DNA Sampling Next Frontier in Fish Counts
Keeping track of marine ecosystem health is expensive, as discussed in the last blog about the NOAA observer program. Monitoring what species are swimming or living where, and in what numbers often means teams of divers counting individual organisms in defined grids over a period of time. This provides a limited view because of the tiny section of ocean surveyed and just a brief window on activity in that grid at any time. And it costs a lot of money. Other approaches include dredging the ocean bottom to see what comes up, which doesn’t do the seafloor any favors. Read more “DNA Sampling Next Frontier in Fish Counts”
