Itis New trawl methods for targeted fishing

The ITIS project, officially recognised in 2006, was designed to offer the fishing industry innovative technqiues and methods for sustainable fishing.

The project first developed a new acoustic tool for identifying acquatic reources and ecosystems for real-time multifrequency characterization of biological targets. The system is compatible with and can be intergrated into different acoustic platforms: single and multi-beam probes, sonar, autonomous instrumented stations and net sounder. The second part of the project developed and experimented with new designs for fish and lobster pots combining selection and quality criteria for catches. At the same time, work was carried out to optimize trawler design to reduce the mechanical impact on catches and sea beds, thus reducing the vessel's energy consumption.

In addition to these products, the project also strengthened exchanges between scientific, industrial and profressional partners relating to the two theses undertaken at the University of Université de Bretagne Sud and Télécom Bretagne, recruitment of a designated employee at IRD and registration of 3 interim French patents ('enveloppes Soleau'). New contacts were established for technology transfer: experiments with pots and creels in the fishing grounds of the Gulf of Gascony (Prespo project with Aglia) and alternatives to longline fishing for Toothfish in the Pacific (Orcasav project, recognised jointly with Qualitropic).
