Development of a lipid-enrichment technique for <i>Artemia</i> juveniles produced in an intensive system for use in marine larviculture OMA
Dhont, J.; Lavens, P.; Sorgeloos, P..
Although there exists an obvious inclination to replace live larval food by formulated feeds, <i>Artemia nauplii</i> are still essential in the larviculture of marine fish species. So far, on-grown <i>Artemia</i> are rarely used in larviculture although they offer several advantages over <i>Artemia nauplii</i>: e.g. they contain a higher individual protein and energy content thus improving the fish larvae's energy budget; an equal amount of live food is reached with far less individuals thus a considerable saving of <i>Artemia</i> cysts; their composition of (n-3) highly unsaturated fatty acids (HUFA) may easily be improved by applying enrichment techniques. This study deals with the development of...

Microbial control of the culture of <i>Artemia</i> juveniles through preemptive colonization by selected bacterial strains OMA
Verschuere, L.; Rombaut, G.; Huys, G.; Dhont, J.; Sorgeloos, P.; Verstraete, W..
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...

Monitoring Biolog patterns and <i>r/K</i>-strategists in the intensive culture of <i>Artemia</i> juveniles OMA
Verschuere, L.; Dhont, J.; Sorgeloos, P.; Verstraete, W..
<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...

Preparation and use of <i>Artemia</i> as food for shrimp and prawn larvae OMA
Dhont, J.; Lavens, P.; Sorgeloos, P..
The brine shrimp,<i>Artemia</i> has played a significant role in the expansion of the commercial production of shrimp and prawn during the last decade. Being an off-the-shelf and easily usable live food,<i>Artemia</i> is the main alternative for the natural diet of shrimp larvae. It appeared in the late 1970s that the nutritional value of <i>Artemia</i>, especially for marine organisms, is not constant, but varies both geographically and temporally, causing unreliable outputs in marine larviculture. Through multidisciplinary studies in Japan and by the International Study on <i>Artemia</i>, both the causes for nutritional variability in <i>Artemia</i> and methods to improve poor-quality...
