Özet
The quantitative determination of aerobic bacterial flora in rotifer (Brachionus plicatilis O.F. Müller,1758) in large scale rotifer cultures.In this study, depending on the nutritional regime, quantitative analysis of aerobic bacterial flora in both culture media and rotifers grown in large scale tanks (2700 L.) was carried out.M65 agar, TCBS-Cholera Medium Agar (Oxoid) and Pseudomonas-CFC-Agar (Oxoid) were used for counting of total bacteria, Vibrio spp.and Pseudomonas spp.respectively.Protein selco, algae (Isochrysis galbana; Tahitian strain, Tetraselmis suecica; Nannochloropsis oculata; Droop 1955), and baker's yeast (Saccharomyces cervisiae) were favored as food stuff for rotifer cultures.Although bacterial counts increased in rotifer cultures fed with yeast, these numbers rearched maximum levels after protein selco treatment ( total bacteria count 92x106 cfu ml - 1 ;Vibrio spp.count 20x106 cfu ml -1 ; Pseudomonas spp.count 25x105 cfu ml -1 ).
