This study aims to compare different metabarcoding sequences of commercially fished shrimps collected by tree counties on the North Brazil Shelf Large Marine Ecosystem

Genetic diversity is often considered a key factor in a species’ ability to adapt to environmental changes and our aim was to understand the biological, ecological, and biogeographic factors that explain differences in genetic diversity among marine fish. Therefore, whole genomes of 160 individual marine fish were sequenced to a minimum depth of 15×, enabling near-complete representation of each diploid genome.

Sequenced samples are city center wastewater sampled by passive samplers. Variants are identified by Illumina Miseq sequencing.

Comparison between 3 kits, Roche, Twist Biosciences and Illumina on the ability to enrich environmental samples to viral sequences. 5 sewage samples were extracted in triplicats with selective extraction protocol.

Develop parentage assignment panels using genetic fingerprinting of pearl oysters for use in commercial hatcheries and research to manage pedigrees in order to limit the risks of loss of genetic variability and increased inbreeding of commercial lines.

This study gathers multi-year environmental sequencing datasets generated within the French ROME pilot observatory network. It includes eDNA metabarcoding and RNA-based analyses from water samples, oyster tissues, and viral fractions collected across four French estuarine ecosystems between 2020 and 2023, supporting integrated monitoring of coastal microbiomes and microbial hazards.

Raw reads for the assembly of Gambusia holbrooki genome.

scRNA-seq reads from a Pacific oyster (Crassostrea gigas) hemocyte preparation. Hemocytes were isolated from a unique immunologically naive animal (Ifremer Standardized Animal, 18 months) and single-cell drop-seq technology was applied to 3,000 individual hemocytes.

Vibrio bacteria sampled from juvenile oysters and seawater collected in Thau Lagoon (Languedoc-Roussillon, France) in October 2015 during a mortality event were genotyped using hsp60, rctB, topA and mreB protein-coding genes
