   \n\n\n\n<p>By using AZTI&#8217;s FADs Echosounders it is possible to achieve:<\/p>\n\n\n\n<ul><li>Improve the estimate of biomass in tonnes for tuna and non-target species thanks to the sonar beacons;<\/li><li>Discriminate small tunas thanks to the sonar beacons;<\/li><li>Discriminate non-target species thanks to the sonar beacons.<\/li><\/ul>\n\n\n\n<p>FAD echosounders allow improved biomass estimation in tonnes for tuna and non-target species thanks to the sonar beacons.<\/p>\n\n\n\n<h2>Benefits<\/h2>\n\n\n\n<ul><li>To know the biomass associated with a floating object more precisely, both for fishing and for study;<\/li><li>To know the groups of species associated with a floating object, both for more selective fishing and for its study.<\/li><\/ul>\n\n\n\n<h2>Fields of application<\/h2>\n\n\n\n<ul><li>Buoy marketing companies;<\/li><li>Fishing sector;<\/li><li>Scientific community;<\/li><li>Public administrations and official bodies wishing to avoid fishing for non-target species in the tropical tuna purse seine fleet.<\/li><\/ul>\n\n\n\n<blockquote class=\"wp-block-quote\"><p>AZTI is the only institute in the world that works with the sonar beacons used by the fishing industry to geolocate floating objects.<\/p><\/blockquote>\n\n\n\n<h2>Proven expertise<\/h2>\n\n\n\n<ul><li>AZTI is the only institute in the world that works with the sonar beacons used by the fishing industry to geolocate floating objects;<\/li><\/ul>\n\n\n\n<ul><li>More than 10 years of research on species associated with drifting floating objects, using acoustic and tagging techniques;<\/li><li>Multidisciplinary team, specialised in fisheries technology, eco-ethology of species of interest and underwater acoustics;<\/li><li>Members of acoustics expert committees (ICES acoustics working group) and members of the ISSF by-catch scientific committee;<\/li><li>Specific technologies involved:<ul><li>Simrad 38, 120 and 200 kHz Simrad scientific sounders;<\/li><li>Acoustic marking listening stations;<\/li><li>Environmental satellite maps (altimetry, temperature, chlorophyll, etc.)<\/li><\/ul><\/li><\/ul>\n\n\n\n<h2>Success stories<\/h2>\n\n\n\n<ul><li>FADIO Project, study of FADs (floating objects) as observatories of the pelagic environment: acoustic study prior to species recognition;<\/li><li>Project Selectun, study of the behaviour and discrimination of tuna thanks to sonar beacons;<\/li><li>EU MADE project: improvement of algorithms for estimating the biomass of species associated with floating objects and study of aggregations under the derived floating objects (behaviour in relation to environmental parameters);<\/li><li>A doctoral thesis on obtaining abundance indices from sonar beacons and for the study of tuna dynamics in relation to environmental variables;<\/li><li>Two scientific publications (Lopez et al 2013 submitted) on the use of sonar beacons and the improvement of biomass estimates.<\/li><\/ul>\n\n\n\n<p><\/p>\n","protected":false},"featured_media":6220,"parent":0,"menu_order":0,"template":"","contexts":[207,203],"application":[54],"yoast_head":"<!-- This site is
