But dams and other barriers to spawning grounds have disconnected that natural cycle, requiring fisheries managers to get creative to support salmon populations. It is now fairly common to transport salmon to and from spawning grounds by truck, boat, and even helicopter.

New technologies for analyzing DNA may transform how imperiled species are considered and managed for conservation protection, according to a study published today in the journal Science Advances and led by the University of California, Davis.
