| Sumario: | The study was conducted at Kegati Aquaculture Center (KMFRI) for 12 weeks to evaluate the effect of water quality parameters on the growth and survival rates of Oreochromis jipe and Oreochromis niloticus. The fingerlings (n = 270), were stocked in triplicates in 9m2 raised ponds arranged in double series and fed on a 30% CP ration twice a day at 10% total bodyweight. Water quality parameters were measured daily using the YSI multi-parameter meter. Fish total length and bodyweight was determined biweekly using a measuring board and a digital weighing balance, respectively, and survivals were determined from the initial and final counts of fingerlings. Data were analyzed with an unpaired sample t-test using R-software and statistical significance was considered at p < 0.05. Temperature, total dissolved solids (TDS), and salinity showed no significant differences, whereas the pH and dissolved oxygen (DO) levels were significantly different (p < 0.05) between the O. jipe and O. niloticus. Furthermore, O. jipe attained a lower final mean weight (12.16 ± 0.34 g) compared to O. niloticus (29.79 ± 0.91 g). The study recommends a further study be conducted in a controlled culture environment to establish optimal conditions for O. jipe culture. |
