I guess a rotating bio-contactor is used to purify water. The more often it is used the better it is for our Earth. Yes, it is very, very good!

It goes back half a century to using carp pituitary injections into carp and other species creating a mini-business in carp pituitary extracts. Gonadotropins are great for getting ovulation when you want it. If you are doing specific crosses, there is a big advantage to getting ripe eggs and sperm on schedule. Moving to full life-cycle aquaculture on bluefin tuna may be the only way to prevent a total crash of the population. Fishing restriction would just up the price and illegal harvest. Aquaculture on a massive scale would cut the price and increase the quality -- aquaculture can harvest at a market maximum. To protect this species, a few 10's of millions of dollars into reproductive research would be appropriate. Hormone induced spawning spawning is a common aquaculture practice with a long history.

Neat bit of evolutionary conservation. Great article, by the way!
