Symptoms usually disappear within 24 hours once the exposure is discontinued. In an area known as Long Neck, a fish kill was discovered by a gentleman of Winding Creek Village on Monday, Jan. 15 2001. Until recently, fish kills have been associated with warm brackish water, usually occurring after heavy rainfall and associated run off into streams, rivers, bays, and eventually the ocean. Numerous types of organisms survive and proliferate in these conditions. Levels of toxic dinoflagellates are currently being analyzed.
Algae blooms Are responsible for oxygen deprivation killing of marine life.
The filament remained detectable in satellite images for three weeks. Notice the similarities of back bays and barrier island to Ocean City Maryland. Many organisms, from fish to microorganisms, are known to be able to spread in ballast water, and are transferred between regions, countries and continents. Toxic species of dinoflagellates may be eaten by shellfish and result in food poisoning and human fatalities. One example is the outbreak of a toxic algal species Chattonella in Sydney Harbour towards the end of 1996.
