To show the negative effects of goldfish on native amphibians we want to
make experimental studies and field studies in Austria. Direct and
indirect effects of goldfish, like predation or growth of the tadpoles,
will be recorded.
Has anyone experience in this topic, especially laboratory methods and
intestine analyses of goldfish or other Cyprinidae?
