As Alaskan Waters Warm, Market Squid Extend Their Reach Northward

This article discusses how warming oceans are affecting opalescents, also known as market squid. They are moving north, showing up in waters previously considered too cold for them. Fishermen are paying attention. But they are also noticing that other species are in severe decline. Populations of valuable species like king salmon and Pacific grey cod have fallen to as little as one-tenth of even their 2015 levels. With those populations at historic lows, the Alaska Department of Fish and Game now bans their catch during parts of their historical fishing season.
