Resumo(s)
This study presents the first ethological description
of the reproductive behaviour of the cyprinid Squalius
pyrenaicus, endemic to the Iberian Peninsula. The behavioural
pattern of this endangered species during the breeding season
is non-communal and includes the preparation of a spawning
pit (depressions in the substratum) by males, a behaviour not
described for Iberian cyprinids so far but already reported for
North American cyprinids. The courting behaviour of males
displaying in spawning pits has a strong signalling component
towards females. Males from this species also showed agonistic
behaviours against other males, related with the defence
of their spawning pits. A positive association between male
dominance and courtship activity is discussed, as well as the
occurrence of sneaking by smaller and non-courting males.
The implications of the described reproductive behaviours for
the conservation and management of this endangered species
are addressed.
