NPAFC Workshop to Focus on Climate Change’s Impact on Salmon, Trout

A two-day workshop planned for June 4-5 in Vancouver, British Columbia by the North Pacific Anadromous Fish Commission (NPAFC), is to focus on abundance and distribution trends of Pacific salmon and steelhead trout in a changing North Pacific Ocean. The workshop was announced Nov. 30. Its objectives include a range of topics, from improving knowledge of the migration, growth and survival of salmon and their environments, to discussing application of new and development technologies and analytical methods to research and manage salmon. NPAFC has embarked on a new Science Plan to build on the previous international cooperative research that was conducted within the International Year of the Salmon (IYS). NPAFC officials said that the primary goal of the 2023-2027 Science Plan is to...

Studies Show Major Fish Populations Are Relocating to North, South Poles

Scientists at the University of Glasgow in Scotland say their research shows that the majority of fish populations in the world’s oceans are responding to climate change by relocating towards colder waters nearer the north and south poles. This latest study, released on May 31, identifies many marine fish populations shifting toward the Earth’s poles or moving to deeper waters, all in an effort to stay cool. For much of marine life water temperature affects critical functions such as metabolism, growth and reproduction. Various marine species have a very narrow livable temperature range. As a result, marine life changes caused by global warming have been up to seven-fold faster than animal responses on land. This latest study examined data on 115 species spanning all major oceanic regi...

ComFish Alaska 2023 Takes On Climate Change, Legal Challenges to State’s Fisheries

Participants in ComFish Alaska 2023, undeterred by a spring snowstorm that halted jet traffic in and out of Kodiak for a day, tackled climate challenges to fisheries, including plastics pollution and prospective economic and environmental benefits of the mushrooming kelp mariculture efforts. The state’s biggest and longest-running commercial fisheries trade show, which began in a borrowed Alaska National Guard wall tent in 1980, incorporated into its March 16-18 program in Kodiak a mix of presenters ranging from harvesters, fisheries managers, federal and state legislators to historians and experts in marine debris and kelp mariculture. The event also featured 46 trade show booths offering fishing marine supplies, vessel permits and sales, expertise in satellite technology, health care...

Study Notes Potential Impact of Climate Change on Maritime Boundaries

A new study released Sept. 12 by University of Sydney researchers concludes that the rules for atolls and coral reefs in international law of the sea, already subject to interpretation due to their shifting nature, will be under greater stress as sea levels rise and ocean acidification disrupts reef integrity. These reef islands, found across the Indo-Pacific are already growing and shrinking due to complex biological and physical processes yet to be fully understood, and now climate change is leading to new uncertainties for legal maritime zones and small island states, according to the study, which was published in Environmental Research Letters. Thomas Fellowes, a postdoctoral research associate at the university and the lead author of the paper, called the situation “a perfec...

UBC Urges Strong Action to Mitigate Climate Change

A new study released by the University of British Columbia is projecting the impact of different global temperature increases and ranges of fishing activity will have on biomass, or the amount of fish by weight in a given area, from 1950 to 2100. The simulations suggest that climate change has reduced fish stocks in 103 of 226 marine regions studied, including Canada, from their historical levels, and that these stocks will struggle to rebuild their numbers under projected global warming levels in the 21st century. According to lead study author William Cheung, a professor at Canada’s Institute for the Oceans and Fisheries, more conservation-oriented fisheries management is essential to rebuild over-exploited fish stocks under climate change. But that alone is not enough, Cheung ...

NOAA Extends Comment Period on Draft Climate Science Action Plans

Federal fisheries officials have extended to Friday, July 29, the deadline for comments on the proposed NOAA Climate Science Regional Action Plans to make fisheries and protected resources more resilient to climate change. Copies of the draft regional action plans are available for the Western Region, including California, the Beaufort and Chukchi seas, Eastern Bering Sea and Gulf of Alaska. The initial Western Regional Action Plan, released in 2016, focused on implementing NOAA Fisheries’ Climate Science Strategy (NCSS) in the California Current Large Marine Ecosystem over three to five years. The current draft builds on previous efforts and describes proposed actions in 2022-2024 to provide decision makers with information to prepare for and respond to changing conditions in th...

Study: Climate Change Results in Fewer Productive Fish Species

Study: Climate Change Results in Fewer Productive Fish Species

A new Rutgers University study finds that as temperatures warm during climate change, predator-prey interactions could prevent some species from keeping up with conditions where they could thrive, resulting in fewer productive fish species to catch in the future. The study, published April 13 in the biological research journal Proceedings of the Royal Society B, presents a mixed picture of ocean health. Not only could large species and commercially important fisheries shift out of their historical ranges as climate warms, but they would likely not be as abundant even in their new geographic ranges. For instance, a cod fisherman in the Atlantic might still find fish 200 years from now but in significantly fewer numbers. According to study coauthor Malin Pinsky, the findings sugg...
