Linkage Mapping vs. Association: A Comparison of Two RADseq‐Based Approaches to Identify Markers for Homomorphic Sex Chromosomes in Large Genomes

open access: yesMolecular Ecology Resources, Volume 25, Issue 7, October 2025.
ABSTRACT Reliable tools for the identification of genetic sex are invaluable in many fields of biology, but their design requires knowledge of sex‐linked sequences, which is lacking in many taxa. Restriction‐site‐associated DNA sequencing (RADseq) is widely used to identify sex‐linked markers, but multiple distinct strategies are employed, and it is ...

Bacterial 16S Ribosomal Gene Fingerprints as a Tool to Diagnose and Mitigate Fish Larvae Gut Dysbiosis

open access: yesEnvironmental Microbiology Reports, Volume 17, Issue 5, October 2025.
This study profiles the gut microbiota of poor‐ and good‐quality seabream and seabass larvae across different sites using 16S rRNA sequencing. Several bacterial markers associated with larval quality were identified and used to develop a dysbiosis index. Gut bacterial correlation networks revealed potential bacteria–bacteria interactions.

Fish Allergenicity Ladder and Parvalbumin Epitopes for Predicting Clinical Cross‐Reactivity and Reintroduction in Chinese Population

open access: yesAllergy, Volume 80, Issue 10, Page 2810-2823, October 2025.
Clinical history including self‐reported history and oral food challenge outcome, and sIgE sensitization profile of 200 subjects with suspected fish allergy was analyzed to construct a 3‐step fish allergenicity ladder. The allergenicity ladder was positively linked to the relative parvalbumin content of fish muscle but not to differences in the IgE ...

Parasites Are Paramount: Vertical Trophic Positions of Parasitic Catfishes in a Tropical River Food Web

open access: yesEcology of Freshwater Fish, Volume 34, Issue 4, October 2025.
ABSTRACT The Neotropical catfish family Trichomycteridae contains parasitic fishes that include scale and mucus feeders (subfamily Stegophilinae) and blood feeders (i.e., ‘candirus’, subfamily Vandelliinae). The influence of parasitic catfishes on food web dynamics is unknown.
