“…It has been agreed in several literature that Chlorella alone and it's combination with yeast gives better result for population growth of B. calyciflorus (Sarma et al, 2001;Arimoro and Ofojekwu, 2004;Asraf et al, 2010;Pena-Aguado et al, 2005). In this study comparatively higher production of rotifer from the diet in combination of yeast (T 2 ) than powder Chlorella vulgaris (T 3 ) with fresh Chlorella vulgaris is probably an indicator that yeast is more effective than powder Chlorella as combined food with fresh Chlorella.…”

“…Seeds of Brachionus calyciflorus were cultured in four plastic jars of 5 liter capacity for one month, with continuous aeration for 24 hrs by air pumps. To achieve pure culture of the rotifer 'Basudine' was applied at the rate of 1.5 mg l -1 (Arimoro and Ofojekwu, 2004). Fresh cultured Chlorella vulgaris was used as food.…”

A study was conducted to evaluate the effect of yeast Saccharomyces cerevisiae and algae Chlorella vulgaris on the production of rotifer Brachionus calyciflorus. The Brachionus calyciflorus were cultured using four different types of diets: fresh Chlorella vulgaris (T1), yeast with fresh Chlorella vulgaris (T2), powder Chlorella vulgaris with fresh Chlorella vulgaris (T3) and yeast with powder Chlorella vulgaris (T4). We compared these diets to find out their potentiality on the population growth of Brachionus calyciflorus. The rotifers were cultured under natural environmental condition with continuous artificial aeration. Initial density of Brachionus calyciflorus were 8 individuals ml-1 (ind. ml-1). Water temperature and pH were measured during the culture period. Among the four different diets the fresh Chlorella vulgaris (T1) and its yeast combination (T2) gave satisfactory production of rotifer 73±9 and 67±8 ind. ml-1, respectively. However, processing of fresh Chlorella vulgaris to produce powder form declined the production ability of rotifer. The diet sample T3 and T4 containing powdered Chlorella vulgaris produced 48±9 and 25±6 ind. ml-1, respectively. So, the diet in combination of yeast and fresh Chlorella is suggested for the sustainable production of the rotifer Brachionus calyciflorus.

“…The rotifers produced toxins in the medium, thereby decreasing the rotifer fecundity or survival after the eighth day. Though Ozdmire and Ciltas (2010) observed their highest peak of rotifer population growth on the fifth day (5), Arimoro and Ofojekwu (2004) attained peak population density after 10days of culture. Although food types, food concentrations and feeding level (interval) attained highest population growth at day 8, Chlorella sp.…”

In this research, mass production of freshwater rotifer, Branchionus calyciflorus, for aquaculture in southeastern Nigeria, using different food types (Chlorella sp., Spirulina sp and Baker's yeast) was investigated. Rotifer stock culture was prepared using Nitrogen phosphorus Potassium, (NPK) + urea (50 : 2.5 g) and chicken droppings (25 g) with freshly grown alga. Different food concentrations (150, 300, 650 and 1000 mg/ml) and feeding intervals (2x and 3x per day) were used to grow B. calyciflorus in a Batch culture method. The highest population growth was attained with 650 mg/ml of Chlorella sp. (213.81±9.94 individuals/ml), followed by Baker's yeast (196.67±8.18 individuals/ml) and 300 mg/ml of Spirulina sp. (151.90±7.98 individuals/ml). The least population growth of B. calyciflorus was recorded with 150 mg/ml concentration of Chlorella sp. and Spirulina sp. (81.43±6.19 and 75.71±5.12 individuals/ml, respectively), and 1000 mg/ml of Baker's yeast (from local market) (65.24 ±3.86 individuals/ml). The peak population growth was attained on day 8 of experiment (p < 0.05). This study indicated that both the quantity and quality of food type have significant role on mass production of rotifer for aquaculture.

“…Resting eggs are also ideal for aquaculture because of their easy storage, transport and rapid hatching. These characteristics make rotifer hatching from resting eggs very attractive as inocula for mass cultures are used directly as food for commercial hatcheries [16].…”

Rotifers are the most important live food organisms for use as starter food in aquaculture. The population growth and resting egg production dynamics of Brachionus calyciflorus sibling species BNA13 from lake Baixiang and BNB3 from lake Kongque, in Xishuangbanna city, Yunnan, China at four temperatures (16, 20, 24, and 28°C) and four algal (Scenedesmus obliquus) densities (0.5, 1.0, 2.0, and 4.0 9 10 6 cells/ml) were studied. The results showed different responses with rotifer sibling species. Sibling species, temperature, algal density and their interactions significantly affected the maximum population density, population growth rate and resting egg production except that both the interactions of temperature and algal density and the interaction of sibling species and temperature as well as algal density did not significantly affect maximum population density. Regardless of the effects of temperature and algal density, maximum population density, population growth rate and resting egg production of the B. calyciflorus sibling species BNA13 were greater than those of BNB3, suggesting that B. calyciflorus sibling species BNA13 was more suitable than BNB3 for fish larviculture. The maximum population density and resting egg production of sibling species BNA13 were the highest at the combination of 20°C and 4.0 9 10 6 cells/ml algal density and 28°C and 4.0 9 10 6 cells/ml algal density, respectively, indicating that the two combinations of temperature and algal density represented the optimum conditions of mass culture and resting egg production of B. calyciflorus sibling species BNA13 for fish larviculture respectively.
