Researchers at the University of Washington Seattle came up with simple yet brilliant idea o how to track ocean health - they opened old cans of salmon and counted the worms imbedded in the seafood.
These worms - anisakids - are often present in such fish and do not pose a health hazard to consumers.
So why do it? The researchers figured that the presence of these parasites would give us a glimpse into ocean health; a healthier ocean would probably see more of these little parasites than an unhealthy ocean.
So what did they find?
"The team's findings, published in Ecology & Evolution, showed that anisakid levels increased in chum and pink salmon between 1979 and 2021. In coho and sockeye salmon, parasite levels remained steady.
"Anisakids have a complex life cycle that requires many types of hosts," said Mastick, who is lead author on the paper. "Seeing their numbers rise over time, as we did with pink and chum salmon, indicates that these parasites were able to find all the right hosts and reproduce. That could indicate a stable or recovering ecosystem, with enough of the right hosts for anisakids."'
Which means the oceans have been getting healthier DESPITE rising carbon dioxide levels in the Earth's atmosphere (and supposedly in her oceans). So what does that tell us class? If anything carbon dioxide is GOOD for the biosphere!
At a minimum it tells us the panic over rising carbon dioxide levels is overblown and that it's certainly good for these little worms.
We we're told that ocean acidification was killing all the marine life but it appears to be just the opposite; plenty of worms and plenty of hosts for those worms. It's a golden age in the sea for salmon, anyway, and the worms they carry.
Just one more piece of evidence against the panic-laden climate change hysteria. I almost feel sorry for the alarmists; nothing predicted by their theory has come to pass.
