Investigating otolith mass asymmetry in six benthic and pelagic fish species (Actinopterygii) from the Gulf of Tunis

open access: yesActa Ichthyologica et Piscatoria, 2021
Otolith mass asymmetry can significantly affect the vestibular system functionalities; usually, the X values of mass asymmetry vary between −0.2 and + 0.2 (−0.2 < X < + 0.2).

A new genus of coccolepidid fishes (Actinopterygii, Chondrostei) from the continental Jurassic of Patagonia [PDF]

open access: yesPalaeontologia Electronica, 2013
Jurassic freshwater fish faunas are still poorly known, with the only assemblage of that age known from southern South America being the "Almada fauna" of the Canadon Calcareo Formation (Oxfordian-Tithonian) of Chubut, Argentina. This fauna is composed mainly by abundant teleosts and a much rarer basal actinopterygian, originally described as ...

Phylogenetic Interrelationships of Ginglymodian Fishes (Actinopterygii: Neopterygii)

open access: yesPLoS ONE, 2012
The Ginglymodi is one of the most common, though poorly understood groups of neopterygians, which includes gars, macrosemiiforms, and "semionotiforms." In particular, the phylogenetic relationships between the widely distributed "semionotiforms," and between them and other ginglymodians have been enigmatic.

Fish hatchering and its effects on the morphology of Prochilodus lineatus (Actinopterygii: Prochilodontidae) [PDF]

open access: yesBrazilian Journal of Biology, 2016
Abstract The fish stocking in captivity for later release into natural water bodies has historically been applied in Brazil, as a measure to mitigate impacts caused by dams. However, the released fish are adapted to the hatchery environment, which is totally different from the natural, which results in low post-release survival rates and ...

Update to the catalogue of South Australian freshwater fishes (Petromyzontida &amp; Actinopterygii) [PDF]

open access: yesZootaxa, 2012
South Australia is a large Australian state (~1,000,000 km2) with diverse aquatic habitats spread across temperate to arid environments. The knowledge of freshwater fishes in this jurisdiction has advanced considerably since the last detailed catalogue of native and alien species was published in 2004 owing to significant survey and research effort ...

Integrating multi-origin expression data improves the resolution of deep phylogeny of ray-finned fish (Actinopterygii)

open access: yesScientific Reports, 2012
The actinopterygians comprise nearly one-half of all extant vertebrate species and are very important for human well-being. However, the phylogenetic relationships among certain groups within the actinopterygians are still uncertain and debates about ...

Evaluating the size at sexual maturity for 20 fish species (Actinopterygii) in wetland (Gajner Beel) ecosystem, north-western Bangladesh through multi-model approach: A key for sound management

open access: yes, 2021
Effective fisheries management depend on having an exact assessment of biological parameters, including growth parameters, reproduction, size at sexual maturity (Lm), and stock assessment.

Length–weight relations of 14 fish species (Actinopterygii) from the Chalakudy River, Western Ghats, India

open access: yesActa Ichthyologica et Piscatoria, 2021
Length–weight relations of 14 fish species caught by small-scale fishery from the Chalakudy River of the Western Ghats biodiversity hotspot, India were analyzed from April 2018 to March 2019.

Comprehensive phylogeny of ray-finned fishes (Actinopterygii) based on transcriptomic and genomic data [PDF]

open access: yesProceedings of the National Academy of Sciences, 2018
Significance Ray-finned fishes form the largest and most diverse group of vertebrates. Establishing their phylogenetic relationships is a critical step to explaining their diversity. We compiled the largest comparative genomic database of fishes that provides genome-scale support for previous phylogenetic results and used it to resolve ...
