16S and 18S V4 rRNA metabarcoding sequencing of bacterial, archaeal, and eukaryote communities in benthic sediment sampled along a geographical gradient around a shrimp farm (Toahotu lagoon, French Polynesia) for the DEPOMOD-shrimp project, 2020-2024

This work aims at describing benthic bacterial, archaeal, and metazoan communities along a geographical gradient to assess the effects of a shrimp farm (releasing organic matter such as uneaten feed and faecal pellets) on these communities. The samples were collected in several benthic stations from 0 m to 200 m from the farm cages, as well as in another station located several kilometers from the study area. This study includes two datasets: one based on 16S rRNA gene sequencing, which characterizes the bacterial and archaeal communities, and the other based on 18S rRNA gene sequencing, which describes the metazoan communities.
