Research
Current research topics
Since the 1970s, a significant decline in the abundance of salmon populations has been observed. This decline has been accompanied by the decrease in the average age at maturity and the size of fish returning to rivers to spawn. This steep decline and these changes in life history traits seem to be the result of an ecosystem modification during their marine phase. My current research aims to understand the link between these life history traits and both biotic and abiotic parameters experienced by salmons during their marine migration, in particular the hypothesis of a modification of their diet. The study of data from historical salmon collections (scales and isotopes) from 5 populations in the Channel area (Frome, Tamar, Bresle, Selune and Scorff) over more than 30 years would allow to lift the veil on such changes.
