The present study investigated survival and growth of the abalone, Haliotis discus hannai and sea cucumber, Stichopus japonicus co-cultured and supplied with abalone formula feed (AFF) and dry sea tangle (DST) in indoor tank. During the experimental period from April 20 to July 15 in 2011, we used abalone with shell length of 28.54 ± 1.23 mm and total weight of 2.92 ± 0.26 g. The sea cucumber used in the experiment weighed 3.0 ± 0.2 g in wet weight. For the experiment, 3 types of feeds

During the experiment, survival of abalone reached over 97.0% and 87.0% for sea cucumber in three experimental tanks. Survival of the abalone was found to be higher in DST group, while it was lower among sea cucumber, although the survival was not significantly different among three experimental group. Growth of abalone fed with AFF was significantly higher, while the growth rate of sea cucumber was highest in the tank fed with AFF+DST mixed diet (P < 0.05).
