Projet scientifique POPSIZE : Approche alternative de l’estimation de l’abondance des populations exploitées utilisant la génétique (2020-2023). FEAMP. Scientific Report. pp.1-344 ; Regional Fisheries Management Organizations (RFMOs) advocate the application of multiple complementary methods for sustainable management and assessment of the health status of commercially exploited large pelagic stocks, such as tuna, marlins, and bonitos, or bycatches like sharks and marine mammals. The Indian Ocean Tuna Commission (IOTC), the International Commission for the Conservation of Atlantic Tunas (ICCAT), and the Commission for the Conservation of Southern Bluefin Tuna (CCSBT) have endorsed the value of studying intraspecific genetic variability within stocks to better understand their spatiotemporal distribution, adaptive capacity, and current and historical abundance. Such information facilitates concrete applications in terms of conservation, such as considering genetically distinct subgroups as separate management units or detecting risks of genetic diversity erosion over varying time scales for a given species and/or geographical region.Scientific programs focused on albacore tuna (Thunnus alalunga), a commercially important temperate tuna species, and blue shark (Prionace glauca), a top predator significantly impacted from bycatches, have yielded global-scale genetic variability data for these two species. The most recent programs have leveraged advanced DNA sequencing technologies, known as "genomic scans," enabling the characterization of intraspecific genetic variability with high genome-wide resolution across numerous individuals using small tissue samples (skin, fin, muscle). These technologies have unlocked numerous avenues for studying genetic diversity, ... |
