Biological Effect with Remove the Attached Organisms of Haliotis discus hannai
북방전복 Haliotis discus hannai의 부착생물 제거에 따른 생물학적 영향
Abstract
In this study, data on the types and density of abalone attached organisms were provided in marine net cage of the southern coast. In addition, the effect of the removal of attached organisms was evaluated. In marine net cage, oysters, bryozoa, and barnacles were dominated among the attached organisms, and their average area ratio was about 57.5%. The growth rate and hepatopancreas condition were better in removal group of attached organisms than control group. Therefore, it is judged that the removal of attached organisms from abalone is necessary for the growth of individuals and improvement of value.
본 연구에서는 한국 남해안의 해상가두리에서 북방전복 Haliotis discus hannai 부착생물의 종류 와 밀도에 관한 자료의 축적과 부착생물 제거에 따른 영향을 평가하고자 하였다. 해상가두리에 서 북방전복의 부착생물은 굴, 태형동물, 따개비가 우점하였으며, 이들의 평균 부착생물 면적비 는 약 57.5%였다. 성장률과 간췌장의 건강도는 대조구에 비해 부착생물 제거구에서 좋은 결과 를 보였다. 따라서 전복의 부착생물 제거는 개체의 성장과 출하 시 상품성 향상을 위해 필요한 것으로 판단된다.
