Abstract
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.
