Sexual ornamentation and parasite infection in males of common bream (Abramis brama): a reflection of immunocompetence status or simple cost of reproduction?

Original language description

Abstract: Question: How does sexual ornamentation relate to parasite infection, host immune response and somatic condition status in male fish? Hypotheses: Zahavi's (1975) handicap hypothesis proposes that producing secondary sexual traits represents a considerable handicap for males. Additionally, Hamilton and Zuk (1982) proposed that the expression of secondary sexual traits reveals a genetic resistance against parasites. Organisms: Spawning males of common bream (Abramis brama) and several of its parasites (Gyrodactylus spp., Diplostomum spp., Argulus spp.). Variables: Parasite abundance (for parasite infection), spleen size (for host immune response) and condition (for somatic condition status). Results: The more tubercles on the fish, the more abundant the Gyrodactylus spp. The more tubercles on the fish's head, the more abundant the Diplostomum spp. The greater the mean length of the head tubercles, the more abundant the Gyrodactylus spp. and Argulus spp. However, we found no rel
