“…During the past three decades, enormous efforts have been made to develop microdiets to replace live feed, both rotifers and Artemia, as complete or partial diets for marine fish (Kolkovski, Curnow & King, 2004;Koven, Kolkovski, Hadas, Gamsiz & Tandler, 2001). Many studies investigated the suitability of different diets for larviculture of meagre (G€ ultepe et al, 2016;Saavedra et al, 2016). Although there were substantial achievements in reducing the reliance on live feeds, microdiets cannot completely replace them.…”

Summary In hatcheries, meagre Argyrosomus regius larvae still depend on an adequate supply of rotifers and Artemia, as no artificial diet can totally fulfil their nutritional requirements. However, production of live feed is highly expensive and demands intensive labour and specific facilities. This study investigated the effect of a dietary regime without the use of rotifers, to simplify the meagre larval rearing protocol. Two feeding treatments (T1 & T2) are compared to investigate their effects on survival and growth of meagre larvae. In T1, larvae were fed rotifers from 2 to 5 days post hatch (dph), and Artemia from 4 to 15 dph. In T2, larvae were kept under dark conditions and fed Artemia from 6 to 15 dph. Standard larval length (SL) was significantly higher in T1 (p < .01) until 8 dph in comparison with larvae reared initially without rotifers. No significant difference in SL was found among treatments (p = .187) at 15 dph. Significant difference was found among treatments in survival rate at 15 dph (p < .003). The survival rate observed at 15 dph in T2 (30 ± 4.2%) represents an important finding, although the highest survival rate was observed in T1 (45.0 ± 3.4%). This study showed that it is possible to conduct larval rearing of meagre without using rotifers. Nevertheless, further research efforts are still needed to improve these results in comparison with the common larval rearing protocol.
