| Results of the inclusion of GICABU and torula yeast in the diet for the Caribbean white shrimp (Litopenaeus schmitti) juveniles and cachaza oil in postlarvae diet are presented. Three completely randomised experimental designs were carried out to evaluate practical and semipurified diets, in juveniles and postlarvae respectively, with different by-products inclusion levels. Food was accepted and consumed in all the experiments. Shrimps reached a significantly higher growth (P<0.05) when torula yeast was included at 15, 20 and 25 % in diet, thus demonstrating the feasibility of the partial fish meal substitution. No significant differences were found (P>0.05) when GICABU was included up to 10 % in juvenile diet. Total replacement of sunflower oil by... |

| This study determined the effect of different shrimp head meal (SHM) levels (0, 5, 15, 25 and 30%) in practical diets for Caribbean white shrimp juveniles Litopenaeus schmitti (0.29 ± 0.0025 g). A totally randomized experimental design was carried out under laboratory conditions during 54 days. There were no significant differences (p > 0.05) in survival of shrimps in all treatments evaluated. This result indicated that SHM included at 5, 15 and 25% in diet promoted growth. The relation of SHM inclusion level in diet with final weight (FW), food conversion rate (FCR) and protein efficiency ratio (PER) were described by the following quadratic equation: FW = 0.8023 + 0.0604 S - 0.0018 S2, 2 =0.81; FCR = 8.0019 - 0.6081 S + 0.0164 S2, R2 =0.82 and PER =... |

| With the objective to determining the effect of different animal and plant protein ratios in white shrimp juvenile Litopenaeus schmitti diet, a totally randomized design was carried out at laboratory scale during 66 days. Five isonitrogenous and isocaloric practical diets were tested, with animal protein:plant protein ratios of 1:0, 2:1, 1:1, 1:2 and 1:1. Shrimps fed with food that contains only plant protein reached the smaller growth (p < 0,05). The histological analysis has shown degeneration and hypertrophy of the hepatopancreas when animal and plant protein ratio was 1: |

| Se identificó una especie de camarón exótico como Penaeus monodon, camarón tigre gigante, mediante tres ejemplares hembras capturados en lagunas costeras de Tunas de Zaza, golfo de Ana María, Cuba. La talla varió entre 270 mm a 290 mm de longitud total (Lt), con un peso entre 140 g a 230 g. La presencia de la especie significa una adaptación a las aguas cubanas y constituye una perspectiva positiva para su cultivo. |

| Con el objetivo de optimizar el empleo del alimento balanceado en el engorde de Litopenaeus schmitti, se desarrollaron cuatro diseños experimentales a escala piloto y comercial en estanques de tierra fertilizados para evaluar: (A) interacción entre tasas de alimentación, niveles de proteína y densidad de siembra; (B) esquemas de alimentación; (C) interacción entre tasas y esquemas de alimentación; (D) escala comercial con los mejores resultados alcanzados. No se observó interacción entre los factores tasas de alimentación, densidad de siembra y calidad del alimento, sin embargo una interacción significativa se obtuvo entre niveles proteicos y densidades de siembra (p<0.05), así como entre las tasas de alimentación ensayadas. Los camarones alcanzaron... |

| Con el objetivo de evaluar el efecto aglutinante del concentrado de pectina de cítrico (CPC) en el alimento para camarón, se desarrolló un diseño experimental completamente aleatorizado con cuatro tratamientos y tres réplicas por cada uno, en condiciones controladas. Las dietas se elaboraron con 0; 2; 5 y 7 % de CPC. Las pruebas de estabilidad del alimento se realizaron introduciendo 1 g de cada alimento, en bolsas de 0,1 mm de luz de malla previamente pesada y se colocaron en agua de mar (35 ups y 27 ºC), durante 1; 12 y 24 h. Al final de cada intervalo de tiempo, los alimentos se secaron y pesaron para calcular peso seco, pérdida de materia seca y absorción de agua. Con el empleo del CPC, los alimentos alcanzaron una estabilidad superior al 80 %... |
