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 ...

Trap‐dependence in capture–recapture studies: empirical evidence in vertebrates and biological meaning

Oikos, Volume 2026, Issue 2, February 2026.
Capture–recapture (CR) models have been used for decades to estimate population size and demographic rates in natural populations from the monitoring of individuals. One of the most frequent deviations from assumptions required in CR studies is the immediate trap‐dependence that corresponds to the correlation between capture events. We review empirical

Environmental DNA highlights fish biodiversity in mesophotic ecosystems

Environmental DNA, 2023
Mesophotic marine ecosystems are characterized by lower light penetration supporting specialized fish fauna. Due to their depths (−30–−150 m), accessibility is challenging, and the structure of mesophotic fish assemblages is generally less known than ...

Indigenous peoples and local community reports of climate change impacts on biodiversity

Conservation Biology, Volume 40, Issue 1, February 2026.
Abstract Climate change impacts on biodiversity have been primarily studied through ecological research methods, largely ignoring other knowledge systems. Indigenous and local knowledge systems include rich observations of changes in biodiversity that can inform climate change adaptation planning and environmental stewardship.

Serum amyloid A is a positive acute phase protein in Russian sturgeon challenged with Aeromonas hydrophila

Scientific Reports, 2020
The immune system of sturgeons, one of the most ancient and economically valuable fish worldwide, is poorly understood. The lack of molecular tools and data about infection biomarkers hinders the possibility to monitor sturgeon health during farming and ...

Endoskeletal structure inCheirolepis(Osteichthyes,Actinopterygii), An early ray‐finned fish [PDF]

Palaeontology, 2015
AbstractAs the sister lineage of all other actinopterygians, theMiddle toLateDevonian (Eifelian–Frasnian)Cheirolepisoccupies a pivotal position in vertebrate phylogeny. Although the dermal skeleton of this taxon has been exhaustively described, very little of its endoskeleton is known, leaving questions of neurocranial and fin evolution in early ray ...

Unveiling Vertebrate Biodiversity in Arid and Semi‐Arid Terrestrial Ecosystems Through eDNA Metabarcoding at Savanna Waterholes

Evolutionary Applications, Volume 19, Issue 2, February 2026.
ABSTRACT Applying environmental DNA (eDNA) metabarcoding to samples from waterholes and their surroundings offers a promising approach for monitoring terrestrial vertebrates in semi‐arid and arid ecosystems, such as the southern African savannas. However, minimal guidance exists on key sampling design parameters for terrestrial ecosystems, which can ...

Orthopristis chrysoptera (Actinopterygii: Perciformes: Haemulidae): A new alien fish for the Mediterranean Sea

Acta Ichthyologica et Piscatoria, 2020
An individual of Pigfish, Orthopristis chrysoptera (Linnaeus, 1766), is recorded for the first time for the Mediterranean Sea, raising to six the number of species of the family Haemulidae in the basin. The fish was caught on 12 September 2020 in the harbor of Siracusa (Ionian Sea) by an angler and had an estimated total length of about 16 cm. Possible

Chromosome evolution in fishes: a new challenging proposal from Neotropical species

Neotropical Ichthyology
We present a database containing cytogenetic data of Neotropical actinopterygian fishes from Venezuela obtained in a single laboratory for the first time. The results of this study include 103 species belonging to 74 genera assigned to 45 families and 17
