Abstract

Microalgae (i.e. single-celled algae or phytoplankton) represent the largest, yet one of the most poorly understood groups of microorganisms on Earth. As happens with plants relative to terrestrial animals, microalgae serve as the natural nutritional base and primary source of bulk nutrients in the aquatic food chain. Microalgal use by indigenous populations has occurred for centuries. Cultivated microalgae have long been integral to the hatchery production of many farmed finfish, shellfish, and other commercially important aquaculture species. By contrast, macroalgae are less widely used in aquaculture, although they do provide an important source of nutrition for certain farmed invertebrates, such as sea urchins and abalone. However, the cultivation of microalgae is only a few decades old. Commercial large-scale culture started in the early 1960’s in Japan with the culture of Chlorella by Nihon Chlorella (Taipei, Taiwan).
