We have developed a polyculture container which is preferable for rearing of abalones and sea cucumbers in East Sea. To test the rearing capacity of the polyculture container, 50, 75 and 100 sea cucumbers ranging from the body length of 7-9 cm were cultured in three containers including 500 abalones with the shell length of about 5 cm, respectively. It was revealed that preferable density for sea cucumbers was 52-72 individuals in the polyculture container. Glutamate oxaloacetate transaminase and glutamate pyruvate transaminase were analyzed with Reflotron kit to investigate the health degree of abalones in two polyculture containers including 300 and 500 abalones with the shell length of about 5 cm. Glutamate oxaloacetate transaminase has been an important tool to know myocardial infarction, disease of liver, and destruction of muscle. Next experiment was conducted to determine the effects on growth of abalones and sea cucumbers in polyculture container. Experimental findings, RNA/DHA ratio, DNA and RNA contents (ug/mg) were not significantly different among all groups. The results imply that the method of polyculture can be rearing with sea cucumber without growth retardation of abalone. Production ability between polyculture container and the container used in south sea were carried out using suspended culture method during 8months. It was revealed that abalones and sea cucumbers are faster growing in polyculture container than in container used in south sea. Therefore, polyculture container is considered more appropriate for the abalones and sea cucumbers culture in East Sea.
