Algae growing in London's canals are a mix of diffrent species of green-blue and brown algae. They thrive on nutrients from ëgrey waterí from dishwashers, sinks and washing machines, that are more concentrated in the water in the summer.

Many people believed Chlorella could serve as a potential source of food and energy because its photosynthetic efficiency can, in theory, reach 8%, comparable with other highly efficient crops such as sugar cane.

Dunaliella sp. are motile, unicellular, rod to ovoid shaped (9 - 11 µm) green algae (Chlorophyceae), which are common in marine waters. The organisms are relatively simple to cultivate and do not clump or form chains.

Isochrysis is a small golden-brown flagellate commonly used in the aquaculture industry. It is high in DHA and often used to enrich zooplankton such as rotifers or artemia. Isochrysis is a primary algae found in shellfish hatcheries and in some shrimp hatcheries.

Filamentous; filaments long, solitary or coiled into clusters and fine mats (which are sometimes to macroscopic and several cm in diameter), arcuated, waved or intensely coiled, isopolar, thin, fine, 0.5-3.2 _m wide, with simple, thin but firm, usually colorless facultative sheaths opened at the apical end.

is a diatom. It is the only species in the genus Phaeodactylum. Unlike other diatoms P. tricornutum can exist in different morphotypes (fusiform, triradiate, and oval), and changes in cell shape can be stimulated by environmental conditions.

The fine structure of the thylakoids has been examined in some detail. Early reports on the fine structure of mitosis in the Cryptophyceae were with species of Rhodomonas.

General: known for producing dangerous toxins, particularly when in large numbers, called "red tides" because the cells are so abundant they make water change color. Also they can produce non-fatal or fatal amounts of toxins in predators (particularly shellfish) that may be eaten by humans.
It grows as single, motile cells visible under light microscope up to concentrations over one million cells per milliliter. It can be grown as a foodstock in aquaculture, being amenable to species such as rotifers of the genus Brachionus.
