Fish Physiology and Biochemistry, 2015
Sperm quality tests on fish are classically used for evaluating cryopreservation procedures, and they are also promising to assess aquatic toxicity and biomarkers of xenobiotic effects on reproduction. Osmotic shock from the storage medium is one of the main factors affecting sperm quality during evaluation.

Molecular systematics of the genus Allodontichthys (Cyprinodontiformes: Goodeidae)
Reviews in Fish Biology and Fisheries, 2002Phylogenetic analyses of cytochrome c oxidasesubunit I (627bp) and mitochondrial controlregion (338bp aligned) sequences for all knownspecies of Allodontichthys wereperformed. Allodontichthys was recoveredas monophyletic, and A. hubbsi wassupported as the most primitive member of thegenus in all analyses. Combined-data analysessuggest that A. polylepis

The gonopodia of the fishes of the tribe Cnesterodontini (Cyprinodontiformes, Poeciliidae)
Journal of Fish Biology, 1990The South American livebearing toothcarp tribe Cnesterodontini is discussed, and a description of the gonopodium of each of the species of the four genera is given, together with a figure and a synonymy.

Studies on the Blood Morphology of Three Estuarine Cyprinodontiform Fishes
Journal of the Fisheries Research Board of Canada, 1969Specimens of Fundulus heteroditus, Fundulus majalis, and Cyprinodon variegatus were bled in the field at the site of capture. Blood was obtained during all seasons and in the laboratory at intervals over a 30-day period from specimens held in two types of holding aquaria.
