초록

동해안 일대의 양식자원 증식과 어업인의 소득증대를 위해 남해안 일대에서 주를 이루고 있는 전복양식을 동해안 일대로 넓히기 위해서 수심이 깊고 파고가 높은 동해안 지역에 맞는 전복과 해삼 복합사육기를 개발하고 복합사육기의 효과를 알아보고자 양식 생산력을 조사하였다. 전복해삼복합사육기에 각장 5 cm 전복 500마리와 7-9 cm 해삼을 50, 75, 100마리로 각각 넣어 실험한 결과 해삼 적정수용능력은 13-18마리/$m^2$로서 사육기당 52-72마리가 적절하였다. 수용량에 따른 생화학적 건강도를 조사하기 위해서 복합사육기에 각장 5 cm 전복 300마리와 500마리를 각기 달리 수용하고, Reflotron kit를 이용하여 GOT (glutamate oxaloacetate transaminase) 와 GPT (glutamate pyruvate transaminase) 를 조사하였으며, 전복과 해삼을 함께 사육하여 RNA/DHA ratio와 DNA 및 RNA contents (ug/mg) 를 조사한 결과, 전복 단독구와 복합사육구간에 유의적인 차이가 없어 (P > 0.05) 전복과 해삼을 함께 양성하더라도 해삼이 전복 성장에 영향을 미치지 않는 것으로 나타났다. 또한, 자체 개발한 전복해삼 복합사육기와 남해안에서 주로 사용되고 있는 전복 사육기의 생산능력을 비교하기 위해서 수하식으로 8개월 동안 실험한 결과, 자체 개발한 복합사육기에서 양식한 전복과 해삼이 성장이 빨라 전복해삼복합사육기가 동해안 일대의 양식사업에 적합한 것으로 나타났다.

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.
