    The Fisheries Research Agency in Yokohama, Japan has become the world's first to breed 2nd generation cultivated eels from sperm and eggs collected from eels that were artificially raised. This development could lead to lessen the impact on wild eel populations that have plunged more than 90 percent in the last 30 years.

    The current cultivation system requires catching glass eels, or juvenile eels, and raising them, but a branch of the research agency succeeded in raising glass eels from artificially bred larval fish in 2002, also for the first time in the world.


    After these glass eels became 45 cm to 70 cm long, the agency gave them hormones to stimulate sexual maturation to extract sperm and eggs earlier this year, and succeeded in getting some 250,000 fertile eggs on March 26 through artificial insemination.


    Some of them hatched the following day and are now growing thanks to feedings by the researchers since April 2, according to the organization.

    If you're talking about the recent Great Barrier Reef incident, that was China, not Japan.

    Also, if you think Japan hasn't done anything involving mixing science and marine life to help the environment, you're seriously mistaken.
