| Plasma cortisol and glucose levels were measured in 36 adult Nile tilapia males, Oreochromis niloticus (standard length, mean ± SD, 14.38 ± 1.31 cm), subjected to electroshock and social stressors. Pre-stressor levels were determined 5 days after the adjustment of the fish to the experimental aquaria (1 fish/aquarium). Five days later, the effects of stressors on both cortisol and glucose levels were assessed. The following stressors were imposed for 60 min: pairing with a larger resident animal (social stressor), or a gentle electroshock (AC, 20 V, 15 mA, 100 Hz for 1 min every 4 min). Each stressor was tested in two independent groups, one in which stress was quantified immediately after the end of the 60-min stressor imposition (T60) and the other in... |

| The behaviour of fecal bacteria was investigated in a turbid estuary which is also a shellfishing area. Sediments are polluted by sewage by the way of settlement, fecal bacteria mixed with estuarine water being able to survive a very long time (T90 are about several days). By measuring the increase of salt tolerance of the strains grown in natural estuarine organic matter, it was demonstrated that Escherichia coli is able to support the salinity of coastal water. Moreover, because light penetration is obstructed by suspended matter, the solar bactericidal effect is very low. A close relationship between T90 and light intensity received by the bacteria is found. These mechanisms can explain... |

| El cultivo de trigo (Triticum aestivum) es el de mayor importancia en el valle de Mexicali, México. Con base en su composición química, la planta completa de trigo es considerada de calidad similar a la alfalfa (Medicago sativa) o al ballico (Loliunt multiflorum). Por ello, se comparó la digestión del heno de trigo para grano cosechado en dos estados de crecimiento (45 y 90 d) con henos de alfalfa (floración media) y ballico (120 d después de sembrado). Cuatro novillos Holstein (326 ±20 kg PV) con cánulas ruminales y duodenales se usaron en un diseño cuadro latino 4X4. Los tratamientos (henos) fueron: 1) alfalfa, 2) ballico, 3) trigo cosechado a 45 d (T45d) y 4) trigo cosechado a 90 d (T90d). Los novillos alimentados con... |

| ABSTRACTThe cardiopulmonary changes in propofol- or thiopental-anesthetized dogs induced to pulmonary hypertension (PH) were evaluated. Twenty adult animals were randomly assigned to two groups: propofol group (PG) and thiopental group (TG). In PG, propofol was used for induction (8(0.03mg.kg-1) and anesthesia maintenance (0.8mg.kg-1.minute-1), while, in TG, thiopental was used (22±2.92mg.kg-1; 0.5mg.kg-1.minute-1, respectively). Mechanical ventilation using time cycle was started. PH was induced by administration of serotonin (5HT) (10µg.kg-1 and 1mg.kg-1.hour-1) through a thermodilution catheter positioned in the pulmonary artery. The measurements were performed before administration of 5HT (T0), after 30 minutes (T30), then at 15-minute intervals (T45,... |

| Most European fishing fleets will need to drastically reduce their unwanted catches to comply with new rules of the common fisheries policy. A more practical way to avoid increasing on-board sorting time and issues linked to storage capacity is to prevent unwanted catches in the first place. We assessed the selectivity properties of an experimental fishing gear that combined a 100 mm T90 cylinder with 130 meshes in the extension and a 100 mm T90 codend of 33 meshes (experimental gear) compared to a 100 mm diamond mesh extension and codend (control gear) during commercial trips using twin trawls. Analysis of the relative size composition of catches indicated a significantly higher... |

| To improve the knowledge of the survival of enteric viruses in a marine environment, the influence of physico-chemical parameters (temperature, UV, salinity) on the survival of infectious poliovirus 1 and hepatitis A Virus (HAV) in seawater was first studied, the influence of suspended solids (SS) on poliovirus adsorption and survival in seawater was then evaluated and the detection of rotavirus genome in environmental samples (shellfish, river water, treated wastewater) was finally investigated. The results show that temperature has a major impact on virus survival in seawater as the time necessary to inactivate 90 % of the virus (T-90) is 671 days at 4 degrees C and only 25 days at 25 degrees C. Ultraviolet light (42 mW... |

| Este trabalho teve por objetivo avaliar o efeito de doses de composto orgânico nas propriedades do solo, no teor de nutrientes e qualidade das sementes de alface. O delineamento experimental utilizado foi blocos ao acaso, com cinco tratamentos (T0: sem composto orgânico; T30: 30 t ha-1; T60: 60 t ha-1; T90: 90 t ha-1 e T120: 120 t ha-1 de composto orgânico) e cinco repetições. Não houve efeito significativo de doses de composto orgânico para os teores de todos os macronutrientes nas sementes, assim como na qualidade fisiológica (germinação e vigor). Observou-se aumentos lineares nos teores de matéria orgânica, cálcio, magnésio, soma de bases, CTC e saturação por bases do solo ao final do ciclo da cultura. |

| In the Bay of Biscay, the selective properties of otter trawls have mainly been studied with regard to single species. However, for bottom trawl multispecific fisheries targeting fish, it remains challenging to find a selective device capable of limiting catches of small individuals of several species without commercial losses. The present study focuses on an innovative technical solution to reduce catches of undersized individuals in a multispecies bottom trawl fishery in the Bay of Biscay. We tested a cylinder made of 100-mm diamond meshes turned at 90°, namely T90 inserted in the extension piece. We present the selectivity results obtained for six commercial species. This device allows the escape of small Solea solea,... |

| FEMNET, a numerical tool based on the finite element method, was used to estimate the shapes of four different designs of trawl cod-ends during fishing operations. Compared to a traditional diamond-mesh cod-end the design differences were the following: (i) the netting orientation was turned by 90 degrees (T90), (ii) the number of meshes in the circumference was reduced by 50% or (i) and (ii) were combined. The cod-end shape estimates were then entered into the simulation tool PRESEMO, to estimate their influence on the selectivity processes in the cod-end. This enabled us to predict how these design alterations - alone or combined - may act on the selectivity of each cod-end under identical fishing conditions. For... |

| O objetivo deste trabalho foi avaliar a viabilidade técnica de se usar a produção de leite em parte da lactação, em vez da produção acumulada até 305 dias, para obtenção dos valores genéticos preditos (VG). Foram comparadas as classificações de touros e vacas pelos seus VG para produção de leite até 90(T90), 150(T150) e 210(T210) dias de lactação, em relação à classificação, com base nos VG calculados, usando-se a produção até 305(T305) dias. Adotou-se um modelo animal que incluiu os efeitos fixos de rebanho-ano, época, idade da vaca ao parto e grupo genético e os efeitos aleatórios do animal, do meio permanente e do resíduo. Estimativas de herdabilidade e repetibilidade para T90, T150,... |

| A mathematical model of the the Morlaix Estuary has been set up, which provides a knowledge of currents, dispersion and bacterial contamination due to inputs from a sewage treatment plant (STP). Measured die-off rates appear very low (T90 from two days to several days). The model confirms these values and shows that physical dilution factors are responsible for a bacterial contamination decrease about one hundred times faster than mortality. The model is then used to seek ways of improving the present situation. It concludes that the best choice would be to increase the STP efficiency. |
