Profitability of using different crude protein contents of the most commonly used commercial tilapia feed in Ghana for Nile tilapia (Oreochromis niloticus) fingerlings production

Abstract

For profitability of commercial fish farming, it is important to use economically viable fish feed. The profitability of using a commercial tilapia feed of different crude protein (CP) contents (30.0, 33.0, 38.0 and 40.0%), designated A, B, C and D respectively to produce an average of 5.0 g Nile tilapia, Oreochromis niloticus fingerlings was investigated. The declared CP contents were compared with analyzed figures. The study was carried out in hapa-in-pond system and it lasted 9 weeks. Analyzed CP contents were 30.6, 32.8, 36.5 and 38.1% for A, B, C and D respectively. Recorded final mean fingerling weights were 4.69 ± 1.92, 5.21 ± 2.11, 4.42 ± 1.94 and 5.47 ± 2.19 respectively, with B and D being significantly higher (Tukey’s HSDT, P
