AFSC Study Looks at Range of eDNA in Marine Fisheries Management
New research by the Alaska Fisheries Science Center (AFSC) in Juneau examines the influence of distance and tides on distribution and concentration of environmental DNA from chum salmon in net pens in Southeast Alaska.
It’s another piece of the puzzle as researchers work to understand the overall impact of changing climate conditions on fisheries in the ocean.
This study, AFSC research geneticist Diana Baetscher said, addresses one of the critical knowledge gaps in applying eDNA to marine fisheries management.
“The idea here is we are able to use eDNA to understand where the fish are,” she said. “What we did with the chum hatchery net pen in Juneau was an experiment to determine where we no longer detect this eDNA. It is just a piece of information floating around in the water...
