What is Red tide??

Answer 1

Red tide is a naturally-occurring, higher-than-normal concentration of the microscopic algae Karenia brevis (formerly Gymnodinium breve).

This organism produces a toxin that affects the central nervous system of fish so that they are paralyzed and cannot breathe. As a result, red tide blooms often result in dead fish washing up on Gulf beaches. When red tide algae reproduce in dense concentrations or "blooms," they are visible as discolored patches of ocean water, often reddish in color.

Answer 2

A red tide is an unusually large "bloom" of some species of algae (not always actually red in color) in a relatively concentrated area. It is usually caused when a cold water that is high in nutrients rises to the top in a upwelling, causing the population of of these species to increase rapidly and dramatically. Red tides can cause a severe depletion of oxygen in the water, killing off other species of marine life; some species also produce toxins which are poisonous to human beings, creating a scenario where shellfish from the affected area cannot be safely consumed.

Answer 3

Red tide is estuarine or marine algal bloom. Red tide is caused by species of dinoflagellates, often present in sufficient numbers (thousands or millions of cells per milliliter) to turn the water red or brown.
effects on humans..
. These compounds move from nerve, to muscle, to brain, to sinus, to eye, to GI tract, to skin and joint tissues. These symptom just don't go away but cause chronic illness. Even just breathing the air around the infected areas can cause a contamination. There is a time period before and after an algae bloom or fish kill, approximately two weeks, called recreational and residential contamination. This time period would be in the absence of "fish kills" warnings randomly being designated by state authorities....
First warnings of contamination......
multiple symptoms. Fatigue, weakness, muscle aches, cramps, unusual pains like and ice pick going in ones back or neck, muscle cramps. Also memory loss, especially short term assimilation of data, and sensitivity to bright light, like a new sensitivity to bright lights at night driving would bother you when it hadn't before. Respiratory illness, an increase irritation or chronic respiratory problems that don't go away, even after asthma

Answer 4

a red tide is called when it occurs when either natural or human factors cause a rapid increase in the production of one celled organisms (dinoflagellates) which ordinarily grow in water rich in nitrogen and phosphorous. these destructive red tides, often resulting in what is known as paralytic shellfish poisoning, have occurred since biblical times but are becomimg much more prevalent today. sewage effluent and runoff from farms and lawns contain nitrogen and phosphorous. the dinoflagellates consume the nitrogen and phosphorous, when added to the oceans, and then reproduce or bloom profusely. they spread across water like a carpet, absorbing oxygen and shutting off sunlight from plants. when these organisms die and decay, they absorb more oxygen, literally suffocating marine life...

Answer 5

It's caused by Algae. Check Weblink for info.

Answer 6

A bacteria in salt (ocean) water that is absorbed by shellfish, this bacteria is poisonous to humans

Answer 7

Dead bacteria. I live by the beach and from what I know, it is a normal part of natrure, and it smells like sewage.

Oh crap, what have I been swimming in?????

I think it refers to a woman's period.
