Abstract

To promote the breeding of Heterobranchus isopterus in the peri-urban area of ​​N'Zérékoré, a study of the effect of the water quality of two fish ponds on the growth of Heterobranchus isopterus was carried out from October 15, 2019 to March 10, 2020. This study covered on two (2) E1 and E2 ponds of average depth (1.5 m) and respective surfaces of 4 ares and 11 ares.. The quantities of fish (fry) on loading are 80 for E1 and 220 for E2. The fish were fed by rice bran, oil decant, cassava leaf and potato. Pig slurry and goat droppings were used as pond fertilizers.The parameter measurements (temperature, dissolved oxygen and saturation) were performed at two depth levels (30 cm and 90 cm) of each pond and at the following times: 7:30 am, 12:30 pm and 5:30 pm. The evaluation of the growth of the 4 month old fish was based on measurements of weight, size, height and width of the fins. The results obtained showed that the parameters (temperature, dissolved oxygen and turbidity) of the two ponds E1 and E2 are relatively the same and remain favorable. the development of H. isopterus at a depth of 90 cm, but the results of the E1 pond are more recommended for a traditional fish farming. The average weights of the fish in both ponds increased from 26.5 g to 722.5 g, with an average daily increase of 3.865 g.
