As a member of the Group of Biology of Reproduction (GBR; est. 1997) main research objectives are: 1) to understand how fish integrate genetic and environmental information, particularly for the development of the sexual phenotype, 2) to develop biomarkers of key performance indicators and protocols for the control of reproduction according to sustainable aquaculture principles, and 3) to determine how species adapt to new environments in a global change scenario. To achieve this, we use economically-relevant species, the European sea bass, and modern genomic, epigenetic and transcriptomic methods.
