Abstract
This study is the first to report the biometric information between the length and weight relationships (LWR) and seasonal body condition factors (K) of Sebastes zonatus Chen & Barsukov, 1976 and Thamnaconus modestus (Günther, 1877) inhabiting the waters off Ulleung-do and Dokdo. The LWRs in spring and summer, and all seasons combined were highly correlated (r2>0.959), and the regression slopes of LWRs were significantly different between the spring and summer in both species. The body conditions of the two fish were significantly higher during the spring than during the summer, reflecting their fatness in relation to spawning. The results from this study contribute to the understanding of the biology of S. zonatus and T. modestus and provide useful data for the development of conservation and management plans for these species.


본 연구는 울릉도와 독도 해역에 서식하는 띠볼락 (Sebastes zonatus Chen and Barsukov, 1976)과 말쥐치 (Thamnaconus modestus (Günther, 1877))의 체장-체중 관계 (LWR)와 계절적 비만도지수 (K) 정보를 국내 최초로 보고하였다. 두 종의 체장-체중 관계는 모든 계절에 높은 상관성을 보였으며 (r2>0.959), LWR 회귀 기울기는 두 종 모두 저수온기와 고수온기 사이에 유의하게 차이가 있었다. 두 종의 비만도지수는 저수온기에 고수온기보다 현저히 높아 산란기와 관련된 비만도 증가를 반영하였다. 본 연구의 결과는 띠볼락과 말쥐치의 생물학적 특성을 이해하고 향후 두 어종에 대한 보존 및 관리 계획 개발에 유용한 자료를 제공할 것이다.
