Phytoplankton (phytoplankton) is an ecological concept, is floating in the water business of small plant life, usually refers to planktonic algae phytoplankton, including Cyanophyta cyanophyta, Bacillariophyta bacillariophyta, golden algae door chrysophyta, Xanthophyta xanthophyta , Pyrrophyta pyrrophyta, Cryptomonas sp ..., freshwater phytoplankton, including cyanobacteria, hidden algae, dinoflagellates, golden algae, yellow algae diatoms, Euglena, and eight types of green algae. Algae are known around the world are about 40,000 species, of which there are 25,000 species of freshwater algae, while the Chinese have been found (including but not reported and reported have been identified) about 9000 freshwater algae species. The species composition of phytoplankton in the pond due to water salts of organic matter and nutrient content and other factors, there were significant differences between different. Plankton blooms is one of the main color decision. Darker color of phytoplankton blooms and even algae that group, said the phenomenon of floating membrane bloom. Fish pond water bloom common dominant species can be divided by 14 basic types: 1, 2 hidden bloom, bloom mouth Teng 3, Oscillatoria algae bloom or 4 seats, or seats Oscillatoria algae bloom 5, Anabaena Anabaena bloom or to be 6, 7 Microcystis bloom, pointed bloom 8, micro-algae bloom blue balls 9, 10 Volvocales bloom, bloom Prochlorococcus head 11, 12 nude bloom, bloom naked capsule 13, 14 diatom bloom, golden algae China. Usually golden algae, diatoms, hidden algae, dinoflagellate bloom almost all brown, brown and blue green algae, green algae and the algae bloom naked and colors. Generally reddish brown, green, brown, dark green water is good. Blue green, dark green, gray, green, yellow and other color as inferior mud water. The "bloom" on the fish, it has a dual nature. This water than fat, fish can provide easy digestion and absorption of the plankton species also, and this is the upside. But the long-term water quality is difficult to maintain, less experienced fish farmers is difficult to master them. When the weather changes, the algae for aquatic organisms (including their own oxygen), organic matter, a large number of oxygen and oxygen mass mortality occurs when the rapid deterioration of water quality will be black, or even smelly, affecting fish feeding, and sometimes even cause fish floating head turn lead to economic losses of dead fish pond. To control the amount of phytoplankton in ponds to control the "water bloom" to appear.

The total amount of phytoplankton carbon sequestration of terrestrial plants than the world total carbon sequestration need to make more. Despite the small phytoplankton, but (mostly) sea to expand their role. They died, the body will form a sea of "snow", together with the carbon fixed by lowering them, over many years to accumulate on the ocean floor to form a sea of oil. The temperature on Earth they have an important regulatory role. Now human pumped the oil from the seabed to use and took large amounts of carbon released into the air, carbon dioxide in the air now than any time in 2000 years to be more.
