Dutch Harbor lands more seafood by value than any U.S. port. Here's what its AIS traffic reveals.
Unalaska’s Dutch Harbor has been America’s number-one fishing port by value for decades — the gateway to the Bering Sea pollock and crab fisheries made famous by Deadliest Catch.
AIS makes the rhythm of the fishery visible: catcher-processors steaming in to offload, tenders shuttling to the grounds, and tankers and cargo ships rotating through the dock. Our congestion score benchmarks today’s vessel count against a 30-day baseline so operators know if the harbor is slammed before they call the dispatcher.
Pollock A-season (January–April) and snow-crab openings drive sharp spikes in arrivals. Watching port traffic over a season is a leading indicator of landings, fuel demand, and dock pressure.
