AB - In this study, we envisage that developing
suitable feed for fish hatcheries from indigenous
feedstuffs reduces production costs and creates
income. Whereas such feedstuffs in Uganda are suitable
for starter feed, they fail to attract Clarias gariepinus
(C. gariepinus) larvae to feed. Knowledge gaps in
feedstuffs properties and presentation limit intake and
consequently stunted larval growth. This study evaluated
indigenous fish baits and specifically assessed their
potential to induce feeding behavior in C. gariepinus
larvae, determined amino acid profiles of selected baits
and selected the most suitable for further evaluation of
feeding attraction to larvae. Methods comprised larvae
behavioral feeding trials and profiling of amino acids in
indigenous fishing baits including Zingiber officinale
(ginger), Curcuma longa (turmeric), Abelmoschus
esculentus (okra), Hibiscus sabdariffa (malakwang),
Lumbricus terrestris (earthworms), Biomphalaria
choanompala (lake-snails) and Chlorella species
(algae). Data were subjected to hierarchical cluster
analysis and scree tests. Results showed significant
differences in attraction among baits p = 0.001 at
95% confidence level, preference for ginger based
rations followed by earthworms, okra and
malakwang rations. A cluster comprising ginger,
earthworms and control was significantly different
(R2 = 0.9683) from algae, snail and turmeric and
control cluster. Comparison of amino acids
concentration in ginger and earthworm gave
p>0.05, for proline, aspartic acid, leucine, valine
and glutamic acid. Therefore, behavioral and amino acid
properties of ginger and earthworms showed prospects
for inclusion in local starter rations for C. gariepinus.
