Se evaluó el efecto de las harinas de Salicornia bigelovii (SA) y Scomber japonicus, semiprocesada (HPS) como ingredientes en la formulación de dietas para camarón azul Litopenaeus stylirostris, en cultivo súper-intensivo. Se formularon tres diferentes dietas isoproteicas (40%) e isocalóricas (6 kcal g-1): (DSA), (DHPS), basal (DBA) y una dieta control (DCO). El peso obtenido con DSA y DHPS (0,9 ± 0,014 y 0,8 ± 0,015 g) fue similar a la dieta comercial DCO (0,9 ± 0,07 g), no existieron diferencias significativas (P > 0,05) en talla (cm), peso (g) y factor de conversión alimenticio (FCA). Los resultados obtenidos sugieren que DSA y DHPS son factibles de utilizar en la formulación de dietas para camarón por ser ingredientes de bajo costo que pueden sustituir a la harina de maíz y pescado tradicional, respectivamente sin efectos detrimentales en el crecimiento y supervivencia.The effect of semi-processed fishmeals (HPS) made using Salicornia bigelovii (SA) and Scomber japonicusas ingredients in the formulation of diets for blue shrimp Litopenaeus stylirostris undersuper-intensive farming was evaluated. Three different isoproteinic (40%) and isocaloric (6 kcal g-1) diets were formulated: DSA, DHPS, basal (DBA); a fourth control diet (DCO) was also used. The weights obtained with DSA and DHPS (0.9 ± 0.014 and 0.8 ± 0.015 g) were similar to those obtained with the commercial diet (DCO; 0.9 ± 0.07 g), and no significant differences (P > 0.05) were found for size (cm), weight (g), and the feed conversion ratio (FCR). The results suggest that the use of DSA and DHPS in the formulation of diets for shrimp is feasibleas these are low-cost ingredients that can be used as substitutes for cornstarch and traditional fishmeal, respectively, without detrimental effects for shrimp growth and survival.
