Parasite pathogens in new species of Mediterranean aquaculture: an experimental approach

Objetivo

Species diversification has become a major challenge to Mediterranean aquaculture. The greater amberjack Seriola dumerili is one of the "new species" of interest for diversification. However, the development of greater amberjack farming at industrial scale is jeopardized by several highly pathogenic parasites. Gill monogeneans (Heteraxinidae) and blood flukes (Sanguinicolidae) are known to cause mass mortalities in experimental amberjack cultures. The control of these infections is hampered by the lack of knowledge about the biology of these parasites. This project will attempt to elucidate the life cycle of heteraxinid monogeneans and sanguinicolid blood flukes infecting cultured greater amberjacks, as well as to evaluate different strategies to control the infections caused by these parasites. The project includes three aspects: First, a taxonomical study of the parasites, second, a study of the development, transmission and life cycle (including the development of free living and parasitic stages and the habitat selection within the fish) and, third, an evaluation of several prophylactic and control methods (including several substances commonly used in fish cultures, such as disinfectants and anaesthetics). The results of this project will allow to ascertain the life cycle and transmission of heteraxinid and sanguinicolid parasites infecting the greater amberjack in fish farms and will suggest prophylactic and treatment methods for future application in intensive aquaculture facilities of the fish species. It is expected that this new information will serve to develop control policies, not only for aquaculture of the greater amberjack, but also for that of similar species, thus contributing to the development and diversification of Mediterranean fish farming in EU member states.
