  1. Now you seafood, now you don’t: $350k worth of oysters vanish without a trace in NSW
    By Kat Wong

    About 400,000 juvenile Sydney rock oysters were taken from an oyster farm on state’s mid-north coast earlier this year, police say

  2. 💁🏻‍♀️ TIL: 🦦🗽 A camera captured the first river otter sighting in the #Bronx River in over a century.

    Once treated as a city dumping ground, the #waterway lost #otters and #beavers to #pollution and #habitat loss. Decades of cleanup restored #oysters and beavers, now joined by this otter signaling active #ecosystem recovery.

  3. Have been caught up lately, doing good things but alternately busy and tired, sometimes both.

    Took these pics on the way to an appointment in town yesterday. The creek/stormwater drain level was lower than usual when i walked past (maybe a lower tide - it's close to the harbour), exposing a heap of oysters who'd decided urban life was for them. #NewcastleNSW #oysters

  4. New research has revealed that restored oyster reefs capture and bury much more nitrogen pollution than scientists had previously measured. 🦪🌊

  5. Oyster Reefs Sequester Nitrogen

    The US eastern seaboard was once blanketed with oyster beds, but overharvesting, pollution, and habitat destruction decimated the population. As filter-feeders, oysters are naturally good at cleaning intertidal zones, and the reefs they build by cementing themselves to one another provide valuable habitat for many species of fish. A new study shows that oysters are even more economically valuable than we knew, thanks to their ability to sequester nitrogen.

    Agricultural and industrial run-off carries nitrates into the ocean in high concentrations that trigger deadly phytoplankton blooms, which choke off oxygen levels for larger species like fish. One way to reduce nitrogen levels in the water is denitrification, a process where microbes break down the nitrate into, among other things, inert nitrogen gas. The surface of oyster reefs is one place where this happens. But nitrates that evade these microbes can also get trapped and buried by a growing oyster reef.

    To understand how much nitrogen an oyster reef can bury, researchers studied cores removed from restored oyster beds. Below the top ten centimeters (where microbes do their denitrification), nitrogen levels in the oysters increased, with a square meter of oyster reef, on average, sequestering 6 grams of nitrogen per year, comparable to the amount that microbes removed. But some oyster reefs outperformed others. In particular, intertidal flat reefs–which grow faster–buried more than twice the nitrogen of subtidal reefs.

    The team estimated that, in North Carolina’s Carteret County, oyster reefs sequester some 120,000 kilograms of nitrogen annually, at an economic value of over $3 million. (Image credit: J. Andrews/UNC-Chapel Hill; research credit: A. Smiley et al.; via Eos)

  6. Today is a better Thursday than most for any USians out there, because - hear me out - while it is true that you might live in a dystopian fascist hellscape where an ageing oligarchic minority is slowly but surely reshaping your future into one of unending indentured wage slavery - which I agree is pretty bad... at least tomorrow is Juneteenth!

    There are also #UnsolicitedNoods! Today's bowl of #momofuku #noodles features lots of #broccoli, #scallions, #oysters, and #cilantro.

  8. Recreational shellfish harvesters should be extra careful when collecting #oysters this weekend and next week to reduce their risk of illness. High temperatures are expected during the lowest tides of the year, creating conditions that can allow #Vibrio parahaemolyticus bacteria to grow quickly in oysters and increase the risk of illness from eating them raw or undercooked.

  9. #Trees, #grasses, #corals, and #oysters are foundational to the structure of an #ecosystem while they are alive. But new research shows that when they die — due to extreme events like storms, wildfires, or marine heatwaves — the physical remains of these species continue shaping the ecosystem.

  10. @NationCymru “Despite their small size, oysters make a big impact. Each adult oyster is capable of filtering approximately 200 litres of water a day – around a bathtub’s worth – helping to improve water quality and clarity” #oysters

  11. #Fukushima #Nuclear Power Plant starts 3rd round of #wastewater release, potentially impacting #seafood quality in U.S.

    By Belle Lewis - November 14, 2023

    "The #FukushimaDachii nuclear plant started its third release of nuclear wastewater on Nov. 2 as scientists warn that seafood products from the #PacificOcean could be #contaminated

    "Although the International Atomic Energy Agency approved the 30-year water release plan, scientists and civilians in nations bordering the Pacific Ocean have questioned the safety of the plan, especially as it relates to seafood.

    "In a press release approving of the plan, the IAEA stated, 'the discharges of the treated water would have a negligible radiological impact to people and the environment.'

    "#PaulDorfman, member of the Irish Government Environmental Protection Agency Radiation Protection Advisory Committee and chair of Nuclear Consulting Group, explained that some scientists have questioned IAEA’s approval of the water release.

    "'I and others are concerned by IAEA’s attitude,' Dorfman said. 'Normally even low levels of radioactive pollution will find its way into local seafood, one way or another.'

    "In 2020, #Japan exported 332,926 kilograms of frozen scallops to the U.S. Japan exports many fish products to the U.S.

    "Samantha Valeriano, a psychology student from Hawaii, said she eats seafood about once a week. She does not often think about where her food comes from but wants to be more cautious following the nuclear water release.

    "'I think I would be a little more cautious of what I ate, checking labels a little bit more,' Valeriano said. 'I would be conscious of what I ate and where it came from.'

    "As the People’s Republic of #China has imposed bans of Japanese fish exports, the #USA has supported the Japanese market by increasing fish purchases.

    "In a press release, the #UnitedStates Embassy and Consulate in Japan explained that military bases in Japan will carry Japanese seafood as a way to buoy up seafood markets and undermine the PRC’s ban.

    "'United States elected representatives and senior government officials have stood in solidarity with Japan during this baseless ban,' the statement said. 'Another step to help provide additional sales to counter the ban was to start selling Japanese seafood at the U.S. military facilities in Japan, both through the commissaries and mess halls.'

    "According to the statement, government officials like former speaker #KevinMcCarthy ate seafood from Japan as a testament to Japan’s safety standards.
    However, other U.S. agencies, like the National Association of #MarineLaboratories question whether accurate research was conducted by the IAEA and Japanese Government to determine safety of seafood products.

    "They explain that the lack of data on potential health impacts is a cause for serious concern.

    "'Many of the #radionuclides contained in the #accumulated waste cooling water have half-lives ranging from #decades to #centuries, and their deleterious effects range from #DNADamage and #cellular stress to elevated #cancer risks in people who eat affected marine organisms, such as #clams, #oysters, #crabs, #lobster, #shrimp and fish,' the statement reads. [Not to mention all the critters that feed off them! Bioaccumulation works up the food chain!]

    "Eve Nagareda, medical laboratory science major from Hawaii, shared she wants to avoid seafood from dumping grounds even if levels are considered safe.

    "'I think I would try to go as far as possible from it,' Nagareda said.

    "Kylee Wasano, pre-communications disorders student from Oahu, agreed. She explained she feels that she might already be consuming contaminated seafood.

    "'I feel like I already am eating that, and I just don’t know,' Wasano said. 'Anything that could expose you to (radiation) you should be considerate about.'

    "As organizations weigh safety concerns, scientists turn to the water release process to determine potential effects."
