For this reason, a large part of the Basque quota is currently transferred to other regions of Spain.<\/p>\n\n\n\n<p>To reverse this situation and encourage the recovery of bluefin tuna fishing in this coastal area, two submersible aquaculture facilities will be installed 3.688 miles from the port of Getaria (Gipuzkoa). These cages will be tested during the autumn and winter months, and in the summer of 2025 the pilot test for the fattening of this species will begin with a limited number of specimens.&nbsp; If the experience is positive, more cages will be installed from 2026 onwards, depending on the fishing quota for fattening.<\/p>\n\n\n\n<p>The initiative, presented today at a press conference by Itsasbalfeg\u00f3, a company created by the <strong>AZTI<\/strong> technology centre and the Catalan company <a href=\"https:\/\/balfego.com\/en\/\"><strong>Balfeg\u00f3<\/strong><\/a><strong>,<\/strong> plans to catch live bluefin tuna using purse seine gear in collaboration with the Basque fishing fleet.&nbsp; Subsequently, the catches will be fattened, with the aim of assessing both their economic and environmental viability.<\/p>\n\n\n\n<p>\u2018The main challenge will be to determine whether it is viable to use purse seine gear for bluefin tuna fishing in the Bay of Biscay. If this is achieved and, subsequently, the fattening in cages is successful, this project could have a very positive impact on the Basque economy and society, making it possible to revalue fishing quotas, improve the quality of the product and optimise fisheries management,\u2019 said Juan Jos\u00e9 Navarro, assistant director of Balfeg\u00f3, a leading company in catching, feeding, studying and marketing bluefin tuna.<\/p>\n\n\n\n<p>\u2018The main challenge will be to determine whether it is viable to use purse seine gear for bluefin tuna fishing in the Bay of Biscay.

This first stage has also been approved by the International Commission for the Conservation of Atlantic Tunas (ICCAT), which will evaluate the results obtained,\u2019 said Rogelio Pozo, director of AZTI.<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-large\"><img loading=\"lazy\" width=\"850\" height=\"533\" src=\"https:\/\/www.azti.es\/wp-content\/uploads\/2024\/09\/Instalaciones-acuicolas.jpg\" alt=\"\" class=\"wp-image-38595\" srcset=\"https:\/\/old.azti.es\/wp-content\/uploads\/2024\/09\/Instalaciones-acuicolas.jpg 850w, https:\/\/old.azti.es\/wp-content\/uploads\/2024\/09\/Instalaciones-acuicolas-300x188.jpg 300w, https:\/\/old.azti.es\/wp-content\/uploads\/2024\/09\/Instalaciones-acuicolas-768x482.jpg 768w, https:\/\/old.azti.es\/wp-content\/uploads\/2024\/09\/Instalaciones-acuicolas-450x282.jpg 450w\" sizes=\"(max-width: 850px) 100vw, 850px\" \/><\/figure><\/div>\n\n\n\n<h2><strong><strong>Testing phase and continuous monitoring<\/strong><\/strong><\/h2>\n\n\n\n<p>Prior to the start of tuna catching, scheduled for the summer of 2025, Itsasbalfeg\u00f3 will validate this autumn and winter the buoyancy, immersion capacity and resistance of the cages to the adverse weather phenomena of the Bay of Biscay, a key challenge for this type of aquaculture.<\/p>\n\n\n\n<p>\u2018Balfeg\u00f3 has been running a similar facility in L&#8217;Ametlla de Mar (Tarragona) since 2004, but the conditions in the Bay of Biscay are much more severe, especially in winter. The technology of the cages, with a diameter of 50 metres, is designed to withstand these conditions and minimise the impact of waves,\u2019 explained Navarro. In the event of a storm, the cages can be submerged up to 18 metres to protect both the structure and the fish.<\/p>\n\n\n\n<p>Throughout the project, state-of-the-art sensors and cameras will be used to monitor water quality and biological activity around the cages in real time, ensuring an immediate response to any possible environmental impact.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Two pioneering submersible aquaculture facilities installed off Getaria will be tested in 2025 to fatten a limited number of tuna.
