Trout offspring from salmon parents — a conservation dream turned reality
Extinction need no longer be the end of the line – at least if you’re a salmonid fish – according to findings published recently in Science. A group of biologists at Toyku University of Marine Science and Technology, led by Goro Yoshizaki, has found a way to make one species of fish – in this case the salmon Oncorhynchus masou – create the sperm and eggs of another. They demonstrated the method, which involves microinjecting reproductive germ cells into surrogate fish larvae, by successfully producing apparently normal rainbow trout O. mykiss. With many salmonid species on the brink, the technique opens the door for countless conservation possibilities. Does it make you wonder if they’ll do the same for pandas one day?
