At just 27, Sarobidy Rakotonjatovo combines science, entrepreneurship, and the valorization of marine resources. She is the founder of Menatsook, a young SME that aims to give a new life to sea urchins. Through her journey, this young researcher also wants to send a message to young people: never stop learning.
What studies did you pursue to lead a company at only 27?
I am a marine science engineer, a graduate of the Institute of Fisheries and Marine Sciences (IHSM) in Toliara. I followed the biotechnology path, which focuses on research and resource transformation. It was during my research that the idea of working on sea urchins began to emerge. I wondered why these marine animals should only be destined to become the famous “sea urchin cakes” sold on the streets of Toliara. I thought it was possible to value this marine resource differently. That’s how Menatsook was born earlier this year. The name combines “menaka,” which means oil, and “sook,” derived from “souky,” the local name for the sea urchin cake.
Concretely, which part of the sea urchin do you exploit?
I exploit the sea urchin in all its forms! Menatsook’s goal is to give a new life to the different parts of the sea urchin. We recover the oil to develop cosmetic products, such as shampoos, masks, and hair creams. This oil can also be used in food. As for the shells, they are transformed into decorative objects and fashion accessories.
Does this exploitation risk disrupting the balance of marine biodiversity?
Menatsook currently buys about 10 kilos of sea urchins per week from coastal women’s communities. We are still at a relatively limited quantity. Beyond the economic aspect, my approach is linked to my research on finding a balance within the marine ecosystem. In the Southwest, sea urchin density can be three to five times higher than normal due to ecosystem changes. When natural predators decrease, their population can increase excessively, which can weaken corals. The goal is not to exploit them to extinction, but to find a balance between economic valorization and ecosystem preservation.
You were also selected for the IORA ECOP program in Australia. What is it about?
It is an eight-week scientific immersion in Australia. This experience is a real opportunity to deepen the innovative project led by Menatsook, particularly through the “Blue Carbon” concept, studying the link between sea urchin harvesting, seagrass restoration, and carbon storage capacity.
What message do you want to convey to young people?
My first message is simple: never get tired of learning. The knowledge we acquire must allow us to develop our ability to think and, above all, to find solutions to the problems around us. It is also essential to remain faithful to one’s life goal, despite the difficulties and failures that may mark our path.
