Juvenile Chum salmon
Image of the juvenile Chum salmon (Oncorhynchus keta) that first confirmed successful reproduction of Pacific salmon in the North American Arctic. This fish was captured on August 10, 2017, in Jago Lagoon, Arctic National Wildlife Refuge, Beaufort Sea, Alaska, U.S.A.

The catch from a fyke net set near Kaktovik, Alaska
Biologists identify species, count, measure length, and release thousands of fish each year to understand how fish use nearshore habitats.

A fyke net set to catch nearshore fish near Kaktovik, Alaska
A fyke net or fish trap used for continuous sampling of nearshore fish in shallow waters. Fish swimming along the beach are stopped by a small-mesh net that guides them in to one of these two underwater fish traps that are set side by side. Researchers visit nets at least once a day to identify, count, and release fish.

Underwater image of fish captured by a fyke net
An underwater image of fish captured by a fyke net near Kaktovik, Alaska, Beaufort Sea, USA. The small silver fish with dark backs are young-of-year (age-0) Arctic cisco (Coregonus autumnalis) and the flatfish are Arctic flounder (Liopsetta glacialis).
