| The effect of marination on the shelf life of smoked eel (Anguilla anguilla) was investigated. The fish was hot smoked at 80°C for 90 min and separated into two samples: Lot A was immersed in a solution containing 4% acetic acid, 4% lemon juice and 10% NaCl, then stored at 4°C during 7 days. After the marination process, samples were transferred to a diluted solution, containing 2% acetic acid, and 2% NaCl. Lot B was directly immersed in the same diluted solution. Chemical (total volatile basic nitrogen), physical (pH), microbiological (Total viable count, coliforms, pathogen staphylocoques, sulphate reducing bacteria and salmonellas) and sensory analyses were performed on both lots during the storage. The marination reduced considerably the bacterial... |

| El cultivo del camarón se ha presentado como una alternativa de producción de este crustáceo ante los altos costos de las faenas de pesca provocados por los altos precios del combustible y los bajos rendimientos de las capturas ante el agotamiento del recurso. En el presente trabajo se presentan varias tecnologías de procesamiento del camarón susceptibles de ser aplicadas para su comercialización, así como una alternativa de organización del proceso de manipulación y procesamiento industrial que contempla una inversión para el procesamiento en las propias camaroneras, la cual conlleva una disminución de los costos de producción. Como resultados se obtuvieron las tecnologías para la producción de camarón entero, entero precocido, entero... |

| Parasitized and non-parasitized hake fillets obtained at fish processing plants were compared in order to assess the efects of Kudoa rosenbuschi myxosporidia on muscle of Merluccius hubbsi. The following studies were carried out: a)incidence and severity of parasitism; b)proteolytic and spoilage at a histologic level; c)pH and proximal composition in parasitized and non-parasitized fillets; and c)parasitism action on gelified products. Gel strength, elasticity and organoleptic level in gelified products were lower for parasitized samples. Recommendations are put forward as to conditioning and cooling of the catch and subsequent processing in order to lessen the effects of parasitism. |

| La Commission Sous Régionale des Pêches (CSRP), qui est un organisme intergouvernemental de coopération halieutique dont l’objectif global est l’harmonisation à long terme, des politiques des pays membres en matière de préservation, de conservation et d'exploitation durable de leurs ressources halieutiques et le renforcement de leur coopération au profit du bien-être de leurs populations respectives, a obtenu par l’intermédiaire de la Banque mondiale, un Don du Fonds pour l’Environnement Mondial (FEM) et du Gouvernement du Japon, pour la préparation d’un Projet Régional des Pêches en Afrique de l’Ouest (PRAO) pour trouver une solution à la problématique susvisée. Ce projet implique 9 pays côtiers: la Mauritanie, le Cap Vert, le Sénégal, la Gambie, la... |

| El presente trabajo llama la atención a las recientes epidemias de intoxicación histamínicas reportadas en los Estados Unidos, debido al consumo del dorado (Coryphaena hippurus) o Mahi-Mah, contaminado. Esto dió como resultado la prohición de las importaciones de esta especie, proveniente de varios países entre ellos el Ecuador, y siendo el dorado una especie de relativa importancia económica en este país, dicha prohibición ha preocupado al sector pesquero. Los estudios llevados a cabo muestran claramente la susceptibilidad de esta especie a desarrollar histamina. Esto se debe principalmente a la temperatura a la que está expuesta, pues la demora antes de enhielar el pescado es la etapa crítica. Los resultados muestran un aumento exponencial de los niveles... |

| It is generally accepted, that a major constraint in the further development of marine fish and crustacean aquaculture, is the variable quality of eggs and larvae used for the hatchery-production of fry. Nonetheless, valid criteria to evaluate optimal egg quality have not been identified yet. Instead, particular indicators, are used, e.g. the fertilization and hatching rate, overall culture success during the first rearing period, etc., but these are not totally objective because hatchery-specific conditions may interfere. The biochemical composition of the egg may be one of the possible determinants of egg quality, which can be evaluated on a more objectie basis. In this respect, studied have been initiated to analyze in freshly-released eggs, the levels... |

| The assessment of the impact of pollution on the marine environment depends on the possibility of prediction either by comparison or more ideally by the analysis of time series which are long enough. Obtaining data for the construction of these time series should be one of the principal goals of monitoring. Parameters which are measured should have a low variability in time and in space or low frequency. The analysis of meiobenthic communities in the North Sea and the adjacent estuaries shows that harpacticoid copepods are especially suitable as the number and the nature of the species are stable and density, biomass, and diversity are characterized by the absence of variance in the high frequencies. Nematodes, though overwhelmingly abundant, are more... |

| A stress test is proposed for the evaluation of the physiological condition of fish larvae in nutritional studies. The test was used in a study of quantitative (n-3) highly unsaturated fatty acids (HUFA) requirements in larval <i>Lates calcarifer</i> and <i>Siganus guttatus</i>. It enabled to suggest fast intervention at reduced larval quality and allowed to prevent mass mortalities. The stress test offered valuable information for the quantification study of fatty acid requirements in marine fish larvae. In <i>Lates</i> demands for fatty acids were detected in metamorphosis. In <i>Siganus</i> on the other hand, the sensitivity of the larvae was considerably reduced after short (n-3) HUFA boosting of the... |

| Eight WEFTA laboratories participated in two series of intercomparison exercises on sulfite determination in tropical shrimps. Samples of tropical shrimps were spiked with sodium metabisulfite (Na<sub>2</sub>S<sub>2</sub>O<sub>5</sub>) and hydroxymethylsulfonate (HMS) at a level of 25-90 mg SO<sub>2</sub>/kg. Most of the laboratories determined the sulfite content with (modified) methods of Monier-Williams or De Vries et al. The overall mean recovery of sulfite was rather low (47-60%), which may be attributed to an irreversible reaction of sulfite with the tropical shrimps. The repeatability of the methods within the participating laboratories was good. However, reproducibility among the laboratories was... |

| Abstract Background: The study of the interactions between equipment, application methods, and spray mixtures is fundamental to optimize the application of pesticides. The determination of the best combination of these factors can reduce the drift during the application of the herbicide 2,4-dichlorophenoxyacetic acid (2,4-D). Objective: The objective this paper is to study the influence of nozzle models, working pressures, and surfactant adjuvant in reducing the drift of 2,4-D. Methods: The spectrum of nozzle drops was determined for a conventional flat jet; flat jet with air induction; double plane jet with air induction; deflector flat jet with air induction; and an empty cone with air induction at pressures of 200, 300, 400, and 500 kPa. This was... |
