"Environmental DNA" or eDNA, strained from one-litre samples drawn weekly from New York's East and Hudson rivers over six months last year, revealed the presence or absence of several key fish species passing through the water on each test day.
The weekly data snapshots created a moving picture that largely reinforced and correlated with knowledge from migration studies conducted over many years with fishnet trawls.
The Rockefeller University study, published on Wednesday in PLoS ONE, pioneers a way to monitor fish migration that involves a fraction of the effort and cost of trawling, all without harming the fish
