Harina de erizo de mar (Diadema antillarum) com ingrediente alternativo en piensos para bocinegro (Pagrus pagrus): efecto sobre el crecimiento y utilización de la dieta

[EN]The effect of dietary inclusion of sea urchin meal (Diadema antillarum) on growth and feed utilization was investigated in a growth trial with red porgy (Pagus pagrus) of 208g initial body weight, during 6 month feeding period. High quality fish meal and fish oil diet was used as a control (Diet C); urchin meal was included at 8% and 16% dietary levels (EM8 and EM16). Compared to the control diet higher values for absolute and relative final weight and SGR were obtained either for fish fed EM8 and EM16 diets; for the latter diets values for FCR and final HSI were significantly smaller respect to those for the control diets. No differences were found among diets for the total feed intake, VSI and K factor. Obtained results indicate the suitability of the sea urchin meal as alternative ingredient in diets for the red porgy, improving fish growth and feed utilization. More studies are being done at the moment in red porgy and other fish species in order to better determine the optimum dietary levels taking into account other important culture and quality parameters.

Efecto de la primera alimentación en la supervivencia y el crecimiento de crías de caballito de mar, Hippocampus hippocampus (Linnaeus, 1758)

[EN]Effects of first feeding on survival and growth of Atlantic seahorse juveniles, Hippocampus hippocampus, (Linnaeus, 1758). In this study, two experimental protocols were tested: a first treatment (RA), in which larvae were fed exclusively on rotifers until day 5, and then on Artemia, and a second treatment (A) where larvae were only fed on Artemia. We attempted to improve survival and growth by comparing different diets in the first days of life. The results showed excellent survival (60% average) and growth in juveniles exclusively fed with Artemia, with better values than those obtained by other authors for this species. In comparison, high mortality and poor growth were observed on the first days in larvae fed rotifers.
