Relationships between locomotor behavior, morphometric characters and thyroid hormone levels give evidence of stage-dependent mechanisms in European eel upstream migration
[Departement_IRSTEA]MA [TR1_IRSTEA]QSA / DYMECO International audience In order to decipher movements during freshwater eel colonization, we experimentally characterized individual locomotor behavior of two eel life history stages: elvers and yellow eels.

[Departement_IRSTEA]MA [TR1_IRSTEA]QSA / DYMECO International audience In order to decipher movements during freshwater eel colonization, we experimentally characterized individual locomotor behavior of two eel life history stages: elvers and yellow eels.
