Abstract
The current study was conducted to evaluate the effect of supplementing
fish and gluten meals with chitosan and chitosan nanoparticles on the Nile
tilapia growth performance, feed utilization, fatty acids profile and liver
histology. The experimental design was completely randomized with a 2 x 3
factorial design; two protein sources; fish and gluten meals, and three forms
of chitosan (zero-chitosan, chitosan and chitosan nanoparticles). A total
number of 270 O. niloticus fingerlings were randomly distributed among 18
tanks (55 liters water capacity). The experiment lasted for 82 days. Results
indicated that the growth performance parameters and protein efficiency
ratio of fish fed gluten meal-based diets were improved by the addition of
chitosan nanoparticles. Additionally, it was found that supplementation of
gluten meal-based diet with chitosan nanoparticles increased the total
omega-3 level, while decreased the omega-6/omega-3 ratio. Moreover,
supplementation of gluten meal-based diets with chitosan nanoparticles
improved the histological architecture of the liver and reduced fish
mortality. Consequently, it is recommended to use chitosan nanoparticles as
feed additives to gluten meal-based diets at a level of 0.5%.
