Sea bass (Dicentrarchus labrax) divergent lines (for growth and fasting tolerance) phenotyping for feed efficiency, weight loss at fasting, growth and sex ratio.

This study focusses on 600 fish from four divergent fish lines (high and lowgrowth rate, high and week fasting tolerance). For each fish the following data is being generated: phenotypic data (sex, growth indexes, fasting tolerance and risk-taking behaviour), raw genomic data (Illumina 3KSNPchip and potentially RNAseq data for 65 samples), and analysed genomic data (genetic map, QTL mapping, RNA differential expression data).The scientific question behind this study can we evaluate individual feed efficiency of fish, and can we find genomic clues of evaluation of this phenotype for leading genomic selection of feed efficiency in breeding programs.
