Abstract:
The aim of this study was collecting data and information of some aspects that have correlation to reproduction, the information namely lengthweight of fish, sexuality, gonad maturity, fecundity, egg diameter and water quality.
810 Lampam fishs were catched from Kapuas river, Mawan river, and Melawi lake in dry and rainy season in 2009. The result showed that there was no difference of sexual ratio between male and female Lampam from three habitats of Lampam. In dry season, the fishes had the gonad maturity from I to II, whereas in rainy season the gonad maturity from I to IV. The results of the maturity index, fecundity and egg diameter showed that Lampam has whole year reproduction time but the maximum of reproduction time was in rainy season.
