Denying climate change and it's effects are beyond silly - irresponsible, IMHO. That's why I keep posting the peer-reviewed science on the matter. Read the science.
State of Canadian Pacific Salmon: Responses to Changing Climate and Habitats
ABSTRACT
At DFO’s first State of the Salmon meeting in 2018, scientists concluded that Canadian Pacific salmon and their ecosystems are already responding to climate change. Northeast Pacific Ocean warming trends and marine heatwaves like “The Blob” are affecting ocean food webs. British Columbia and Yukon air and water temperatures are increasing and precipitation patterns are changing, altering freshwater habitats. The effects of climate change in freshwater are compounded by natural and human-caused landscape change, which can lead to differences in hydrology, and increases in sediment loads and frequencies of landslides. These marine and freshwater ecosystem changes are impacting Pacific salmon at every stage of their life-cycle. Some general patterns in Canadian Pacific salmon abundances are emerging, concurrent with climate and habitat changes. Chinook numbers are declining throughout their B.C. and Yukon range, and Sockeye and Coho numbers are declining, most notably at southern latitudes. Salmon that spend less time in freshwater, like Pink, Chum, river-type Sockeye, and ocean-type Chinook, are generally not exhibiting declines. These recent observations suggest that not all salmon are equally vulnerable to climate and habitat change. Improving information on salmon vulnerability to changing climate and habitats will help ensure our fisheries management, salmon recovery, and habitat restoration actions are aligned to future salmon production and biodiversity. To accomplish this, we must integrate and develop new research across disciplines and organizations. One mechanism to improve integration of salmon-ecosystem science across organizations is the formation of a Pacific Salmon-Ecosystem Climate Consortium, which has been recently initiated by DFO’s State of the Salmon Program.
The Naknek-Kvichak fleet hauled in the second million-fish catch. Nushagak was just under a million, and yesterday’s daily catch across all districts was over 2.6 million. The run in the bay is at almost 20 million fish so far, and there are an estimated 650,000 fish in the rivers across the bay.
The increase in Bristol Bay sockeye has been associated with a warming bering sea increasing the survival of sockeye. That same warming bearing sea has been associated to the crash in cod stocks as well as the crab biomass moving further north.
