Decades of DNA in the Ocean Depths Could Help Track Fish Populations

Read the full story in Hakai Magazine.

There may be plenty of fish in the sea, but how many did there used to be? The answer to that question is lurking in DNA hidden at the bottom of the ocean.

Japanese scientists who analyzed DNA trapped in seafloor sediments have now shown, for the first time, how this preserved genetic material can be used to chart changes in fish populations over centuries. The new technique, reported in a recent study, could be used to help understand population dynamics of marine species.
