2020年9月10日 · A “red tide” of blooming algae (the dinoflagellate Noctiluca scintillans) stretched more than 20 miles along the coast near LaJolla, California, in spring 1995. Such massive blooms can harm human health, coastal economies, and marine ecosystems.

WHOI scientists Dennis McGillicuddy and Ruoying He created a computer simulation of the historic 2005 toxic algae bloom in New England. Red denotes high algae concentrations; blue the lowest. Algal cells germinated from cyst beds in the Bay of Fundy and along the Maine coast. They were swept south and…

But since a toxic algae bloom known as "red tide" closed down shellfish beds from Maine to Martha's Vineyard - including the entire Chatham shellfishery - only empty skiffs bob in the soft waves of an inlet. On a recent morning, a lone clam digger stood in the parking lot, looking out at the fog. "Any news?"

2005年7月15日 · The historic bloom of toxic algae that blanketed New England's waters and halted shellfishing from Maine to Martha's Vineyard in the spring of 2005 is over. But scientists are now wondering if there will be an encore. Before departing, the algae likely left behind a colonizing population that may promote…

1999年4月19日 · The crayfish began fleeing from a "red tide" Wednesday night. The phenomenon is caused by an enormous concentration of red algae which starves the sea - and crayfish - of oxygen. It occurs because the bacteria that break-up the dead plankton on the sea-bed use up more oxygen in the decomposition process than normal simply because there is a ...

Human Illness Associated with Harmful Algae. Man is exposed principally to the naturally-occurring toxins produced by harmful algae through the consumption of contaminated seafood products. The most significant public health problems caused by harmful algae are: Amnesic Shellfish Poisoning (ASP) Ciguatera Fish Poisoning (CFP)

Already, more than 14 million fish have died since red tide developed off the Texas coast last month. With the latest kill, this year's episode may rival the state's last major red tide outbreak, which killed 22 million fish over four months in 1986. Red tide is a bloom of microscopic algae that attacks the nervous systems of fish.

2000年10月3日 · Two years ago, a massive algae bloom near Hong Kong killed up to 75 percent of the entire stock of Hong Kong's fish farms, wiping out local fishermen and triggering a political outcry in the former British territory. In Aotou, red-tide outbreaks interrupt the simple routine of daily life in this picturesque corner of southern Guangdong province.

2004年12月22日 · Of the thousands of species of algae, perhaps only a hundred are toxic. When these species occur in high concentrations, they can color the water and produce what are popularly referred to as “red tides” or “brown tides.” Scientists prefer to call these outbreaks harmful algal blooms or HABs.
