| En los laboratorios de producción de postlarvas de camarón se suministra, en los estadios de protozoea y mysis, alimento vivo para garantizar buenos resultados en el cultivo sin embargo, el empleo de alimentos artificiales posibilita reducir la costosa dependencia de las algas y los quistes de Artemia ( Wouters et al, 2004). Aunque los resultados alcanzados con diferentes dietas artificiales en el cultivo larval son satisfactorios, aún existe gran preferencia por la utilización del alimento vivo. Sin embargo, en los últimos años con vistas a disminuir los costos de producción, la contaminación y agilizar el proceso productivo, diferentes empresas se han dado a la producción de alimentos artificiales para sustituir parcial (Fegan, 1992) o totalmente el... |

| The feasibility of substituting soybean meal for ¢shmeal diets for juvenile white shrimp Litopenaeus schmitti (0.35 0.01g) was evaluated, and an adequate substitution level was determined. Five diets were evaluated using 46%, 59%, 75%, 88% and 100% substitution levels. Pellet water stability was signi¢cantly a¡ected by dietary soybean content (Po0.05). Increased soybean content produced lower pellet stability, ranging from a dry matter loss of 14^ 22% after a 2-h immersion, and 20^33% after an 8-h immersion. After 52 days, signi¢cant di¡erences (Po0.05) were found in shrimp weight, feed conversion ratio and protein e⁄ciency ratio. The values were 0.64^1.06 g, 2.8^7.9 and 0.45^1.21, respectively, for the three measurements. Overall, better results were... |

| To evaluate the effect of Spirulina platensis inclusion in microdiets for white shrimp Litopenaeus schmitti larvae, a completely randomized experimental design was developed with 4 treatments and three replicates. Diets with 3 inclusion levels (0, 2.5 and 5%) were prepared. A control was fed Artemia nauplii. Larvae were fed for 120 hours from mysis I to postlavae 1 every 4 h, and water quality parameters were measured daily. At the end of the experiment survival was determined, and the development index of the larvae was calculated. The chemical score of the diet was also determined, using the L. schmitti postlarvae amino-acid pattern as reference. Triptophan and hystidine were the first and second limiting amino acids in the diets. Survival was around 80%... |
