낙동강 유곡천에 서식하는 수수미꾸리 Kichulchoia multifasciata(Pisces: Cobitidae)의 산란시기와 산란특성 = Spawning Period and Spawning Characteristics of Kichulchoia multifasciata (Pisces: Cobitidae) in the Yugokcheon (stream) of Nakdonggang (river) from Korea

다국어 초록 (Multilingual Abstract)

Spawning period and spawning characteristics of Kichulchoia multifasciata (Pisces: Cobitidae) inhabiting the Yugokcheon (stream) of Nakdonggang (river) were investigated in the area of Segangyo (bridge), Yugok-myeon, Uiryeng-gun, Gyeongsannam-do, Korea from November 2008 to October 2009. The total length of population indicated that 45~55 mm group is one year old, 55~75 mm group is two years old and longer than 75 mm is regarded over three years old in males and 40~55 mm group is one year old, 55~75 mm group is two years old, 75~95 mm group is three years old and longer than 95 mm is considered over four years old in females (January 2009). It has predicted that the spawning period is from May to June (water temperature in the range 21.0~26.6°C). Sexually matured individuals appeared over the two years old. The number of eggs in the ovaries was 202~747 (491±154.0).
