Rotifers are multicellular animals with body cavities that are partially lined by mesoderm. These organisms are valuable live food for larval fish and crustacean culture. Several characteristics of rotifers, including their nutritional quality, body size and relatively slow motility have contributed to their usefulness as good prey for active larvae (Snell and Carrillo, 1984). In general, rotifers have both nutrient content and a high rate of daily production (Lubzens, 1987). Rotifer transmits adequate supplies of micro and macronutrients, vitamin and even antibodies to the fish larvae (Gatesoupe, 1982). The level of polyunsaturated ω-3 fatty acids in rotifer is believed to affect both survival and growth rate of fish larvae (Koven et al., 1990). Rotifer forms an excellent initial food because of its appropriate size (130-320 μm), planktonic nature, rapid production rate, suitability for mass culture under controlled conditions, ability to grow and reproduce in high density cultures and the possibility of artificially manipulating its nutritional qualities along with the euryhaline nature (Dhert et al., 2001).
