Until now, sex differentiation was carried out mainly using ultrasound scans, which are more invasive procedures and can only be applied at advanced stages of development.<\/p>\n\n\n\n<p>The system developed by AZTI requires only a small tissue or blood sample, which makes it easier to apply in juvenile stages and allows feeding and husbandry practices to be tailored from the very beginning of the production cycle.<\/p>\n\n\n\n<p>This tool will enable aquaculture companies to select females from early stages, reduce rearing costs, optimise sex-specific feeding and husbandry, and improve the profitability and sustainability of caviar production.<\/p>\n\n\n\n<p>The work was carried out in collaboration with Caviar Riofr\u00edo (Osborne Group) and is fully aligned with the purpose of the JACUMAR Award: to promote applied research that strengthens the competitiveness of the aquaculture sector and supports more sustainable production.<\/p>\n\n\n\n<p>The JACUMAR Award, worth 20,000 euros, is granted annually to research projects that bring innovation and improvements to Spanish aquaculture.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>On 24 November, coinciding with Aquaculture Day organised by the General Secretariat for Fisheries, AZTI received the 14th JACUMAR Research in Aquaculture Award from the Spanish Ministry of Agriculture, Fisheries [&hellip;]<\/p>\n","protected":false},"author":19,"featured_media":43422,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_price":"","_stock":"","_tribe_ticket_header":"","_tribe_default_ticket_provider":"","_tribe_ticket_capacity":"0","_ticket_start_date":"","_ticket_end_date":"","_tribe_ticket_show_description":"","_tribe_ticket_show_not_going":false,"_tribe_ticket_use_global_stock":"","_tribe_ticket_global_stock_level":"","_global_stock_mode":"","_global_stock_cap":"","_tribe_rsvp_for_event":"","_tribe_ticket_going_count":"","_tribe_ticket_not_going_count":"","_tribe_tickets_list":[],"_tribe_ticket_has_attendee_info_fields":false},"categories":[3],"tags":[],"tax-big-challenge":[42,36],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v18.4.1 -
