This research is of great interest, since it offers detailed information about genes that determine important traits such as growth rate. In addition, tools for chromosome mapping and kinship assignment, which are essential for genetic selection programs, have been validated. The results of this work, which has been carried out in collaboration with national institutions including the National Center for Genomic Analysis (CNAG-CRG), the National Institute of Toxicology and Forensic Sciences (INT), the University of Malaga and the University of Las Palmas de Gran Canaria, have been published in the prestigious Scientific Reports magazine. IFAPA has been working in the field of sole aquaculture for 20 years in the hope of optimising production, in technological developments, strategies for disease prevention, improvement of diet and growth, and morphological quality parameters. The work carried out so far has been in close collaboration with the industry to help it optimise production and select the ideal fish for recirculation farms.
