초록

2008년 10월에서 2009년 9월까지 통영 주변해역에서 출현하는 별망둑 (Chaenogobius gulosus) 333개체를 대상으로 산란기, 성비, 군성숙체장, 포란수를 조사하였다. 별망둑의 체장(standard length, SL)은 2.0~12.6 cm의 범위를 보였다. 별망둑 암컷 생식소중량지수 (GSI)의 월변동을 살펴보면 2월에 연중 가장 높은 값을 보였으며, 그 이후 4월까지 감소하는 양상을 나타내었다. 간중량지수 (HSI)는 1월에 4.58로 가장 높은 값을 나타내었으며, 산란성기인 2월과 3월에 각각 3.14와 3.42로 낮은 값을 보였다. 따라서 별망둑의 산란기는 12월에서 4월로 판단되었다. 별망둑의 월별 성비는 1 : 1.06으로 암.수간 유의한 차이를 나타내지 않았다(${\chi}^2$-test, p>0.05). 별망둑 암컷의 50% 군성숙체장은 7.9 cm로 나타났으며, 9.0 cm 이상에서는 모든 개체가 성숙하였다. 포란수는 1,112~6,059개의 범위를 보였으며, 평균 3,011개를 나타내었다.

The reproductive characteristics of Chaenogobius gulosus was examined using 333 specimens collected monthly between October 2008 and September 2009 in the coastal waters of Tongyoung, Korea. Specimens ranged from 2.0 to 12.6 cm in standard length (SL). The gonadosomatic index (GSI) of females was highest in February and decreased until April, with the spawning season lasting from December to April. The monthly ratio of female to male did not significantly differ (${\chi}^2$-test, p>0.05). The size at 50% maturity for females was 7.9 cm SL. Fecundity ranged from 1,112 to 6,059 eggs, with a mean of 3,011 eggs.
