Abstract

Critical swimming speed (Ucrit) is an important measurement of swimming performance as well as a good indicator for cardio-respiratory health. It offers a new opportunity to select fish with better fitness. Here we present results from a GWAS study on critical swimming speed and growth in Nile tilapia under conditions of recurrent hypoxia. Heritability for Ucrit was moderate (0.31±0.04). Large fish generally swim faster than smaller fish, whereas fish with better swimming performance tend to show slower growth later in life. Nine suggestive SNPs associated with swimming performance were identified under a hypoxic environment. A clear pleiotropic effect on growth traits was found for some of the SNPs associated with swimming performance, while other SNPs had only an effect on swimming performance, but not on growth. Our analyses sheds a first light on the genomic mechanisms of swimming performance and growth in Nile tilapia.
