We are establishing a strategic alliance to develop reproductive protocols that enable more stable, efficient, and sustainable production<\/strong><\/h2>\n\n\n\n

We have started a collaboration with Safiestela, one of the leading producers of sole (Solea senegalensis), to tackle one of the major challenges in the aquaculture sector: the captive reproduction of this highly valued gastronomic and commercial species. Our goal is to develop reliable reproductive protocols to stabilize production.<\/p>\n\n\n\n

This research project will last four years. Specifically, it focuses on optimizing reproductive synchronization and improving the quality of gametes (both oocytes and sperm) to support efficient, stable, and sustainable production.<\/p>\n\n\n\n

A new unit with IRTAmar technology to face the challenge<\/strong><\/h3>\n\n\n\n

To carry out this research, we have adapted our facilities with a new dedicated unit for the maintenance and management of sole broodstock. This unit incorporates IRTAmar technology, which allows us to control environmental parameters such as photoperiod and water temperature\u2014two key factors for inducing sexual maturation and improving spawning synchronization<\/strong>.<\/p>\n\n\n\n

In addition, we are working with hormonal protocols, nutritional strategies, and advanced techniques such as in vitro fertilization and sperm cryopreservation. All of this will help us identify individuals with the best reproductive potential and optimize production quality.<\/p>\n\n\n\n

Research for more efficient and sustainable aquaculture<\/strong><\/h3>\n\n\n\n

Senegalese sole is a species of high strategic interest for European aquaculture. Although its production reached 2,600 tonnes in Europe in 2024, significant challenges remain in consolidating its captive reproduction. The main obstacles include lack of spawning synchronization, low quality of second-generation sperm, and the need for more efficient fertilization protocols.<\/p>\n\n\n\n

According to our researchers Neil Duncan and Elvira Fatsini, from the aquaculture program, \u201cour challenge is to better understand the reproductive physiology of sole in order to apply concrete and effective solutions. This collaboration will allow us to develop robust reproductive protocols and transfer this knowledge to the sector to promote more efficient and sustainable aquaculture.<\/strong>\u201d<\/p>\n\n\n\n

This initiative consolidates a strategic partnership between IRTA and Safiestela. At the same time, it highlights the value of public-private collaboration in addressing real-world challenges in the sector.<\/p>\n\n\n\n

Finally, we are working together to identify funding opportunities that will allow us to scale this research. This will help us move toward fully industrialized, sustainable sole production adapted to future challenges.<\/p>\n\n\n\n
