dc.description.abstract This study presents data on spawning season, weight-length relationships (WLRs) and condition factor of Gadus chalcogrammus inhabiting the middle East Sea, Korea. Monthly changes in the gonadosomatic index (GSI) revealed that the spawning period was from December to March. Overall value of the exponent b, estimated by nonlinear least squares from weight and length data was 2.806, ranging from 2.778 for female fishes to 2.985 for immature group. The b values were similar between spawning and non-spawning, and between female and male fishes, but it was significantly higher for immature than mature fishes. The condition factors were significantly higher for immature than mature groups, and during non-spawning than spawning periods, but it was not significant between male and female fishes. 본 연구는 동해 중부 연안에 출현하는 명태 (Gadus chalcogrammus)의 산란기, 체장-체중 관계 (weightlength relationships, WLRs), 비만도 (condition factor)를 조사하였다. 생식소숙도지수 (gonadosomatic index, GSI))의 월변화를 통하여 추정한 명태의 산란기는 12월에서 3월이었다. 전반적인 체장-체중 관계식의 지수값 b는 2.806이었고, 2.778 (암컷)에서 2.980 (미성숙 그룹)의 범위를 나타냈다. b값은 암수 사이에서 유사하였으나, 미성숙 그룹과 비산란기 동안 성숙 그룹 또는 산란기 보다 유의하게 높은 값을 나타냈다. 비만도는 미성숙 그룹에서 성숙 그룹보다 유의하게 높았으나, 산란기와 비산란기, 암컷과 수컷 사이에서는 유의한 차이가 없었다. -
