nippon Formula Feed Manufacturing merged in late 2014 to form Feed One, which now has partnered with Kyokuyo to start farming. The enterprise, which expects to ship its first batch of fully farmed bluefin in November, has seen its stock – traded on the Tokyo Stock Exchange — soar by 94% since the end of 2016, according to the business news service.
Meanwhile, Kyokuyo shares are up 34% and Maruha Nichiro’s stocks have climbed 10%.
