Decoding the complexities of the Dongjiang River basin fish community: Structure and functional traits using environmental DNA metabarcoding approaches

Heliyon
Fish play an important role in preserving global aquatic biodiversity and delivering ecosystem services. They are the focus of aquatic ecological research. Using environmental DNA (eDNA), we reported the diversity and structure of fish assemblages in the

Comparative Genomics of Lactococcus spp. From Global Aquaculture Outbreaks Reveals Virulence Determinants, Antibiotic Resistance, and Phage Defence Mechanisms

MicrobiologyOpen, Volume 14, Issue 6, December 2025.
Lactococcus petauri predominated in isolates from outbreaks of lactococcosis, suggesting a shift in disease aetiology. Genomic analysis revealed diverse virulence factors, prophage and resistance genes, while antimicrobial susceptibility testing showed uniform resistance to common antibiotics found in farming systems, emphasising the need for ...

Comparison of some traits of economic importance in tilapias (Orechromis niloticus and Sarotherodon galilaeus) with particular reference to their culture in Ghana [PDF]

, 2005
This study was conducted to determine which of the two major tilapia species in freshwater capture fisheries in Ghana, Oreochromis niloticus or Sarotherodon galilaeus, is more suitable for breed improvement and pond culture.

Phenotypical and Genomic Characterization of the Mollusk Pathogen Francisella halioticida

MicrobiologyOpen, Volume 14, Issue 6, December 2025.
Phenotypic and genetic characterization of French isolates of Francisella halioticida and comparison with Canadian and Japanese strains. The study revealed similarities between FR22s and previous isolates but distinct differences with FR21. A major finding is the absence of the Francisella pathogenicity island in the less virulent isolate, FR22b ...

Isolation and Identification of Pathogenic Bacteria Present in Commercially Important Fish, Shellfish, Water, and Soil Samples of Kaptai Lake, Bangladesh

Environmental Microbiology Reports, Volume 17, Issue 6, December 2025.
Soil, water, and fish samples were collected from 20 locations in Kaptai Lake to assess bacterial load and detect the presence of pathogenic bacteria. The results revealed a strong correlation among the samples and highlighted the need for actions to reduce microbial contamination in the lake. ABSTRACT This study aimed to analyse the enteric pathogenic

Analysis of morphometric and meristic characteristics of three cichlid species in central Iraq: farmed and wild

Oceanological and Hydrobiological Studies
This study is designed to assess morphological dissimilarities between aquaculture and feral groups of three cichlid fish species, Coptodon zillii (Gervais, 1848), Oreochromis aureus (Steindachner, 1864), and Oreochromis niloticus (Linnaeus, 1758). Feral

A Baseline of Fish Species Richness Through eDNA Metabarcoding in an Understudied Tropical Mangrove Coast of Java, Indonesia

Environmental DNA, Volume 7, Issue 6, November–December 2025.
This study demonstrates the use of environmental DNA metabarcoding of fish in a highly diverse but poorly described tropical mangrove ecosystem along the North coast of Java, Indonesia. Our results indicate eDNA metabarcoding can capture temporal differences and provide a baseline for fish diversity for future (eDNA metabarcoding) biodiversity studies ...
