It is widely known that to achieve sustainable fishing is necessary measures to monitoring control and surveillance (MSC) to ensure the compliance of politics to protect and conserve marine life and oceans. Recently, the development of new technologies of electronic monitoring (EM) have involved a new possibility to authorities and research institutions to have a better knowledge of fishing operation and their impact in marine ecosystems. These tools constitute a robust method to obtain a fully document fisheries (FDF) and to compliance with mandatory politics as Common Fisheries Policy (CFP) in the European Union. Furthermore, the traditional methods to obtain data is limited, nevertheless, EM has the potential to increase fleet coverage. TIPES project aims to develop a new electronic monitoring scheme to improve fisheries management. We employed a methodological approach to assess the potential implementation of these technologies. We tested three data sources: human observation, the electronic tool called "iObserver", developed as part of the project, and the electronic surveillance cameras system. The comparative essay has been carried out in two cases of study in Spanish fisheries at Atlantic Iberian waters, targeting the otter bottom trawl demersal fishery (OTB_DEF) and the otter bottom trawl pelagic fishery (OTB_MDP). Experimental trials were performed on board of collaborative commercial vessels during normal fishing operations. Onboard observers recorded data of fishing operations, including fishing yields (retained and discarded catch biomass), species composition and biological information. Moreover, this collected information has been analyzed following a standardized protocol and the advantages and disadvantages of each methodology have been evaluated. Results indicated that electronic monitoring with “iObserver” has the potentially of recording species composition and total catch biomass while electronic surveillance cameras identify the retained and discarded species as well as bycatch events and give information when human observer is not present

Thanks to the General Directorate of Sustainable Fisheries (Ministry of Fisheries) for the support in the development of the study. This work was made within the MAP-COV-3-TIPES project funded by General Secretary of Fisheries under the NextGenerationEU
