Using eDNA to detect marine megafauna in the Ibiza channel

21/02/2024

The Spatial Marine Lab is currently working with environmental DNA (eDNA), a novel non-invasive technique for marine megafauna monitoring. Through eDNA analysis of water samples, we can obtain species-specific presence data of marine megafauna and other organisms of interest. This method involves sequencing traces of DNA from shed cells, tissues, or mucus to identify the species inhabiting the sea without the need for visual observation.

Onboard the RV/SOCIB vessel, researchers from our group joined the CANALES campaigns to carry out eDNA sampling in the Ibiza Channel. For sample collection, we used the CTD (Conductivity, Temperature, and Depth) rosette equipped with 12 Niskin bottles to collect seawater at a depth of 5 m. The samples were then transported to the University of Valencia for filtration and sent to a specialized laboratory for sequencing.
