dc.description.abstractThe senegal sole (Solea senegalensis) is a potential culture species in salt water ponds in south Spain and Portugal. However, growth of an industry around this species is constrained by poor survival during weaning from live Artemia onto artificial diets. This paper describes the influence of larval conditioning with inert diets on weaning performance. Mixed diets of commercial formulated feed and live prey (rotifers and Artemia) allowed larvae to develop from first feeding to metamorphosis without significant differences (P>0.05) in specific growth rate (SGR) (18.8%±1.2 and 18.1%±2.2) and survival (61.5%±10.6 and 61.1%±9.4) compared to larvae fed live feed alone (SGR of 18.4%±1.1 and survival of 71.6%±25.9). In metamorphosed fish, however, significant differences (P<0.05) in survival after weaning onto commercial feeds occurred after 50 days of culture, according to previous co-feeding with live and inert feeds during the larval stages. There was no growth or survival in fish weaned without any previous larval co-feeding. Metamorphosed fish previously fed a 1:1 ratio of live–inert feed during larval stages, had a similar SGR (5.1%±0.1, P>0.05) after weaning (day 70) to that obtained for fish that remained all the time on Artemia (5.3%±0.1). The SGR after weaning significantly decreased (3.4%±0.3, P<0.05) when the larval co-feeding regime had a higher proportion (2:1) of live feed. Survival for the weaning period was significantly lower (P<0.05) in weaned fish (39.0%±4.2 and 34.0%±11.3 for 2:1 and 1:1 live:inert larval co-feeding) compared to fish that remained on live feed (78.5%±5.0). This study demonstrates the feasibility of early weaning of S. senegalensis and that larval co-feeding enhances growth and survival after weaning.es_ES
