Sumario:[EN] The ICCAT North Atlantic Albacore (Thunnus alalunga) Research Program was established to enhance knowledge on albacore to provide more accurate scientific advice to the Commission. Funds are provided to the Albacore Species Group to develop research activities to accomplish several objectives. One of the research objectives is to increase knowledge on reproductive biology for the northern Atlantic stock, maturity schedules (L50) and egg production (size/age related fecundity). In March 2023, Terms of Reference were published by ICCAT. A Consortium integrated by Canada, Chinese-Taipei and Spain presented an offer to collect gonad samples throughout the year 2 0 2 3 and carry out the study of reproductive biology on the 2022 samples collected for the North Atlantic albacore stock. Results of the histological analysis of gonads sampled are presented.
