    Information age. Just start a rumor they caught more than fish.
    Something incurable! Galapagos Revenge. Makes Montezuma's revenge seem like a kids birthday party.
    They won't be allowe to land anywhere, not even home to China!

    Well why then in my area in the lower Chesapeake bay are there so many shellfish barnacles growing on everything. They are not being dissolved.
    It is like barnacle plague and they are also very good filter feeders. In the summer the water becomes more cloudy with much microscopic life, algae etc... in the winter the water clears up becuase it is cold. I do agree that there are less fish around than 30 years ago. But there are many blue crabs, no slow down for them.

    We have new dock pilings 4 years old already having several pounds of oysters taking up residence.

    Sharks Are Becoming Functionally Extinct Around The World

    No sharks were detected on any of the reefs in the Dominican Republic, the French West Indies, Kenya, Vietnam, the Windward Dutch Antilles and Qatar. Only a combined total of three sharks were observed during more than 800 survey hours in these locations.

    Shark finning: why the ocean's most barbaric practice continues to boom

    A 2018 survey by the foundation found that 85% of the city’s Chinese restaurants still sell shark fin dishes. Shipments come in daily, often falsely labelled to dodge port checks. “When I saw that over 100 million sharks are being killed every year and 50% of that global trade was coming right through Hong Kong I was blown away. It’s a global problem that we’re dealing with. In the last 50 years we’ve lost as much as 90% of some shark populations,” says Richey.

    Red Sea corals' heat tolerance offers hope for climate crisis

    .....Half the world’s coral reefs are thought to have died in the past three decades, and up to 90% of existing coral reefs may die by the middle of the century, according to research from February.

    Yet the coral [from the Red Sea] in the experiment at the University of Eilat survived, even as temperatures were raised to five, then six, then seven degrees. “They even showed improved physiological performance at higher temperatures,” says Maoz Fine, the professor of marine science who led the research. “At first we weren’t so sure we were doing everything right, experimentally.”....

    The implications for coral reefs elsewhere in the world are still being studied. Transplanting hardy coral species to other reefs has not generally worked in the past, says Meibom. “The salinity of the water and the ecosystem of microbes is different,” he says. “A few species survive, but they’re not happy, and many of them die.”.....

    When you consider how much of the world's coral is clustered around regions like Polynesia, the "Ring or Fire", you have to believe that temperature isn't the reason coral reefs are dying.

    Volcanic activity can cause regional ocean and ground temperatures to rise even when there is no eruption of lava. The Earth spins within the fluctuating gravitational fields of other astral bodies, this causes movement of continental plates and thus, a certain amount of heat is generated from the friction of their movement against each other. I've seen video of coral life on the edges of midocean ridges.

    As filter feeders, they are probably very sensitive to pollutants in the water. I'm hoping we move more quickly into electric propulsion. I would like to see if significantly reducing refined oil spillage into our oceans will have a positive affect.

    Citation, please, for your temperature change assertions.

    "The mid-ocean ridges are the earth’s largest volcanic system, accounting for more than 75% of all volcanic activity on the planet. The heat from this volcanism is dispersed by hydrothermal circulation of seawater. Hot seawater venting from the seafloor supports strange benthic communities that have evolved to survive by using the hydrogen sulphide dissolved in the hot fluid."

    To be clear, I am not asserting that volcanic activity is the cause of ocean or global warming, only that it warms regions of the ocean above normal or average temperatures.
