Abstract:
In an effort to address under- and malnourishment in Haiti, feed formulations for Nile tilapia (Oreochromis niloticus) were developed using regionally available and sustainable foodstuffs that are not commonly eaten by people, to support the development of aquaculture-based protein in Haiti. Moringa leaves (Moringa oleifera), spent brewer’s grain (Hordeum vulgare), wet and dried spent brewer’s yeast (Saccharomy cescerevisiae), cassava root (Manihot esculenta), breadfruit (Arthocarpus altilis) and blood meal were examined as ingredients in six feed formulations developed using linear programming. Two experiments with six experimental isonitrogenous diets were conducted under controlled laboratory conditions to examine fish growth, and feed palatability, digestibility and pellet stability. Results from Experiment 1 indicated that tilapia fingerlings had better growth (120% weight gain), feed conversion, efficiency and palatability fed with Diet2 compared with Diet 1 (58% weight gain) after 69 days. A second experiment conducted with the samecohort of fish discerned formulation variables associated with differences observedbetween diets in Experiment 1. New diet formulations in Experiment 2, however,failed to provide positive growth, improved palatability or feed efficiencyafter 24 days. Results indicated that breadfruit and cassava are acceptablebinders for other proteinaceous ingredients, but >5% brewer’s yeast in dietformulations negatively impacts feed palatability.(5% brewer’s yeast in diet formulations negatively impacts feed palatability. Further, feed palatability may vary for fish of different sizes. Ingredients examined in this study provided important utility in formulating sustainable feeds that, along with phytoplankton stimulation, should augment community-based tilapia culture in Haiti.
