Nutritional effect of three microalgae and one cyanobacteria on the culture of the rotifer Brachionus plicatilis Müller: 1786
Three microalgae and one dehydrated cyanobacteria were tested to determine the best concentration and the best food for the culture of a local strain of the rotifer Brachionus plicatilis type L. The observations were: density of rotifers, fecundity and biochemical analyses (carbohydrates, proteins...

| Sumario: | Three microalgae and one dehydrated cyanobacteria were tested to determine the best concentration and the best food for the culture of a local strain of the rotifer Brachionus plicatilis type L. The observations were: density of rotifers, fecundity and biochemical analyses (carbohydrates, proteins and total lipids). Of the food tested, Nannochloris sp., with a density of 25 × 106 cells.ml–1, produced the best yields and fecundities in the rotifer culture, followed by Nannochloropsis sp. at 25 x 106 cells.ml–1, Chlorella sp. at 35 × 106 cells. ml–1 and, finally, dried Spirulina sp. with densities of 0.67 and 0.9 g per 1.5-l volume (fecundity and density, respectively). According to the biochemical analyses, the best food was Chiarella sp., followed by Nannochloropsis sp., Nannochloris sp. and dried Spirulina sp. It is concluded that Nannochloropsis sp. and Nannochloris sp., at a concentration of 25 × 106 cells. ml–1, are suitable feeds for the culture of B. plicatilis. |
