Eugenol as anesthetic for Cnesterodon decemmaculatus (Cyprinodontiformes, Poeciliidae)

Laboratory Animals, 2023
Anesthetics are commonly used in fish for surgery and to facilitate capture, handling and transport in aquaculture and experimental procedures. In research, the selection of the anesthetic depends on its properties and on the recovery time. Eugenol has been pointed out as an effective anesthetic for fish, alternative to traditional drugs.

REPRODUCTIVE ADAPTATIONS AMONG VIVIPAROUS FISHES (CYPRINODONTIFORMES: POECILIIDAE)

Evolution; International Journal of Organic Evolution, 1978
Adaptations for placing a maximum number of mature offspring in the next generation fall between the two adaptive extremes of having either high reproductive rates and low survival rates or low reproductive rates and high survival rates. Among the fishes, both extremes have been realized; for example, the ling, Molva molva may produce 20-30 X 106 eggs ...

On the availability of the name Poecilia kempkesi Poeser 2013 (Cyprinodontiformes: Poeciliidae)

Zootaxa, 2021
The poeciliid species, Poecilia kempkesi Poeser, 2013, was the fourth species of the subgenus Acanthophacelus Eigenmann, 1907 to be described, based on individuals from a single urban anthropized locality close to Paramaribo, Suriname (Poeser, 2013).

Historical biogeography of aplocheiloid killifishes (Teleostei: Cyprinodontiformes)

open access: yesVertebrate Zoology, 2013
Aplocheiloid killifishes, a diversified group of primary freshwater fishes occurring in tropical and subtropical regions of the Americas, Africa and south-eastern Asia, have been the focus of debates among biogeographers using dispersal and vicariance approaches.

Molecular phylogeny of the livebearing Goodeidae (Cyprinodontiformes)

Molecular Phylogenetics and Evolution, 2004
The Goodeinae is a speciose group of viviparous freshwater fishes endemic to the Mesa Central of Mexico. The current taxonomy of the group is based on morphology associated with viviparity and several of the groupings are questionable. We sequenced part of the mitochondrial cytochrome c oxidase subunit I (COI) gene (627bp) and control region ...

Phylogeography of the genus Epiplatys (Aplocheiloidea: Cyprinodontiformes)

Molecular Phylogenetics and Evolution, 2009
There are six major genera of aplocheiloid killifishes endemic to West Africa. Five of these are largely restricted to the two major blocks of rainforest. Two are found within the Eastern rainforest block (Nigeria to the central Congo) while three are found within the Western rainforest block (Sierra Leone to Togo).

Osteological analysis of the killifish genusCynolebias (Cyprinodontiformes: Rivulidae)

Journal of Morphology, 1998
Relationships among the species of the annual fish Cynolebias are unclear. An analysis of the variation and utility of osteological characters for phylogenetic analysis was done using cleared and double-stained specimens representing 21 species of Cynolebias.

Evolution, ecology and physiology of amphibious killifishes (Cyprinodontiformes)

Journal of Fish Biology, 2015
The order Cyprinodontiformes contains an exceptional diversity of amphibious taxa, including at least 34 species from six families. These cyprinodontiforms often inhabit intertidal or ephemeral habitats characterized by low dissolved oxygen or otherwise poor water quality, conditions that have been hypothesized to drive the evolution of terrestriality.

Ultrastructural features of spermatogenesis in Melanorivulus punctatus (Cyprinodontiformes: Rivulidae)

Micron, 2014
Fish belonging to the family Rivulidae possess one of the most complex reproductive systems. Rivulus, a genus of freshwater fish in the Rivulidae family, was recently reclassified into five genera, including Melanorivulus. Its type species, M. punctatus, is widely distributed and probably represents a species complex.
