Identification des flux de civelles (Anguilla anguilla) à partir des relations d'allométrie en fonction des conditions hydrodynamiques de l'estuaire de l'AdourIdentification of glass eels groups (Anguilla anguilla) from variability of allometry relations according to hydrodynamics conditions in the Adour estuary.

A model for the upstream motion of elvers in the Adour River

“…We give below some details and conclusions of the studies by de Casamajor et al [3][4][5][6]. The region studied was 20 km long, and the data were collected by 5 experimental stations.…”

“…Several studies [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22] have already described the entrance of elvers in the 'Adour' estuary and the mi-gration phenomenon details. De Casamajor et al [3][4][5][6] also evaluate the stocks of elvers in different years and seasons.…”

De Casamajor et al [3][4][5][6] also evaluate the stocks of elvers in different years and seasons. These works have required an interdisciplinary collaboration of mathematicians, physicists, and biologists, as a consequence of the amount and different type of factors involved in eels evolution and modelling.…”

“…The studies by de Casamajor [3][4][5][6] focused on biological and physical aspects. Firstly, they carried out the identification of different groups of elvers by analyzing individual allometric features, size, weight, pigmentation and otoliths development.…”

“…Pardo et al The works by de Casamajor et al [3][4][5][6] and Pardo et al [7] are complementary and have given many answers. However, some questions remain: how do individual elvers choose the depth they will swim at?…”
