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

open access: yesMolecular 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.

Genomic Landscape of Divergence in Ballan Wrasse (Labrus bergylta)

open access: yesMolecular Ecology, EarlyView.
ABSTRACT The architecture underpinning genomic divergence is still a largely uncharted territory and likely case‐dependent. Here, we investigated genome‐wide variation in Ballan wrasse, a northeastern Atlantic fish species that displays two sympatric colour morphs, spotty and plain, that have been suggested to represent subspecies.

Hydrological Connectivity Enhances Fish Biodiversity in Amazonian Mining Ponds: Insights From eDNA and Traditional Sampling

open access: yesMolecular Ecology, EarlyView.
ABSTRACT Artisanal and small‐scale gold mining (ASGM) expansion in the Madre de Dios region of the Peruvian Amazon has transformed primary forests into a novel wetland complex of thousands of abandoned mining ponds. Despite their ecological relevance, post‐mining recovery of these systems remains understudied, particularly regarding fish biodiversity ...

Phylogenetic conservation of chromosome numbers in Actinopterygiian fishes. [PDF]

open access: yes, 2006
The genomes of ray-finned fishes (Actinopterygii) are well known for their evolutionary dynamism as reflected by drastic alterations in DNA content often via regional and whole-genome duplications, differential patterns of gene silencing or loss, shifts ...

Plectorhinchus macrolepis (Actinopterygii: Haemulidae) in the western Atlantic Ocean

open access: yesJournal of Fish Biology, 2019
AbstractMorphometric measurements, meristic counts and DNA barcoding identified the presence of a biglip grunt Plectorhinchus macrolepis in the western Atlantic Ocean. As the species is endemic to the tropical eastern Atlantic Ocean and has not previously been reported in the western Atlantic Ocean, we discuss the possible means by which it might have ...

Isolation, identification, and pathogenicity of γ‐hemolytic Streptococcus iniae in Selenotoca multifasciata

open access: yesJournal of the World Aquaculture Society, Volume 56, Issue 3, June 2025.
Abstract Streptococcus iniae is a fish pathogenic bacterium distributed worldwide. It has a wide range of hosts, strong infectivity, causes high mortality, and severely hinders the healthy development of the aquaculture industry. A fish epidemic broke out in a Selenotoca multifasciata aquaculture farm, Hainan Province, China, and resulted in numerous ...

Spawning Behavior in Hemitremia flammea (Actinopterygii: Cyprinidae)

open access: yesVirginia journal of science, 2001
Spawning behavior in Hemitremia flammea (Flame chub) is described from observations made in the field and laboratory. Spawning in the field occurred over clean gravel (size range=18-25 mm) at water temperatures from 12.8-14.4 C. Spawning in the laboratory occurred over clean gravel (11.3 mm) at water temperatures from 18.3-20 C.
