Kindai University (or Kinki University), which sells the bluefin tuna it farms, said it will also aim to achieve "full-cycle" aquaculture of eels, meaning incubating and cultivating eels and then obtaining second-generation eels from them, for commercial use.
In 2002, Kindai University became the first institution in the world to achieve full-cycle aquaculture of bluefin tuna. The fish has gained popularity as "Kindai tuna."
The university said about 30 eel larva, which were artificially incubated on Sept. 12 at its research facility in Wakayama Prefecture, have grown to about 2 centimeters over 50 days.
The university is separately growing around 1,100 larva. If things go smoothly, some of these are expected to grow to a marketable size next spring.

In a bid to cut back on aquaculture costs and workloads, Kindai will try to develop a feed that is less likely to pollute water, according to the university.
