Since 2009, my research area aims at understanding the ecology of tropical diadromous fish, mainly by studying their dispersive marine stage. I have focused on 2 biological models, showing 2 characteristics of diadromy:
This first step of their life cycle conditions the success of the dispersive marine phase for this species that is widely distributed at the scale of the Indo-Pacific Ocean. The contact with sea water reveals to be obligatory for the pro-larvae pursue their life cycle and transform into marine larvae. This transition conditions the opening of the mouth and the anus, and so the first food intake, as well as the development of pectoral fins and eyes.
Through the supervision of a thesis, the recruitment of the juveniles (so called “bichiques”) of the 2 amphidromous goby species found in Reunion island (S. lagocephalus and Cotylopus acutipinnis) will be studied, with the aim of determine the recruitment abundance variability between the different rivers of the island, within the recruitment season, but also at an inter-annual scale. The differences in terms of sizes and ages of the bichiques recruiting between the different rivers will be analysed. Modelling oceanic larval dispersal before recruitment should allow explaining the trends that will be observed. In collaboration with the University of Reunion Island, we will lead a societal study focused on the bichiques fishery, the bichiques being an emblematic resource, strongly impacted by this traditional fishery.
