Abstract
This study aimed to evaluate the effect of different diets on the growth performance and egg-carrying ratio of rotifer. The experiment was designed as completely randomly designed, including three diets with 3 replications: NT1 (100% Nannochloropsis oculata); NT2 (50% baker’s yeast + 50% Nannochloropsis oculata); and NT3 (100% Selco S.parkle). The results showed that water quality parameters were within the suitable ranges for growing rotifer. After 8 cultured days, the highest density of rotifer was in NT3 (276 ind/mL) and was significantly different from other treatments (p < 0,05). Similarly, the highest population growth rate of rotifer was in NT3 (0.25%) on the sixth day. Also, the highest percentage of egg-carrying rotifer was also in NT3 (32.93%) and was significantly different from other treatments (p < 0,05). The results recommend that Selco S.parkle should be used to enhance the growth performance and biomass of rotifer.
