Technological developments (ToR d) : Creel fishing and acoustic tracking trials in the No-Take zone off Palamós-Roses (Northwester Mediterranean Sea) at 350-420 m depth

4 pages, 5 figuresThe OBSEA as testing site for acoustic tracking technologiesFixed-point cabled observatories provide highly-integrated biological and environmental data measurements that are continuous (i.e. benefitting from nearly unlimited power supply), and at very high frequencies, allowing species counts to be corrected by intrinsic species-specific bio-rhythmic fluctuations in response to environmental cycles (reviewed by Aguzzi et al., 2012; Da-novaro et al., 2017). The dataset of images acquired by the camera installed on the OBSEA obser-vatory (www.obsea.es) was used to track burrow emergence in 3 Nephrops norvegicus specimens (Figure 2.1.1), hosted in artificial burrows (i.e. the deployment depth of the infrastructure is shal-lower than the populations range of distribution in the Mediterranean
