In a quest to preserve endangered species japan researchers are producing endangered species from other plentiful species through surrogation.Papa salmon + mama salmon = baby trout!!
Goro Yoshizaki, a Tokyo University marine scientist is leading the research..
what he did is
he used"salmonids," a family that includes both salmon and trout.
he engineered salmon to be sterile.He injected newly hatched salmon with stem cells destined to grow into sperm that he had culled from male rainbow trout.
Once they were grown, 10 of 29 male salmon who got the injections produced trout sperm, called milt!
Those new trout grew up able to reproduce.
