[Departement_IRSTEA]Eaux [TR1_IRSTEA]QUASARE International audience European eel (Anguilla anguilla) is a catadromous fish species that received substantial attention as its population has markedly declined in the last three decades. The possible causes of this decline include habitat fragmentation factors such as dams and weirs. In some cases, these obstacles are equipped with fish friendly passage devices that may select young eels according to their climbing behaviour. We tested how individual climbing tendency was related to the event of fishway passage experienced in the field and classified fish climbing profiles as climbing ‘leaders', ‘followers', ‘finishers' and ‘no climbers'. Moreover, we analysed the brain transcription level of genes related to neurogenesis and synaptic plasticity and compared it to climbing profiles.We found that fish from the upstream segments of an impounded river had a higher climbing propensity. Their behaviour was also more repeatable throughout the whole test than the obstacle-naive fish from the downstream segment. Moreover, we found that boldly climbing ‘leaders' had lower levels of transcription of synapse-related genes than the climbing ‘followers'. These differences could be related to coping styles of fish, where proactive ‘leaders' express a routine and risky behaviour, whereas reactive fish need an environmental assessment before exploratory behaviour. Our study showed that differences in climbing propensity exist in glass eelsseparated by water obstacles. Moreover, eels could adoptclimbing different strategies according to the way they dealwith environmental stress and to the cognitive abilities theypossess. |
