- Abstract:
- A feeding test in a floating aquaponics system was conducted over the course of six weeks involving two groups of African catfish, Clarias gariepinus (BURCHELL 1822). The two groups were fed different feeds with an emphasis on the main protein source to observe the resulting differences in development dynamics. While the control group received classic feed with fishmeal, the test group’s feed contained black soldier fly meal, Hermetia illucens (LINNEÉ 1758), as a main protein source. Fish fed with the control feed showed more adequate results in the observed characteristics length, weight and condition factor but differences were only partially significant. Overall significances were only observed for weights of fish starting after five weeks of testing. It is, however, not with complete certainty to state that these discrepancies are only resulting from the different feeds, as environmental influences should also be considered.
