Geographic variation in composition of metazoan parasite infracommunities in Galaxias maculatus Jenyns 1842 (Osmeriformes: Galaxiidae) in southern Chile (38-47° S)

open access: yesRevista Chilena de Historia Natural, 2020
Galaxias maculatus is an abundant freshwater fish species in Chilean continental waters where it plays important ecological functions, yet few parasitological records of this species exist in Chile and all of them cover a very limited geographic range ...

Global Patterns and Gaps in Research on Salinity Tolerance of Inland Fishes

open access: yesFish and Fisheries, Volume 27, Issue 2, Page 400-411, March 2026.
ABSTRACT Freshwater salinization is an emerging threat impacting approximately one‐third of the world's freshwater bodies. However, the salinity tolerance of many inland fishes remains understudied, despite being a crucial factor in determining species distributions and fitness.

Overwintering Fish Community in Ice‐Covered Environments in Hokkaido, Japan, Inferred From Environmental DNA

open access: yesEnvironmental DNA, Volume 7, Issue 2, March/April 2025.
Using fish eDNA metabarcoding, we successfully described an overwintering fish community in ice‐covered environments. eDNA data indicated that the dominant species were Clupea pallasii in the lagoon and Tribolodon spp. in the inlet river. Our findings suggested that the eDNA technique is useful for studying ice‐covered areas and could provide new ...

Design and Validation of an Open–Close Device for Integrated Environmental DNA Sampling Detects A Depth Gradient in Indian Ocean Deep‐Sea Fish Assemblages

open access: yesEcology and Evolution, Volume 15, Issue 2, February 2025.
The goal of this study was to leverage existing survey technology to design and test an eDNA sampler that captures an integrated eDNA sample over the length of a deep‐water transect. We provide a biological interpretation of the resulting data, demonstrating the usefulness of such technology to understand the ocean environments, using fish species as ...

A phylogenomic approach to reconstruct interrelationships of main clupeocephalan lineages with a critical discussion of morphological apomorphies

open access: yesBMC Evolutionary Biology, 2018
Background Previous molecular studies on the phylogeny and classification of clupeocephalan fishes revealed numerous new taxonomic entities. For re-analysing these taxa, we perform target gene capturing and subsequent next generation sequencing of ...

Allometric Growth and Condition Factors Throughout an Annual Life History of Landlocked Ayu Plecoglossus altivelis altivelis in Haidzuka Dam Reservoir

open access: yesLakes &Reservoirs, Volume 30, Issue 1, January/December 2025.
ABSTRACT Ayu Plecoglossus altivelis altivelis is a commercially and recreationally important freshwater fish in Japan. This species is categorised into two ecological forms: amphidromous migrating between rivers and sea and landlocked migrating between rivers and lakes or dam reservoirs. Despite its ecological and economical values, growth analysis has

Extreme Positive Selection on a New Highly-Expressed Larval Glycoprotein (LGP) Gene in Galaxias Fishes (Osmeriformes: Galaxiidae) [PDF]

open access: yesMolecular Biology and Evolution, 2010
We describe the intron-exon structure and DNA/protein sequences of a new larval glycoprotein (LGP) gene from nine species of galaxiid fish. The gene has a distant similarity to Danio THP (Tamm-Horsfall urinary glycoprotein; uromodulin) and cichlid SPP120 (seminal plasma glycoprotein) due to conserved features of its zona pellucida (ZP) domain ...

Fish Genomics and Its Application in Disease‐Resistance Breeding

open access: yesReviews in Aquaculture, Volume 17, Issue 1, January 2025.
ABSTRACT Global aquaculture production has been rising for several decades, with up to 76% of the total production from fish. However, the problem of fish diseases is becoming more and more prominent in today's context of pursuing sustainable aquaculture.
