Description du projet
Un nouveau système de détection et d’évaluation de la biodiversité marine
La préservation de la biodiversité des océans est devenue de plus en plus essentielle dans un contexte de changement climatique. Le secteur de la pêche doit faire face à la nécessité de s’adapter à ces changements tout en respectant les quotas. Toutefois, cette tâche est entravée par l’absence d’aide et d’innovation, en particulier pour les grandes opérations de pêche. Face à cette problématique, le projet SYMBIOSIS, financé par l’UE, propose une solution permettant une transition plus aisée vers un secteur de la pêche plus durable. La clé réside dans un système de surveillance équipé de capteurs acoustiques et optiques, qui permet aux pêcheries d’identifier, d’évaluer et de localiser des espèces de poissons spécifiques. Les données obtenues permettront aux utilisateurs de prendre des décisions éclairées et d’éviter de pêcher des espèces menacées de façon gérable.
Objectif
We present the SYMBIOSIS project to provide a mature, cost effective autonomous optco-acoustic prototype for the characterization, classification, and biomass evaluation of six target pelagic fish that are important to the fishery industry and that reflect on the health of the environment. The processing will be made in a real-time fashion onsite, and the results will be sent to a shore station. The system will be completely autonomous and will withstand three month deployment without recharging. We will demonstrate the capabilities of the system and its readiness to a TRL6 stage over three sea and ocean mooring sites.
SYMBIOSIS is devised as a blend of acoustic and optical components. The acoustic unit will include an active underwater acoustic array of 2X3 elements, to detect, classify, evaluate the biomass, and localize the predefined pelagic fish in the far field of 500m. The optical component will comprise of a fixed frame of six underwater optical cameras, and will perform machine learning-based classification and biomass evaluation in the near field of 2-3 attenuation lengths in low-light conditions. To conserve power the optical unit will be triggered upon detection from the acoustic unit, and will use the results from the acoustic localization. The system will be modular, both in term of performance and in terms of composition, and will adapt to different scenarios and cost requirements.
SYMBIOSIS will involve the university of Haifa, Israel (four groups); IMDEA Networks, Spain (two groups); Wireless and More, Italy; and EvoLogics, Germany. The academic partners have already developed all the technical components of the system, and have demonstrated preliminary results in multiple sea experiments. The industry partners have substantial experience with integrating acoustic and optical components for long-term sea development, and is a leading firm for the development of realtime underwater signal processing.
