Abstract
Tagged and untagged sea urchins, Hemicentrotus pulcherrimus (A. Agassiz) were reared for 84 days in the laboratory, Vinyl tape and trapall paper were used as tag materials. The natural mortality, mortality by predation and shedding rate of tags of the tagged groups were examined, and the results were compared with those of untagged control group. The results of Chi-square test of natural mortality between tagged and control groups were very significative, however, the comparison between the two tagged groups was insignificative. No effect of tag attachment seems to be present at the point of natural predation by starfish, and
비닐테이프와 trapall지를 사용하여 90미의 말똥성게, Hemicentrotus pulcherrimus (A. Agassiz)에 표지를 부착시켰다. 대조군으로 표지를 부착시키지 않은 말똥성게 45미와 해적으로서 별불가사리 5미를 동시에 수용하여 1984년 6월 28일부터 9월 19일까지 84일간 실험실에서 사육시켰다. 표지부착에 따른 자연사망, 별불가사리에 의한 포식율, 표지탈락율등을 표지군별로 조사하여 대조군과 비교 분석했다.
