Abstract(s)
During the spring of 2022, several endangered leuciscid species (Anaecypris hispanica, Squalius aradensis, Anachondrostoma Occidentale, and
Iberochondrostoma lusitanicum) were sampled both
at the Vasco da Gama aquarium facilities and in some
rivers of the Algarve region, Portugal. Sperm samples were extracted by gentle abdominal pressure and
sperm motion parameters were assessed for the frst
time in four species, using a computerized analysis
system. The results obtained showed that spermatozoa kinetic patterns were similar for all 4 species,
with high motility and velocity values after the sperm
activation time and with a marked decrease after 20.
On the other hand, sperm longevity was highly variable between species, with short longevities (around
40 s) for A. hispanica and S. aradensis, and longer ex situ breeding programs that are being developed
for these four endangered species
