Growth Performance of Nile Tilapia (Oreochromis Niloticus) Fingerlings Fed on Soybean (Glycine Max) Compared to Dagaa (Rastreneobola Argentea) Meal with Diet Supplement of Maize Bran.

A study was conducted at Maseno University to evaluate the growth performance of Nile tilapia (Oreochromis niloticus) fingerlings fed on soybean (Glycine max) and dagaa (Rastrineobola argentea) meals separately. The experimental feeds used were Glycine max and Rastrineobola argentea. A total of 160 fingerlings were used during this experiment. The fingerlings were fed at 5% of their mean body weight on daily basis for 5 weeks and the feed amount adjusted after every sapling in relation to body weight. There were 2 replicates for each feed therefore 4 hapas were used hence 40 fingerlings for each hapa net. The concrete pond used was drained and left to dry for 4 days to kill any available parasites before filling with water. After filling the pond with water, it was fertilized using DAP to promote the growth of phytoplankton in the water before stocking with the fingerlings. Sampling was done weekly to determine SGR and FCR of the fingerlings from each hapa. Statistical analysis was done using SPSS v. 16.02. Although there was observable difference, statistically there was no significant difference between the two treatments. In weight p=0.73 (p>0.05) and length p=0.61 (p>0.05). The average temperature during the project period was 24.4°C+/- 0.33 while the pH was 8.87+/- 0.28.
