Diet composition of a native fish species in a neotropical lentic environment
Acta Scientiarum: Biological Sciences, 2023 Native species are important to the dynamics of aquatic environments. Studies that seek to understand the basic biology of these species provide information on the species and the dynamics of the natural environment.

A Hiatus Obscures the Early Evolution of Modern Lineages of Bony Fishes
Frontiers in Earth Science, 2021 About half of all vertebrate species today are ray-finned fishes (Actinopterygii), and nearly all of them belong to the Neopterygii (modern ray-fins). The oldest unequivocal neopterygian fossils are known from the Early Triassic.

Evidence for reproductive senescence across ray-finned fishes: A review
Frontiers in Ecology and Evolution, 2022 The origin, incidence, and consequences of reproductive senescence vary greatly across the tree of life. In vertebrates, research on reproductive senescence has been mainly focused on mammals and birds, demonstrating that its variation is largely linked ...

Absolute 3D Pose Estimation and Length Measurement of Severely Deformed Fish from Monocular Videos in Longline Fishing [PDF]
arXiv, 2021 Monocular absolute 3D fish pose estimation allows for efficient fish length measurement in the longline fisheries, where fishes are under severe deformation during the catching process. This task is challenging since it requires locating absolute 3D fish keypoints based on a short monocular video clip.

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

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

Fake Hilsa Fish Detection Using Machine Vision [PDF]
, 2022 Hilsa is the national fish of Bangladesh. Bangladesh is earning a lot of foreign currency by exporting this fish. Unfortunately, in recent days, some unscrupulous businessmen are selling fake Hilsa fishes to gain profit. The Sardines and Sardinella are the most sold in the market as Hilsa.

Phylogenetic Interrelationships of Ginglymodian Fishes (Actinopterygii: Neopterygii)
PLoS 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.
