Increasingly Acidic Seas Threaten #Oyster Farming
Researchers and hatcheries are exploring new ways to protect #shellfish in the #Pacific Northwest, although Trump budget cuts may thwart their efforts.
Eighteen years ago, farmed oyster larvae began disappearing in mass die-offs, mystifying hatchery managers in the Pacific Northwest and threatening a thriving part of the region’s economy.
Up to 90% of the farmed Pacific oysters were being wiped out.

Mussel power: how an offshore #shellfish farm is boosting marine life theconversation.com/mussel-pow

"Over many years, the studies have shown how some #mussels from the farm have fallen to the seabed and regenerated lost shell reefs. The farm has also boosted populations of #crabs, #lobsters, #scallops, #starfish, #fish, conger #eels, #sharks and #rays... By creating structure and excluding the damaging effects of bottom-towed fishing, offshore #MusselFarms can restore degraded #fishing grounds"

Mussel power: how an offshore shellfish farm is boosting marine life.

Mussel farming provides a sustainable alternative protein source for human diets, because mussels filter feed on plankton and do not have to be fed wild-caught fish.

Researchers have found that one offshore mussel farm is boosting marine biodiversity and regenerating the seabed.

#DomoicAcid can also accumulate in #shellfish & small #fish that feed on the #algae, leading to poisoning in larger #marine animals & humans who consume contaminated #seafood.

Addressing the urgent need to monitor the impact of harmful #AlgalBlooms on #MarineSpecies requires collective strategies. The destructive #California #wildfires, which have contaminated our #oceans & are threatening #MarineLife, serve as a critical call to action for collaborative efforts to protect marine environments….

#China wants to restore the #sea with high-tech marine ranches
China is the world's top #fish consumer and is spending billions on technology designed to restock #oceans.
Since 2015, China has built 169 “national demonstration ranches” and scores of smaller-scale facilities, which collectively have laid 67 million cubic meters of artificial #reefs and planted an area size of Manhattan with #seagrass, while releasing at least 167B juvenile fish and #shellfish into ocean.

"Spanish fishers in #Galicia — Europe’s main source of #shellfish and the biggest producer of #mussels in the world — are reporting a “catastrophic” collapse in shellfish populations due to the #climate crisis.

Some shellfish stocks have plummeted by 90 percent in just a few years."

Shells - leave them by the shore

"This summer, please leave the sea shells by the seashore. Someone needs that shell more than you. For native wildlife, both occupied and unoccupied shells provide important shelter and sources of calcium and grit."

"If you absolutely must pick something up and take it home, please pick up some of the vast amount of plastic found on Australian beaches."
