Resumen

ACOSTA-RUIZ, Manuel de J.; PANIAGUA-MICHEL, J; OLMOS-SOTO, J  y  PAREDES-ESCALONA, E. First record on the use of Salicornia bigelovii and Scomber japonicus fishmeals as feed for Litopenaeus stylirostris under super-intensive farming. Lat. Am. J. Aquat. Res. [online]. 2011, vol.39, n.3, pp.409-415. ISSN 0718-560X.

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.
