Abstract
El progreso de nuestra sociedad se debe en gran medida a la generación de una ingente cantidad de sustancias químicas, muchas de las cuales tiene su destino final en los ecosistemas acuáticos continentales con el consiguiente impacto sobre su estructura y funcionamiento. En este escenario, los bioensayos ecotoxicológicos se presentan como unas herramientas esenciales para la evaluación del riesgo de sustancias químicas y donde los peces debido a su posición trófica y valor ecológico son bioindicadores ideales. Los bioensayos con peces se basan en el desarrollo de biomarcadores sensibles y ecológicamente relevantes entre los que la natación es, posiblemente, la cualidad más básica sobre la que se sostienen todos los demás tipos de comportamiento. Cualquier alteración en el comportamiento de la natación puede reflejar cambios sobre niveles de organización ecológicamente relevantes...
This thesis is titled “Development and implementation of a miniaturized swimming flume to evaluate the swimming activity in growing stages of small fish models applied to ecotoxicological studies”.The progress of human society is largely due to the generation of a myriad of chemical substances, most of them irremediably end-up finding their way into continental aquatic bodies through different processes with consequent harm to ecosystems and humans. In this scenario, the ecotoxicological bioassays are essential tools for the ecological risk assessment of chemical substances and fish are effective bioindicators due to their trophic position and ecological role. Fish bioassays rely on the developmentof sensitive and ecologically relevant biomarkers and swimming is, arguably, the most basic and demanding quality upon which all other types of behavior are sustained. Any change in swimming behavior may reflect changes on ecologically relevant levels of organization. The importance of this type of biomarker lies in the existence of a large number of chemicals that exert -or are suspect of- neurobehavioral effects. To date, the vast majority of the investigations carried in this field with small fish models have relied on experimental set-ups generally consisting of static and constrained environments to which external artificial stimuli were applied...
