Cyanobacteria (blue-green algae) bloom on Lake Erie (United States) in 2009. These kinds of algae can cause harmful algal bloom. A harmful algal bloom (HAB), or excessive algae growth, is an algal bloom that causes negative impacts to other organisms by production of natural algae-produced toxins, water deoxygenation, mechanical damage to other organisms, or by other means.
These two strains are found to have similar niches in coastal areas. A surplus of Dinoflagellates in the night time creates a blue-green glow, however, in the day, it presents as a red brown color which names algal blooms, Red Tides. Dinoflagellates have been reported to be the cause of seafood poisoning from the neurotoxins. [41]
Karenia brevis is the causative agent of red tide, which occurs when the organism multiplies to higher than normal concentrations. During these events the water can take on a reddish or pinkish coloration, giving these explosions in the K. brevis population the name of Florida Red Tide.
A red tide forecast from the University of South Florida shows the likelihood of the harmful algal bloom’s presence around Tampa Bay and Southwest Florida over the coming days.
About red tide: It can cause fish kills, seafood poisoning and breathing difficulties. If ingested from the water, it can cause digestive problems
Red tide blooms produce toxic chemicals that can affect both marine organisms and humans. The Florida red tide organism, known as K. brevis, produces brevetoxins that can affect the central ...
A Red tide is a discoloration of the sea water by pigmented cells like Gonyaulax spp., some of which may produce toxins. Gonyaulax spinifera has been connected to the production of yessotoxins (YTXs), a group of structurally related polyether toxins, which can accumulate in shellfish. [8]
