  1. (Note: this is an annual, regular quarantine order of shellfish in California, due to "red tide" possibility in warmer months. At some point, they're going to have to extend this on either side of the normal annual quarantine, if SSTs keep on rising)

  2. Red, red tide
    Goes to my head
    Kills all the fish that I
    Won't eat so

    Red, red tide
    It's all over you
    Blows through the air, we're done
    Shortness of breath I know
    Shortness of breath I know

  3. Algal Toxins and Wildlife Health

    By National Wildlife Health Center September 30, 2019

    "Harmful #AlgalBlooms (#HABs) have the potential to harm fish and wildlife, domestic animals, livestock, and humans through toxin production or ecological disturbances such as oxygen depletion and blockage of sunlight.

    "To investigate the effects of algal toxins on wildlife, the USGS National Wildlife Health Center (NWHC) has examined over 300 dead animals collected during freshwater and marine #HAB events since 2000. Varying levels of algal toxins were found in over 100 of these animals. In some cases, the history, clinical signs, and high toxin levels have allowed scientists to attribute mortality to algal toxicosis. Recent events have included Kittlitz’s #murrelets (Brachyramphus brevirostris) in Alaska that died after consuming sand lance (Ammodytes hexapterus) high in #saxitoxin (Shearn-Bochsler et al. 2014), #GreenTreeFrogs (Hyla cinerea) in Texas with suspected #brevetoxicosis in association with a #RedTide event (Buttke et al. 2018), and #LittleBrownBats (Myotis lucifugus carissima) in Utah found dead during a HAB event at a reservoir commonly used for recreation and as a source of municipal #DrinkingWater (Isidoro-Ayza et al. 2019).

    "In other cases, algal toxins have been detected in wildlife, but their contribution to mortality remains unclear. Part of the reason these detections have been difficult to interpret is that the toxic dose of many algal toxins in wildlife species is unknown and the microscopic lesions (if any) particularly in birds, have not been well described. To better understand the effects of these toxins the NWHC is conducting laboratory exposure trials to determine the lethal dose of toxin in birds and to examine the repeated exposure of waterfowl to sub-lethal toxin ingestion. In addition to exposure trials, NWHC is undergoing a retrospective review of previous detections of algal toxin from NWHC’s case archives to examine demographic, spatiotemporal, and diagnostic features associated with wildlife exposure to algal toxins."

    Disoriented pelican found on Marco Island may have red tide poisoning, experts say

    By CNN
    May 23, 2024

    A brown #pelican discovered on #MarcoIsland last week is presumed to have red tide poisoning, according to the Conservancy of Southwest Florida.

    "'Typically, we first get the notion that red tide is around when birds are sick,' said Dr. Michael Parsons, of the Water School at Florida Gulf Coast University.

    "The seabird was spotted disoriented on the beach, according to a release. Despite those symptoms, which are common with the #neurotoxic algae, no red tide has been detected in our area, per the Florida Department of Health in Collier County.

    "'We have no signs of red tide around, FWC is aware of this situation and will be monitoring it more closely,' Parsons said."

  15. What’s Killing #Endangered #Sawfish in #Florida?
    Off #FloridaKeys fish — jacks, snook — swim in spirals or upside down in shallow waters of #Atlantic and #GulfofMexico. So were #stingrays and the occasional #shark. Then, endangered sawfish started dying. Scientists are racing to figure out why but have not yet figured out what is going on. They have ruled out a few potential causes, including #redtide, toxic #algalbloom that has led to past kills.

  16. @failedLyndonLaRouchite It's a very good question! They are clearly super toxic to all sorts of things that impinge on human society, including in some cases humans themselves. But the chemical ecological question for what these polythers *really* do for the algae, is an open question. My hypothesis is prymnesin helps P. parvum hunt it's other little eukaryotes that it eats. (it is mixotrophic - both photosynthetic & predator). But dinoflagellates (i.e. #redtide in #florida) are not mixotrophic

  17. But what’s the big deal? Turns out prymnesin is in a class of “marine polyether biotoxins”, that are behind some of the most environmentally and health impacting harmful algal blooms out there. #Redtide in #florida Yup, same class. But we don’t know any… 🧵4/n

  25. Union of Concerned Scientists: The Hidden Costs of #IndustrialAgriculture

    Published Jul 11, 2008 Updated Aug 24, 2008

    Industrial farming is bad for the health of workers, eaters, and downstream neighbors. Here are some of its costly health impacts:

    #Pesticide toxicity. #Herbicides and #insecticides commonly used in agriculture have been associated with both acute poisoning and long-term chronic illness.

    • Water #pollution from #fertilizer runoff contaminates downstream drinking water supplies, requiring costly cleanup measures with an annual price tag of nearly $2 billion.

    • Loss of mid-sized #farms. Once the backbone of US agriculture, medium-sized farms are a dwindling breed, which means that fewer and fewer people make their living as farmers—a trend that has been bad for the economies of rural communities and farm states.

    • Harm to neighboring and downstream economies. Industrial agriculture can pack an economic wallop hundreds of miles from its origin—just ask local governments and utility managers who must install expensive equipment to remove fertilizer by-products from public drinking water supplies. Or ask people who make their living from fisheries or tourism on the Gulf of Mexico and elsewhere, where "dead zones" and toxic #algae blooms caused by farm runoff do damage with an annual price tag in the billions. CAFOs, too, create pollution problems that reduce livability and depress property values in surrounding communities.

  27. Florida beaches could be dealt a one-two punch of red tide and seaweed blob

    March 17, 2023

    A toxic algae bloom known as red tide is already killing fish along the Gulf Coast, causing a stench. Now, a massive blob of seaweed twice as wide as the United States is drifting across the Atlantic and could wash ashore in the coming weeks, creating an even bigger mess.

    "It could be two problems turning into a bigger one," said Mike Parsons, a marine science professor at Florida Gulf Coast University.
