Resumo(s)
In this paper we describe, for the first time, the reproductive behaviour of the
rare Iberian cyprinid fish Chondrostoma lusitanicum, endemic to Portugal. The species is an egg
broadcaster releasing adhesive eggs. Spawning aggregations may involve large numbers of
fish but within a group, short sequences of courtship and spawning typically involve one
female and one or a few males. Males follow females touching them frequently and at spawning
press the female body against the available objects. Males perform circles that may help to
retain a female in a given area. A special behaviour is described for females with the likely
function of attracting males and initiating courtship.
