“…The description of the underwater marine soundscape by spearfishermen constitutes a contribution to LEK research by providing detailed observations on local processes impacting local fish distribution by water contamination and environmental changes, overfishing and climate change. This LEK can be integrated in academic research conducted on the Senegalese marine ecosystem in the form of working hypotheses and may contribute to the onset of an operational monitoring system of marine biodiversity based on underwater acoustics (Kammegne et al 2023). This article proposes an original method-the water-immersive approach-for the joint study of underwater ecology and the practices of a specific class of fishermen who involve their hearing combined with other senses in their activity.…”

At the crossroads of sensory anthropology and underwater bioacoustics, this article offers an immersive approach to garner the knowledge and perceptions of Dakar underwater fishermen. Four Senegalese fishermen conveyed their extensive knowledge of the peri-urban underwater environment through the descriptions of and commentaries on the seven dives they recorded using a camera equipped with an integrated microphone attached to their heads that focused on the marine soundscape. This methodology was aimed at documenting their ecological knowledge of the underwater marine environment of Dakar concerning its growth, the modifications of the shoreline, and underwater urban extensions such as sewers, water drainage from the surface and various discharges. Notions such as “guest” fish or “social” fish, among others, are used by divers to describe the behavior of fish, highlighting the elements that allow assessing the catchability of different species. A decrease in the attractiveness of the Dakar coast for migratory fish is described in connection with urban pollution discharges, the destruction of underwater habitats, and the development of scuba-diving and night-hunting practices. In general, the information collected puts into perspective the changes perceived both in connection with the worldwide scale of global warming and the problems of over-exploitation.

“…LEK provides a step forward for identifying fish sounds and associated fish behavior for bioacoustics monitoring of the marine environment (Ladich 2019(Ladich , 2022. This may contribute to the current development of underwater acoustic monitoring in Senegal (Kammegne et al 2023).…”
