The efficacy of three different algae (Ascophyllum nodosum, Porphyra yezoensis, and Ulva pertusa) were compared in fingerling red sea bream Pagrus major. Oregonmoist diet containing 5% of algae meal were fed for 41 days and the effects weremonitored in terms of growth, feed efficiency, and body composition.
Feeding algae commonly elevated body weight grain, and tended to increase feed efficiency and muscle protein deposition. Algae-fed groups were higher in liver glycogen andtriglyceride accumulation in muscle. Feeding Porphyra showed the most pronouncedeffects on growth and energy accumulation, followed by Ascophyllum and Ulva. Theresults suggest the practical efficacy of using algae as a feed additive for theeffective use of nutrients in cultured fish.
