Discards refer to the part of the catch not retained on board during commercial fishing operations, but returned to the sea. The proposed European Union Common Fisheries Policy reform, to be implemented in 2014, sets out a gradual elimination of discards by reducing unwanted catches and ensuring that all catches are landed. To develop successful discard mitigation measures, it is necessary to identify the reasons for discarding. Here, we have developed a simple model that can be applied to data from observer programmes (ObsPs) to establish the contribution of different drivers of discarding behaviour. The analysis makes inferences on the causes of discarding by partitioning discards into four categories based on the length of the fish and the associated... |

Las toxinas marinas han proporcionado una variedad de compuestos capaces de ejercer acciones específicas y potentes a nivel de canales iónicos activados por voltaje o por neurotransmisores. Puesto que los canales iónicos participan en los mecanismos básicos de funcionamiento del sistema nervioso y que alteraciones funcionales y estructurales asociadas a éstos pueden correlacionarse con diferentes patologías neurológicas, neuromusculares y cardiovasculares, las toxinas pueden jugar un papel muy importante tanto como reactivos biológicos para la investigación biomédica, como para el diseño de nuevos fármacos a emplear en la terapéutica médica. |

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%... |

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... |
