Description Marine ornamental seed production is a lucrative business, and also an environmentally sound alternative to
harvesting them from their reef habitat. Unfortunately, the practice is still greatly lagging because of the biological and
economic constraints associated with culturing most marine species. Many species have not been cultured because
of their complex reproductive biology; and non availability of suitable breeding and larval rearing technology. Marine
fish larvae are, by in large, very fragile organisms and have specific nutritional and environmental requirements that
change frequently and are often difficult to provide. This makes larval rearing the most critical, time consuming and
complicated phase of the culture process. The length of the larval phase and the capabilities of larvae at hatching
varies depending upon the species. Obviously, species that have well developed first feeding larvae with a short larval
phase are better cultured candidate species. Clownfishes and dottyback larvae can swim and feed at hatching and
complete their larval phase in about 15 days and 30 days, respectively.
