“…However, such scenario would imply the frequency distribution of a hypothetical sea lamprey parasite to co‐vary with an abundance of sea lamprey hosts (here investigated) across spatial scales. As in the case of sea lamprey being the parasite, data on sea lamprey's parasites is scarce and the functional link to fitness remains elusive (Shavalier et al, 2021 ).…”

Sea lamprey Petromyzon marinus is an anadromous and semelparous fish without homing behaviors. Despite being a freshwater, free‐living organism for a large part of their life cycle, its adulthood is spent as a parasite of marine vertebrates. In their native European range, while it is well‐established that sea lampreys comprise a single nearly‐panmictic population, few studies have further explored the evolutionary history of natural populations. Here, we performed the first genome‐wide characterization of sea lamprey's genetic diversity in their European natural range. The objectives were to investigate the connectivity among river basins and explore evolutionary processes mediating dispersal during the marine phase, with the sequencing of 186 individuals from 8 locations spanning the North Eastern Atlantic coast and the North Sea with double‐digest RAD‐sequencing, obtaining a total of 30,910 bi‐allelic SNPs. Population genetic analyses reinforced the existence of a single metapopulation encompassing freshwater spawning sites within the North Eastern Atlantic and the North Sea, though the prevalence of private alleles at northern latitudes suggested some limits to the species' dispersal. Seascape genomics suggested a scenario where oxygen concentration and river runoffs impose spatially varying selection across their distribution range. Exploring associations with the abundance of potential hosts further suggested that hake and cod could also impose selective pressures, although the nature of such putative biotic interactions was unresolved. Overall, the identification of adaptive seascapes in a panmictic anadromous species could contribute to conservation practices by providing information for restoration activities to mitigate local extinctions on freshwater sites.

Sea lamprey Petromyzon marinus is an anadromous and semelparous fish without homing behaviours. Despite being a freshwater, free-living organism for large part of its life cycle, its adulthood is spent as a parasite of marine vertebrates. Here, we performed the first genome-wide characterization of sea lamprey genetic diversity in their European natural range. The objectives were to investigate the connectivity among river basins and explore evolutionary processes mediating dispersal during the marine phase. For that, we sequenced 186 individuals from 8 locations spanning the North-eastern Atlantic coast and the North Sea with double-digest RAD-sequencing, obtaining a total of 30910 bi-allelic SNPs. Population genomic analyses reinforced the existence of a single metapopulation encompassing freshwater spawning sites within the north-eastern Atlantic and the North Sea, though the prevalence of private alleles at northern latitudes suggested some limits to the species dispersal. Seascape analyses revealed candidate loci associated with the abundance of some host species and were located in a genomic region coding for variable lymphocyte receptors, an adaptive immunity tool unique to jawless vertebrates, and to MARCH proteins, a family of E3 ubiquitin ligases also involved in the regulation of immune responses. Abiotic factors (e.g., maximum phosphate, dissolved oxygen and water temperature) were significantly correlated with candidate loci associated with the myo-inositol synthesis, a pathway linked to osmoregulation, and to other genomic regions involved in organismal homeostasis. The identification of adaptive seascapes in this ancient species, especially if linked to primitive adaptive immune responses, could be relevant to understand the evolutionary pathways early in vertebrate evolution.

Parasites are very diverse and common in both natural populations and in stocks kept in aquacultural facilities. For most cultured species, there are important bacteria and viruses causing diseases, but eukaryotic parasites are also very important. We review the various combinations of aquacultured species and eukaryotic parasitic groups and discuss other problems associated with aquaculture such as eutrophication, zoonotic species, and invasive species, and we conclude that further development of aquaculture in a sustainable manner must include a holistic approach (One Health) where many factors (e.g., human health, food safety, animal health and welfare, environmental and biodiversity protection and marketability mechanisms, etc.) are considered.
