What is it?
A new way of servicing our ever-increasing demand for tuna.
Kindai Tuna is a specific farm-raised fish grown in Japan in an effort to provide a more sustainable and less environmentally-intrusive fish to the market. This is the only practical solution in maintaining the sustainability of the wild Bluefin Tuna population in the world. As widely known, wild Bluefin Tunas are on World Wildlife Fund’s list of species in danger of extinction. The groundbreaking techniques used for raising Kindai Tuna is the answer to continuing to service demand.
Where does it come from?
Plummeting wild populations of Bluefin Tuna meant the industry needed to change.
With wild Bluefin Tuna on the verge of extinction, Japan’s Kinki University put their efforts in a new form of farming this desired fish. Scientists were able to breed tuna through hatched eggs, rather than trapping juvenile fish from the ocean like other farming practices which ultimately provides zero benefit to the depleting natural population.
Through the development of a brood stock and creating an atmosphere for optimal spawning, the University has made strides toward a sustainable solution for the industry.
What are the benefits?
Low population-density, no drug enhancements and lower levels of mercury.
Much like the taste benefits of free-range chickens, Kindai tuna is of higher quality and better taste profile than other farmed fish because of the low-density population farming methods. This also allows the University to avoid growth-enhancing drugs in order to produce fish as large as 200lbs.
In addition, Kindai Tuna has been proven to contain lower levels of mercury than wild and traditionally-farmed Bluefin Tunas. This is accomplished through:
Using feed sources consisting of younger fish, a practice not followed by other farming techniques - younger fish naturally have lower mercury contamination levels than older fish who have been exposed for longer periods of time.
The Kindai technique allows for the fish population to require a lower-calorie diet than wild tuna - they do not exert additional energy needed by wild tuna to fuel constant swimming in the search for food and for the avoidance of predators.
