Abstract:

Studies were carried out to determine the effect of using the rotifer, Brachionus plicatilis (Muller) (S-type), subjected to different treatments on the growth and survival of blue-fin sea bream, Sparidentex hasta (Valenciennes), larvae. This was to illustrate the role of mixed algae added to the oil enrichments for the treatment of the rotifers to improve the sea bream larval survival. The highest sea bream larval survival (P<0.05) was obtained while feeding the larvae with rotifers enriched in a mixture of algae plus half the recommended dose of Super Selco and DHA Protein Selco. No significant difference (P>0.05) in the larval growth was observed between different treatments. However, larval survival was significantly high (P<0.05) when rotifers were not treated with antibiotics. The results show that there is no need to use antibiotics to treat the rotifers before feeding the blue-fin sea bream larvae, providing that the rinsing procedure for rotifers used in this study is followed.
