November 15, 2024 — Researchers looking to estimate biomass of multiple Alaska fish species say it is now possible to estimate fish biomass for more than one species at the same time using environmental DNA found in sea water.
In a report released by NOAA Fisheries on Oct. 31, Kimberly Ledger – a research biologist with the Auke Bay Laboratories of the Alaska Fisheries Science Center and lead author of the study – said researchers had learned they could accurately quantify species composition and estimate biomass for different species of cod and pollock at the same time using eDNA.
