#Farmed production of some #fish—and #seaweed—is soaring
According to the #UN's Food and Agriculture Organization (#FAO), nearly 99 million tonnes of aquatic animals (fish, mollusks like oysters and mussels and crustaceans like prawns) were farmed around the world in 2023, five times more than three decades ago.
Since 2022, the farming of aquatic animals has been steadily overtaking #fishing around the world—but with large disparities from species to species.

Seaweed packaging is shifting single-use plastic out of stadiums.

Notpla started with its two French and Spanish founders, Pierre Paslier and Rodrigo Garcia Gonzalez, experimenting in their student kitchen while at Imperial College London.

Now, the venture has replaced more than 21 million items of single-use plastic across Europe, and is aiming to displace 1 billion units by 2030.

Giant clone of seaweed discovered in the Baltic Sea https://phys.org/news/2025-03-giant-clone-seaweed-baltic-sea.html

"a small, bushy form of #seaweed that was previously thought to be a separate species is a clone of bladderwrack. The clone has formed new populations by dispersing fragments of an original female plant with the currents and growing into new individuals. The clone spreads over more than 500 km of the coast of the Bothnian Sea, from Öregrund to just south of Umeå, and may be the world's largest clone of any organism"

How I’m turning #seaweed into #biofuel for #cars on #Barbados
Mechanical engineer Legena Henry converts sargassum and rum-distillery waste water to produce sustainable #naturalgas for vehicles.
“All the islands in this region of the Caribbean have a sargassum problem and a rum wastewater problem—and ultimately a #climatechange problem,” Henry told Nature. “This solution is a win-win-win.”

Rockweed soup? How researchers are trying to boost use of native seaweeds
Researchers at Acadia University asked taste testers to try soup made with Irish moss and rockweed. The results? There's still more work to be done to minimize "off-flavours."

Green staghorn coral may be more likely to survive ocean warming if crabs are around https://phys.org/news/2025-02-green-staghorn-coral-survive-ocean.html

"predation by #starfish led to wounds that bled mucus, which in turn attracted the hoof-clawed #crab... the #crabs fed on the mucus but did not harm the coral... they also fed on nearby #seaweed, typically the vectors for infectious #bacteria, which led to infection prevention in the #corals... coral that were protected by the crabs were 60% less likely to suffer tissue loss"

Did you know that some research believes that #ancient #Europeans regularly ate #seaweed?

#Aquatic #plant eating is often connected to Asia. But in 2023, researchers found evidence of widespread consumption of seaweed during the transitional years between hunter-gather culture & farming.

What's more is that Europeans kept eating seaweed into the early #MiddleAges - perhaps recognising its nutritional value.

Why have aquatic foods been lost in western diets?

Good question.
