The effects of larval cestode (Neogryporhynchus cheilancristrotus) infection on the reproduction of golden venus chub Hemigrammocypris neglectus and their population growth were estimated by analysis of the relationships between the abundance of cestodes and the breeding behavior of male chubs, as well as the fecundity of female chubs. N. cheilancristrotus causes a prominent abdominal distention in H. neglectus because of a hypertrophied hepatopancreas. Cestode infection displayed no negative relationship to chasing behavior by males of females or to the number of prenatal eggs in females. Thus, we conclude that cestode infection has little effect on the population growth of the host fish through reproductive behavior/fecundity, despite the prominent pathological change in the hepatopancreas.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
