The aim was to evaluate diets with biological cornmeal silage in order to improve the productive performance of Cryphiops caementarius river shrimp. Shrimp were grown in 12 aquariums (55 L). Shrimp were randomly stocked (32 m-2) and fed diets containing 4.2%, 8.4% and 12.5% cornmeal silage and a control diet without silage. Experiment lasted 60 days. Physical, organoleptic and chemical quality of silage and the diets were analyzed at beginning. Silage had 8.57% protein; 16.49% total lipids; 1.45% fiber; 2.25% ash; 71.24% carbohydrates, and the pH was 4.40. Increase in level of corn silage (0% to 12.5%) in diets caused an increase in carbohydrates (38% to 47%) and a decrease in lipids (11% to 14%). Shrimp survival was similar (p > 0.05) between treatments (> 88%). Diet with 12.5% corn silage caused higher growth rates shrimp weight (p < 0.05) than those fed a diet without silage;...

El objetivo fue determinar el efecto de dietas con ensilado biológico de harina de Zea mays en el crecimiento de machos adultos de Cryphiops caementarius (Crustacea: Palaemonidae). Los camarones se cultivaron en 12 acuarios de 50 L, con sistema de recirculación de agua y filtro biológico. Los camarones fueron sembrados al azar (32 camarones m-2) y alimentados, dos veces al día, con dietas conteniendo 25%, 50% y 75% de harina de ensilado biológico de maíz y el control sin harina de ensilado, en todos los casos con tres repeticiones. La calidad física, organoléptica y química del ensilado y de las dietas fueron analizadas al inicio. El ensilado de maíz fue aceptado por todos los camarones. La composición química del ensilado fue de 8.57% de proteínas, 16.49% de lípidos totales, 1.45% de fibra, 2.25% de cenizas, 71.24% de carbohidratos, 15.98% de humedad y el pH fue de 4.40. E...
