Morphometric synthesis of Pollimyrus (Teleostei, Mormyridae) with the description of four new species

Journal of Fish Biology, Volume 106, Issue 3, Page 846-892, March 2025.
Abstract Mormyridae, a species‐rich family endemic to Africa, remains taxonomically understudied. This has been the case for the genus Pollimyrus Taverne, 1971, which hinders further understanding of the distribution, ecology, and conservation of its species.

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 ...

Backward swimming in elongated‐bodied abyssal demersal fishes: Synaphobranchidae, Macrouridae, and Ophidiidae

Journal of Fish Biology, EarlyView.
Abstract The deep‐sea demersal fish fauna is characterized by a prevalence of elongated‐body forms with long tapering tails. Using baited camera landers at depths of 4500–6300 m in the Pacific Ocean, we observed multiple instances of backward swimming using reverse undulation of the slender body in four species: the cutthroat eel Ilyophis robinsae ...

Morphological and metabarcoding dietary analysis of the cunner wrasse (Tautogolabrus adspersus) revealed significant regional variation, with large overlap between its common prey species and biofouling animals living on salmonid sea cages

Journal of Fish Biology, EarlyView.
Abstract The stomach‐less cunner wrasse (Tautogolabrus adspersus) has been experimentally used as a biological control agent for salmon lice that infest Atlantic salmon (Salmo salar) and to remove biofouling inside sea cages. The cunner demonstrates a strong population structure, suggesting that its diet, and therefore its usefulness for biological ...

The first draft genome assembly and data analysis of the Malaysian mahseer (Tor tambroides)

Aquaculture and Fisheries, 2023
The Malaysian mahseer (Tor tambroides), one of the most valuable freshwater fish in the world, is mainly targeted for human consumption. The mitogenomic data of this species is available to date, but the genomic information is still lacking.

Aquatic eDNA outperforms sedimentary eDNA for the detection of estuarine fish communities in subtropical coastal vegetated ecosystems

Journal of Fish Biology, EarlyView.
Abstract In South Africa, mangrove forests and seagrass meadows often co‐occur in estuarine systems and in combination host rich, often endemic biodiversity. There is an urgent need to explore community diversity in coastal vegetated ecosystems, given the degrading effects of climate change and anthropogenic pressures.

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

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 ...

Genomic insights on conservation priorities for North Sea houting and European lake whitefish (Coregonus spp.)

Molecular Ecology, EarlyView.
Abstract Population genomics analysis holds great potential for informing conservation of endangered populations. We focused on a controversial case of European whitefish (Coregonus spp.) populations. The endangered North Sea houting is the only coregonid fish that tolerates oceanic salinities and was previously considered a species (C.
