The nutritional composition such as protein, carbohydrates and lipid of Betta
splendens when submitted to different feeds are evaluated. The three different feeds
were used are Chlorella vulgaris pellet, commercial pellet and mixed (50 % Chlorella
vulgaris and 50 % commercial feed). This study tested that variables of feeds would
have significant effects on the Betta splendens by placing the fish with 30 small
aquariums and each 10 aquariums were feeds different feed. The water quality
parameters such as pH, temperature, and dissolved oxygen were analyzed everyday
using YSI Multiparameter. Results showed that the mixed diets were dominant feed
which is resulted in higher nutritional composition of protein (26.09% dry weight),
carbohydrates (29.19% dry weight) and lipid (5.095% dry weight). Betta splendens
fed with mixed diet also showed significantly higher nutritional composition of protein
(28.87% dry weight), carbohydrates (22.84% dry weight) and lipid (17.05% dry
weight) compared to others. This shows that mixed diet are the best feed for Betta
splendens compared to others.
