Warming ocean temperatures are causing massive changes for fishermen, some of which may force them out of business, according to several recent stories examining the impacts of climate change on the fishing industry. Various valuable fish species all around the U.S. and the globe, from Alaska to the Gulf of Mexico to the North Atlantic, are shifting to the north to avoid warmer waters and also are being impacted by new threats caused by ocean warming and acidification.
The Wall Street Journal chronicled the increasing challenges for the crews of the fishing vessel Oracle that catches halibut in the Deadliest Catch waters of the Bering Sea off Alaska. This past fall, the Oracle twice sailed 800 miles north from the seaport of Dutch Harbor in the Aleutian Islands, before finding the halibut that a decade ago lived several hundred miles closer to home. Each voyage took twice as long and yielded half as many fish.
As Inside Climate News explained, “From cheap food imports to hurricanes fueled by a warming planet, these systems support, or strain, the tapestry of what it takes to get seafood to the dinner plates of diners.” However, not everyone is a loser in this warming scenario — the Wall Street Journal describes how “[o]ff Rhode Island, newly booming fisheries include not just black sea bass but also squid and Jonah crab, an edible species with big, dark-brown claws.”
Why This Matters: Warming waters that shift fish populations make a barely viable business downright impossible for many small and medium-sized fishing operations. Not to mention the additional fuel and time it takes to chase fewer fish, that are now found farther from ports. Watching this play out is painful in U.S. fishing communities, but for many parts of the world, it could become a real food security crisis. The U.S. government currently is very lethargic in changing its fisheries management schemes even as the evidence of shifting fish populations grows. Given the challenges of climate change, a more engaged approach to fisheries management that takes climate change into account is needed. It will benefit the fishermen and the fish populations as well.
By Amy Lupica, ODP Daily Editor Research has found that smoke and ash from Australia’s massive 2019 and 2020 wildfires triggered widespread algal blooms thousands of miles away. The Duke University-led study reported that the phenomenon could be effective in sequestering additional carbon, but algal blooms can also be toxic and devastating to wildlife and […]
You may remember our special Earth Day interview with Friend of the Planet, Brian Skerry. Well, he’s in the news again, but this time for working on the Emmy Award-winning documentary, Secrets of the Whales. The four-part series explores the complex lives of five whale species, including orcas, humpbacks, belugas, narwhals, and sperm whales. […]
By Ashira Morris, ODP Staff Writer A motion rejecting deep-sea mining was largely supported by delegates at the IUCN World Conservation Congress, currently meeting in Marseille, France. The motion calls for a moratorium on extracting minerals from deep below the ocean surface, as well as reforms for the International Seabed Authority, which is responsible for […]
