<i>Artemia</i> juveniles were cultured under intensive conditions in three series of six tanks at different times. Both plate counts and Biolog GN microtitre plates were used to monitor the microbial community. Repetitions of the <i>Artemia</i> cultures in time revealed significant differences in Biolog patterns and bacterial counts, showing that normal culture practices, including chlorination of the sea water, does not allow control of the associated microbial community. However, the similarity among the Biolog fingerprints of all 18 tanks as determined by the Pearson correlation coefficient was always high. Both observations together indicate that the microbial community which colonizes the culture tanks seems to be determined by... |

The effect of bacterial strains on the growth rate of rotifers, Brachionus plicatilis, was determined under monoxenic conditions. The first objective was to obtain sterile rotifer cultures starting from rotifer resting eggs using merthiolate or glutaraldehyde as disinfectant. Sterile rotifer cultures were obtained, without affecting the hatching ability of the resting eggs, when 0.05 µl/l glutaraldehyde was used. This disinfection procedure was used to examine the effect of 20 bacterial strains, isolated from well-performing live-feed production systems, on the population growth rate of rotifers cultured under monoxenic conditions. Five out of the 20 bacterial strains tested were able to improve significantly the asexual reproduction of rotifers. The... |

The use of juvenile <i>Artemia</i> as feed in aquaculture and in the pet shop industry has been getting more attention during the last decade. In this study, the use of selected bacterial strains to improve the nutritional value of dry food for <i>Artemia</i> juveniles and to obtain control of the associated microbial community was examined. Nine bacterial strains were selected based on their positive effects on survival and/or growth of <i>Artemia</i> juveniles under monoxenic culture conditions, while other strains caused no significant effect, significantly lower rates of survival and/or growth, or even total mortality of the <i>Artemia</i> . The nine selected strains were used to preemptively colonize the... |
