Satellite tagging of European sturgeon Acipenser sturio

Marquage satellites d'esturgeons européens Acipenser sturio


European sturgeon migration between the estuary environment and the sea as well as its behaviour at sea are little-known. This experimentation intend to follow its movement at large scale and to identify the characteristics of the environment use, mainly temperature and depth. For this purpose, since we focus on large individuals, pop-up satellite archival tags (PSATs) offer the following advantages (1) gathering complementary and independent data from incidental observations and (2) recovering the data with no need to capture the fish since the detachment is programmed. Following Sequeira et al. (2019), for this type of tagging, a sample of 10 individuals is rational for critically endangered species. Individual information have high value and this number would allow to assess individual variability and to generate first hypothesis on migratory behavior. It is also a starting point to evaluate if the method gives the expected quality of data
