Description Marine algae are single-celled plants and like all plants, contain chlorophyll, which traps the energy from
light and uses it to convert nutrients and carbon dioxide dissolved in the sea water into organic matter. Microalgae
are the primary producers of the sea. Among microalgae, flagellate and diatom species, are primary producers
at the base of the marine food chain. They are cultured in hatcheries in suitably treated seawater enriched with
nutrients, which include nitrates, phosphates, essential trace elements, vitamins and carbon dioxide. Synthetic
seawater may be used but it is expensive except for small laboratory scale cultures. The culture microalgae
arise because the natural phytoplankton content of seawater is insufficient to support growth of high densities
of larvae and juveniles reared. Particularly in the hatchery, the water treatments will remove almost all of the
natural phytoplankton which then needs to be replaced from cultures of preferred, high food value species. In
this context, few of the naturally occurring algae of good food value are amenable to artificial culture.
