This study was undertaken to determine the suitable habitat for the rearing of one of the most prized edible frogs in Africa, particularly in Côte d'Ivoire. For this purpose, three environments were selected in ponds and concrete basins. The design of these environments took into account the semi-aquatic and semi-terrestrial lifestyle of the frogs. We then placed wild male and female specimens of the species studied in these habitats in order to test and improve them. Thus, regular measurements

In the 1.8 m 3 concrete basins, the average survival rate was 13.41% after 30 days, whereas it was 75.00% and 83.33% after 60 days in the 3 m 3 concrete basins and 13.5 m 3 pond enclosures respectively. The average pH of the aquatic environments was 9.99 in the 1.8 m 3 basins, 8.87 in the 3 m 3 basins and 6.76 in the enclosures. The 3m 3 concrete basins and mesh enclosures maintained milder temperatures (29.83 °C to 30.52 °C), with high air temperatures. This study has shown that the improved environments of the 3m 3 basins and mesh enclosures are suitable for rearing adult Hoplobatrachus occipitalis frogs.
