Immunocompetence and parasite infection in hybrids of roach (Rutilus rutilus) and common bream (Abramis brama)
Original language description
Hybrid heterosis may underlie the success of the hybrid vigour (measured for example as hybrid resistance against parasites). Nevertheless, hybridization may also disrupt the system of host-parasite gene co-adaptation. As the result, different parasite load in parental species and hybrids is expected. Hybrids with features inherited from both parental species may express different physiology and immunity when compared to those of their parental species. Consequently, it also affects parasite infection and the composition of parasite communities in the hybrid fish hosts. For this study, all metazoan parasites were collected from common bream (Abramis brama), roach (Rutilus rutilus) and their respective hybrids during spring and autumn 2011, 2012 and 2013. All fish specimens were identified using morphological traits and molecular markers (partial mitochondrial cyt b gene and 12 microsatellite loci). Basic physiological indexes were calculated to measure fish condition, vigour and immunocompetence.
