| Comments: | Mature females are present from July-November (Ref. 84543). Insemination is carried out during the dry season where encounter between the sexes are most probable due to reduced water volume. Spawning occurs during the rainy season where presence of food is optimized and predation is reduced to ensure offspring survival (Ref. 84543). | |||||||||||
