In the last 20 years, the production of farmed marine fish species has increased rapidly, mainly as a consequence of improved breeding methods and technologies. Skeletal malformations and others severe production bottlenecks such as high larval mortality or susceptibility to stress and disease, remain to be solved. Skeletal anomalies in farmed fish are a relevant issue affecting animal welfare and health and cause significant economic losses. The constant progress of genomic technologies promises to rapidly increase our knowledge on molecular mechanisms underlying productive traits of economic relevance in farmed species. The main objective of this PhD research was to investigate the molecular basis underlying the mandibular prognathism (...
