• Resumen

  • This PhD thesis evaluates the links between parasitism, condition and reproduction of mature female individuals of three of the most captured fish species in the western Mediterranean Sea: European hake, Merluccius merluccius; red mullet, Mullus barbatus, and European anchovy, Engraulis encrasicolus. Indicators of fish energy reserves (total lipid content in liver, muscle and gonads) and reproductive capacity (fecundity and egg quality) were evaluated, as were the prevalence and intensity of infection by metazoan parasites. By evaluating these relationships, this thesis also provides essential data on the health and reproduction of these three fish species, such as the spawning strategy.
