dc.description.abstractRiau Province has many flood plain river ecosystem, one of them is Tapung Hilir River. Tapung hilir river is one of a natural habitat for Lais Janggut fish. The purpose of this study is to investigate reproduction aspect of Lais Janggut fish from Tapung Hilir River that has not ben conducted until now. The Benefit of this research is to provide a basic information that directly effect the production of Lais Janggut fish, such as sexuality, sex ratio, gonad maturity level (TKG), gonad maturity indeks (IKG), fecundity, eggs diameter, spawning pattern and reproductive potential. The research was conducted from September 2012 to Februari 2013 in three sampling stations at Tapung Hilir River, they are Selembakan Palas, Flamboyan and Kota Garo. Total numbers of Lais Janggut Fish obtained was 431 individu, which consisted of 231 female and 200 male (sex ratio 1,15 :1). The leght and weight of male fishes was range between 15.00 to 25.80 cm and 8.40 to 56.10 g, respectively . The female fishes had legth from 16.00 to 26.50 cm and weight from 10.70 to 55.70 g. Gonad maturity level found during thius study were TKG I to TKG V. Gonad maturity indeks (IKG) of male fishes in TKG I to V was range from 0.05 to 2.75 % and female 0.03 to 12.09 %. IKG increases with TKG and decreased after spawning.en_US
