| Abstract: | The possibility to replace or reduce rotifer use with a microparticle diet (MPD) from first feeding in yellowfin seabream larvae was investigated. The experiment consisted of five treatments, a rotifer (100%) control treatment (100R), three experimental treatments, which received a fixed ration of MPD supplemented with 75%, 50% and 25% of the amount rotifer fed in the control treatment (treatments 75R‐MPD, 50R‐MPD and 25R‐MPD respectively), and finally a treatment with the fixed MPD ration only (treatment 0R‐MPD). The results indicated that feeding regimes 100R, 75R‐MPD and 50R‐MPD did not differ significantly in the total length, final survival and stress test resistance. The highest dry weight was achieved in treatments 100R and 75R‐MPD at the end of the experiment compared with treatments 50R‐MPD, 25R‐MPD and 0R‐MPD. The 0R‐MPD treatment showed the lowest growth and survival. Yellowfin seabream larvae were able to ingest inert food directly from the moment of first feeding. |
