Resumo(s)
In this paper we describe for the first time the occurrence of agonistic behaviour
in Chondrostoma polylepis (Pisces: Cyprinidae) in captivity. In this species agonistic behaviour
was present in adults of both sexes and juveniles, during spring and summer, well after the
end of the breeding season. Qualitative observations revealed the presence of a similar
pattern of agonistic behaviour in Chondrostoma duriensis. Despite intense observation effort,
no signs of agonistic behaviour were detected in three other Chondrostoma species of the
same geographical area, C. macrolepidotus, C. lemmingii and C. lusitanicum. It is hypothesized
that agonistic behaviour in C. polylepis and C. duriensis may be functionally linked to their
feeding ecology.
