Sexual maturity was reached in as little as six days at a carapace length of 6.5 mm. A biomass of 2.0 g, at carapace length of 25 mm was achieved in two months. Males and females occurred in similar numbers and matin

Comparisons were made with other pools with phyllopods in Africa. The data reveal the broad tolerance to variation and ext
