2011년 4월 20일부터 7월 15일까지 전복배합사료와 건다시마를 먹이원으로 한 북방전복과 해삼의 실내 복합사육에서 생존율과 성장에 어떠한 영향을 받는지 관찰하였다. 실험에 사용된 북방전복의 크기는 각장 <TEX>$28.54{\pm}1.23mm$</TEX>, 전중량 <TEX>$2.92{\pm}0.26g$</TEX> 이었고, 해삼은 습중량 <TEX>$3.0{\pm}0.2g$</TEX> 이었다. 먹이는 전복배합사료 실험구, 건다시마 실험구 및 전복배합사료와 건다시마 혼합 실험구로 설정하였다. 북방전복과 해삼의 생존율은 모든 실험구에서 각각 97.0%, 87.0% 이상을 보였다. 북방전복의 생존율은 건다시마 실험구에서 가장 높은 반면 해삼은 가장 낮았지만 유의적인 차이는 보이지 않았다. 성장은 북방전복의 경우 전복배합사료 실험구에서, 해삼의 경우 전복배합사료와 건다시마를 동시에 공급한 실험구에서 가장 빨랐다.
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 including AFF, DST and AFF-DST mixed (1:1) group were supplied to abalone and sea cucumber. During the experiment, survival of abalone reached over 97.0% and 87.0% for sea cucmber 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 rae of sea cucumber was highest in the tank fed with AFF+DST mixed diet (P < 0.05).
