Weaning of Senegalese sole (Solea senegalensis) postlarvae to an inert diet with a co-feeding regime

The objective of this study was to evaluate the weaning success of Senegalese sole, Solea senegalensis, postlarvae when cofed a compound diet, by means of the analysis of growth parameters (relative growth rate [RGR] and condition factor [K]), survival, protein and lipid content. Total ammonia in th...

Total ammonia in the rearing water was also measured. The experiment lasted for 46 days (36 to 82 days posthatching). One group was fed only with enriched Artemia sp. metanauplii (Artemia treatment), whereas in another group, the Artemia sp. metanauplii were gradually replaced by the International Council for the Exploration of the Sea (ICES) diet over a period of 39 days (ICES treatment). Postlarvae were sampled on rearing days 0, 9, 23, 30, 39 and 46 for growth and biochemical analysis. Water was sampled on rearing day 30 during a 24-h cycle in both treatments. Postlarvae from the ICES treatment were weaned, though by the end of the experiment the Artemia treatment exhibited significantly higher values for growth, RGR, K and survival rates (P < 0.05). No significant differences were observed concerning total lipid content. Protein content was significantly higher for the Artemia treatment after 46 days of rearing (P < 0.05). The total ammonia nitrogen concentration in the water increased after each meal and remained below a harmless level for postlarvae. El objetivo de este estudio consistió en evaluar el éxito del destete de postlarvas del lenguado senegalés, Solea senegalensis, utilizando un régimen de coalimentación. El estudio se realizó mediante el análisis de parámetros de crecimiento (tasa de crecimiento relativa [RGR] y factor de condición [K]), supervivencia y contenido de proteínas y lípidos. La concentración del amonio total en el agua de cultivo también fue analizada. El experimento se realizó durante 46 días (de 36 a 82 días posteclosión). Un grupo de postlarvas se alimentó únicamente con metanauplios de Artemia sp. enriquecidos (tratamiento con Artemia), mientras que en otro grupo los metanauplius de Artemia sp. fueron gradualmente substituidos por la dieta del Internacional Council for the Exploration of the Sea (tratamiento ICES) durante un periodo de 39 días. Las postlarvas se muestrearon durante los días 0, 9, 23, 30, 39 y 46 de cultivo para el estudio de crecimiento y el análisis bioquímico Las muestras de agua se tomaron el día 30 de cultivo durante un ciclo de 24 h en ambos tratamientos. Las postlarvas del tratamiento ICES fueron destetadas, aunque al final del experimento se registraron valores significativamente mayores en relación al crecimiento, RGR, K y tasas de supervivencia (P < 0.05) en el tratamiento con Artemia. No se observaron diferencias significativas en el contenido total de lípidos. El contenido de proteínas fue significativamente mayor en el tratamiento con Artemia a los 46 días de cultivo (P < 0.05). La concentracion de amonio total en el agua se incrementó después de cada toma de alimento pero se mantuvo por debajo del nivel tóxico para las postlarvas de peces marinos.
