The Impacts of Pregnancy on Cognition and Cell Proliferation in a Live‐Bearing Fish (Poeciliopsis gracilis)

European Journal of Neuroscience, Volume 63, Issue 9, May 2026.
We assessed the impact of pregnancy on cognition and cell proliferation in the live‐bearing fish Poeciliopsis gracilis. Pregnant females showed reduced spatial learning but unchanged reversal learning, alongside decreased cell proliferation in the olfactory bulb and ventral telencephalon, indicating pregnancy‐induced cognitive and neural changes in a ...

Aspects of the Histopathology of Clarias gariepinus Infected With the Camallanid Parasite Procamallanus (Procamallanus) pseudolaeviconchus Moravec and Van As, 2015

Journal of Fish Diseases, Volume 49, Issue 5, May 2026.
ABSTRACT Histopathological studies of infections with the nematode Procamallanus (Procamallanus) pseudolaeviconchus Moravec and Van As, 2015, an intestinal parasite of Clarias gariepinus (Burchell, 1822), are scarce. The current study describes histopathological changes in the stomach of C. gariepinus infected with P.

Opsin expression predicts male nuptial color in threespine stickleback. [PDF]

, 2018
Theoretical models of sexual selection suggest that male courtship signals can evolve through the build-up of genetic correlations between the male signal and female preference.

Kin Recognition in a Clonal Fish,Poecilia Formosa

PLOS ONE, 2016
AbstractRelatedness strongly influences social behaviors in a wide variety of species. For most species, the highest typical degree of relatedness is between full siblings with 50% shared genes. However, this is poorly understood in species with unusually high relatedness between individuals: clonal organisms. Although there has been some investigation
