“…Caso contrario, sucedió con las dietas DT-40 y DT-44, donde se determinaron mayores cantidades de los ácidos linoleico (18:2n-6) y linolénico (18:3n-3). En efecto, dietas para peces marinos tienen un alto porcentaje de lípidos y en especial de ácidos grasos de cadenas largas (>20 átomos de carbono), puesto que estos peces requieren mayores concentraciones de HUFAs del tipo n-3 (EPA y DHA) (López et al, 2009;Sargent et al, 1999), debido a que en tejidos de peces marinos se ha encontrado mayor composicion de estos ácidos grasos y no lo pueden sintetizar, a diferencia de peces dulceacuicolas que obtienen sus requerimientos de ácidos grasos esenciales a partir del suplemento del ácido linoleico y linolénico (Bell & Sargent, 2003), es decir pueden ser biosintetizados.…”

-40). Las evaluaciones biométricas muestran que mayor crecimiento, conversión alimentaria y factor de condición se obtuvieron en A. scapularis alimentadas con la dieta DM-48 (P < 0,05). Sin embargo, la relación talla-peso y consumo de alimento-talla fueron similares entre los tratamientos dietarios. Por otro lado, menores concentraciones de proteína y mayores de lípidos se obtuvieron en el músculo de juveniles de A. scapularis alimentados con las dietas DM-48 y DF-50 (P < 0,05), respectivamente. El análisis de componentes principales mostró una mayor correlación entre peces alimentados con la dieta DM-48 y el contenido muscular de DHA, EPA y ARA; y con el crecimiento. Los resultados sugieren que la formulación de alimentos para juveniles de A. scapularis debería contemplar al menos de 48% de proteína y concentraciones importantes de DHA, EPA y ARA para su adecuado crecimiento de esta especie.

The growth, muscle proximal composition and fatty acid profile of juveniles of Anisotremus scapularis fed with four commercial diets were evaluated. During 106 days, 200 fishes, were distributed in four treatments, fish were fed with commercial diets identified by their protein content: 50% (DF-50), 48% (DM-48), 44% (DT-44) and 40% (DT-40). Biometric evaluations showed that higher growth (P < 0.05), feedconversion and condition factor were obtained in A. scapularis fed with DM-48. However, both length-weight and food intake-size relationships were similar among dietary treatments. Lower (P < 0.05) protein and higher (P < 0.05) lipid concentrations in muscle of A. scapularis fed with DM-48 and DF-50 were obtained, respectively. Principal component analysis showed a higher correlation between fishes fed with DM-48 and DHA, EPA, and ARA muscle contents as with growth. Our results suggest that the food formulation for juveniles of A. scapularis should include at least 48% protein and significant concentrations of DHA, EPA and ARA for a proper growth of this species.

“…At the end of the trial, BW and BL of all the experimental fish were measured individually to determine their growth performance while some fish (n=18) from each treatment were sacrificed for biochemical analysis and to estimate viscerosomatic index (VSI), hepatosomatic index (HSI) and the intraperitoneal fat (IPF). The growth performance and body indexes (Ng et al, 2008;López et al, 2009;Bicudo et al, 2010) were estimated as followed:…”

“…Dietary lipid is a source of energy and essential fatty acids that cannot be de novo synthesized by fish (López et al, 2009). Carnivorous fish are known to utilize protein as energy more efficiently than lipids and carbohydrates (Du et al, 2005).…”

“…However, several studies report that increasing dietary lipid within a certain limit can improve the growth and protein utilization of fish through the protein sparing effect by lipid (Peres and Oliva-Teles, 1999;López et al, 2009;Kim et al, 2010), where dietary lipid is used as the main energy source in the overall energy expenditure while dietary protein is utilized for growth (Xu et al, 2001). On the contrary, limited or no protein sparing effect is also reported in many fish species such as grass carp Ctenopharyngodon idella, tiger puffer Takifugu rubripes and turbot Psetta maxima where increasing levels of dietary lipid did not bring any beneficial effects on growth, protein efficiency ratio and feed utilization but resulted in a significant lipid accumulation in the body (Regost et al, 2001;Du et al, 2005;Kikuchi et al, 2009 …”

The present study was conducted to investigate the growth performance and feed utilization of marble goby,Oxyeleotris marmorata, juveniles fed with different levels of dietary lipid. Juvenile fish (initial mean weight 2.76 g) were fed with is onitrogenous diets including 10, 14, 18 and 22% of dietary lipid in triplicate groups for 15 weeks. The results showed that the highest growth performance and feed utilization was observed in fish fed D10. The increase of dietary lipid from 10 to 22 % did not improve growth, feed conversion rates, protein efficiency ratio, nitrogen retention efficiency, and apparent digestibility coefficients of protein and lipid (P>0.05). The increase of dietary lipid had significantly increased the whole body and hepatic lipid, hepato-somatic index, visceral-somatic index and intraperitoneal fat levels (P<0.05). These results suggest that there is no protein sparing effect of high dietary lipid levels in O. Marmorata due to possibly a limited ability to utilize dietary lipid. Based on the second-order polynomial regression analysis on protein efficiency ratio, ca. 12.1% of dietary lipid appears to be optimumfor growth from 2.76g to 13.76g body weight of O. marmorata juveniles.
