초록

남극 연안에 우점하는 남극암치아목과, 암치아목속 어류 두 종 (Notothenia coriiceps와 Notothenia rossii)의 전장과 무게의 관계를 조사하였다. 어류는 2017년 1월에 남극 킹조지섬에 위치한 세종과학기지 연안에서 낚시로 채집되었다. 총 30마리가 채집된 N. coriiceps의 평균 전장은 266.0 mm였고, 7마리가 채집된 N. rossii의 평균전장은 275.4 mm이었다. 평균 무게의 경우 N. coriiceps는 283.1 g이었고, N. rossii는 290 g이었다. 전장과 무게의 관계를 조사한 결과, 두 종 모두 양의 상대성장 값(b>3)을 보였다. 본 조사에서 얻은 남극 연안에 우점하는 두 종의 크기 자료는 남극 해양생물의 환경적응 기작과 생물학적 대사과정을 이해하기 위한 관련 생리 연구를 수행하는데 있어서, 좋은 기초자료로 활용될 수 있을 것으로 기대된다.

Length and weight relationship (LWR) for dominant Antarctic fishes was determined in two species of the family Nototheniidae; black rockcod (Notothenia coriiceps) and marbled rockcod (Notothenia rossii). Samples were caught in the offshore sea around King Sejong station located on King George Island, Antarctica in January, 2017. A total of 30 N. coriiceps and 7 N. rossii were caught by fishing rod and hook. Average total length was 266.0 mm for N. coriiceps and 275.4 mm for N. rossii. Average total weight was 283.1g for N. coriiceps and 290 g for N. rossii. In terms of LWR and b value, the results showed that both two species had positive allometries (b>3) in good health. This size information of two dominant Antarctic fishes would be useful for future physiological studies to understand of adaptation mechanism and biological pathway of Antarctic marine organisms.
