Red Tide refers to a phenomenon known as an algal bloom, an event in which estuarine, marine, or fresh water algae accumulate rapidly in the water column, or “bloom”. These algae, more specifically phytoplankton, are microscopic, single-celled protists, plant-like organisms that can form dense, visible patches near the water’s surface. Certain species of phytoplankton contain photosynthetic pigments that vary in color from green to brown to red, and when the algae are present in high concentrations, the water appears to be discolored or murky, varying in color from white to almost black, normally being red or brown.

Tips:

 ·Increase oxygen partially in the affected area (only effective to red tide caused by phytoplankton).
 ·Adopt effective measures to prevent further spread of the red tide, such as the quarantine of partially over-fertilized aquatic breeding farms.

Suggestions:

 ·Reduce as much as possible the energy level of ocean ecological system and the input of detrimental man-made substance. Gradually decrease the amount of industrial waste from enterprises along the coast and on the ocean and the drainage sewage water from the cities.
 ·Reduce or avoid man-made pollution caused by over aquatic farming or over fishing along the coast line.
