increasingly forced to go after deep-water fish. But the habits of species that
live deep down cannot be studied using conventional methods, which involve
tagging fish, and this makes it hard to get the information needed to ensure
these new fisheries are managed sustainably.
Now engineers in Iceland have come up with a device that promises to remedy
the problem. Star-Oddi, a marine equipment manufacturer based in Reykjavik, has
developed equipment that tags fish at depths down to 1000 metres.
Researchers need to track fish to map their daily…
