Evaluación de dos anestésicos y metodología de marcaje individual con microchip subcutáneo en Octopus vulgaris

[EN]The present work evaluates, on one hand, two anaesthetic agents to facilitate octopus handling concluding that a 1.5% of ethanol (96%) in sea water (22ºC) shows rapid anaesthetic-recovery time, indicating its suitability for this species. On the other hand, a protocol for implanting Octopus vulgaris with subcutaneous PIT tags is established and after 10 weeks a 94% retention was found with 100% survival. Retention rises to 98,6% when tagging animals weighing more than 500 g.

Crecimiento individual de Octopus vulgaris (Cuvier, 1797) alimentado con pienso húmedo experimental y boga (Boops boops, L. 1758)

[EN]The present work pretends to be the first step towards the development of a commercial diet for Octopus vulgaris. A one month experiment evaluated growth on two treatments, a wet experimental diet and a control (bogue), obtaining a daily growth rate of 1,6 and 16 g/day respectively. Octopuses were tagged and a better growth tendency was found in middle size animals in each experimental tank

Influencia de la técnica de congelación (nitrógeno líquido vs ultracongeladores de -152ºC) y variación individual sobre la calidad seminal en el dogo canario

[ES] En este estudio, se pretende valorar la calidad in vitro del semen canino congelado por un ultracongelador de -152 ºC, así como evaluar la variación individual en la calidad seminal en Dogos Canarios. Se testaron dos técnicas: (I) el semen era congelado y almacenado en nitrógeno líquido; (II) el semen era congelado y almacenado en un ultracongelador de -152 ºC. Tras la congelación, la motilidad, la vitalidad espermática y el porcentaje de morfoanomalías espermáticas no eran diferentes entre la técnica de nitrógeno líquido y el protocolo del ultracongelador. Por otro lado, la calidad seminal en fresco era similar entre machos; no obstante, en la calidad seminal post-congelación se observaron diferencias significativas (p<0.05) entre individuos, independientemente del procedimiento de congelación utilizado. Los resultados in vitro confirman que el ultracongelador de -152 ºC es una alternativa potencial frente al nitrógeno líquido para congelar y conservar semen canino.

Plant food supplement (PFS) market structure in EC Member States, methods and techniques for the assessment of individual PFS intake

The popularity of herbal products, especially plant food supplements (PFS) and herbal medicine is on the rise in Europe and other parts of the world, with increased use in the general population as well as among specific subgroups encompassing children, women or those suffering from diseases such as cancer. The aim of this paper is to examine the PFS market structures in European Community (EC) Member States as well as to examine issues addressing methodologies and consumption data relating to PFS use in Europe. A revision of recent reports on market data, trends and main distribution channels, in addition an example of the consumption of PFS in Spain, is presented. An overview of the methods and administration techniques used...
