New Zealand scientists hunt elusive eel spawning sites using DNA and tags, facing challenges like deep dives and pollution.
Scientists in New Zealand are working to uncover where shortfin and longfin eels spawn, using DNA from water samples and satellite tags to track their deep-sea journeys, though challenges like tag failure and deep dives hinder progress.
Spawning likely occurs at 100 to 140 meters, but exact sites remain unknown, with evidence suggesting multiple locations possibly linked to both New Zealand and Australia.
Despite setbacks, including eel predation and pollution harming habitats, researchers continue seeking the elusive spawning grounds.
