Most people, even those who know a thing or two about oysters and may perhaps enjoy eating them, have no idea that the sweet and buttery bivalves they are slurping down in San Francisco or Vancouver are not the native species of the West Coast but Japanese imports…It is only on rare occasions at certain bougie establishments that you might encounter the much-smaller Olympia oyster (Ostrea lurida) on the menu, a Proustian remembrance with its miserly portion of meat and coppery taste…

Scientists all along the Atlantic and Gulf coasts are trying to bring oyster populations back, and not just because they’re a popular food. Oysters are also important for healthy coastal ecosystems. And researchers are now studying how creating new oyster reefs could help fight climate change by sequestering carbon…

The World Is Running Out of Male Sea Turtles – Science Alert

Green sea turtles are already an endangered species, mainly due to humans hunting them, harvesting their eggs, degrading their habitats, or entangling them in garbage of some kind. But they also face another, more insidious threat from people: the loss of male hatchlings from the species…that this is partly caused by rising temperatures due to climate change – but a new study has now unveiled another human-caused problem driving this trend. Certain pollutants may promote feminization in sea turtles, explains lead author Arthur Barraza, a toxicologist with the Australian Rivers Institute at Griffith University…

Research Confirms Link Between Snow Crab Decline and Marine Heatwave – NOAA Fisheries

“During the marine heatwave, snow crabs faced a triple threat,” said lead author and Alaska Fisheries Science Center stock assessment scientist Cody Szuwalski. “Their metabolism increased, so they needed more food; their habitat was reduced so there was less area to forage; and crabs caught in our survey weighed less than usual. These conditions likely set them up for the dramatic decline we saw in 2021…”

Seaweed is mucking up beaches. This robot could stop it — and fight climate change – NPR

Sargassum sacs (by John Turnbull CC BY-NC-SA 2.0 DEED via Flickr).

In shallow waters, sargassum can smother coral reefs and alter the water’s pH balance, killing off local seagrasses and mangroves. It can choke boat motors, constricting local fishing yields if not cutting off whole marinas. Sargassum once clogged a desalination plant so badly that residents of the U.S. Virgin Islands were told the drinking water may not be safe…
