| Summary: | The culture of microalgae is of fundamental importance to commercial hatcheries rearing
marine molluscs, since they are currently the only suitable food source. Molluscs, unlike
fish and crustaceans, are fed microalgae directly. Consequently, mollusc development is
closely related to the quantity and quality of phytoplankton produced. Microalgal cultures
are necessary because the concentration of natural phytoplankton in the seawater used in
the hatchery is generally insufficient for optimum growth of the high densities of larvae and
juveniles reared. Moreover, to avoid bacterial diseases, the seawater used for rearing is
purified, usually by fine filtration (0.2–1.0 m) and/or ultraviolet (UV) treatment (Robert &
Gérard 1999). This eliminates almost all of the natural phytoplankton, which must then be
replaced by dense artificial cultures. |
