A decade ago, I was making my first steps in the field for Marine biology, passionate by the African manatee that I heard about for the first through an assignment essay during my Master program where I was asked to make a literature review of aquatic megafauna of Cameroon. It was not my favorite topic by then, and I was thrilled by emblematic animals like giraffe, lions, and elephants because they received higher media and public attention. However, as I dove into my assignment, I sadly realized that the aquatic megafauna species of Cameroon such as the African manatee were poorly known and seriously threatened by hunting for delicacy and accidental catch. The aesthetical value of our coastal waters and the magnificence of its biodiversity are hidden from the local public because they are underexplored. Like in most developing countries, marine research and exploration are scant because of the limited logistic and domestic skills. That was the same challenges my new passion for marine wildlife had to face. I use two main cost-effective strategies to get around those obstacles: (1) through using a participatory approach where fishermen use their smartphones and the SIREN mobile App to share pictures and information of opportunistic sighting of surfacing or accidentally captured marine wildlife on a publicly accessible webpage (http://siren.ammco.org/web/en/)..) (2) In areas with good enough water clarity, I am going to use an underwater technology like drone and hydroacoustics to explore life below the water surface, where many human eyes can't always reach, and then share the story of our exploration with the public.I worked with a team of young dedicated and enthusiastic marine scientists that I trained and who joined my project, and we are making this happy journey together. I will introduce my team member in my future posts. My team and I are preparing to launch our first underwater drone mission this coming January. This expedition will take place in the northern coast of Cameroon, offshore Limbe city. We are very curious to know what our drone will reveal. off course we will keep you posted, stay connected. Check out our the video below to learn about some of the other work will do when we are on the field.
