Alaska fishermen struggle with warming ocean

Warmer water is moving Alaska's fish, and fishermen must go further for their catch. So far they're still finding fish, but the future is uncertain.

Warming is affecting almost everything that's caught in Alaska, the source of about half of US-caught seafood. The changes aren't limited to fish, blogfish brought you the news on sea ice and mammals affected by warming.

These changes have Alaska's politicians on the leading edge of US politics, seeking solutions.

Some groups doubt warming is the problem and claim instead that changes in fish, birds, and mammals, "are likely due, in large part, to the massive Alaska pollock fleet, which is the nation's largest fishery." Fishing is a cause of changes in Alaska's oceans, and so is warmer water.
