Genetic parameters and genotype by environment interaction for production traits and organ weights of gilthead seabream (Sparus aurata) reared in sea cages

Gilthead seabream is a key fish species for farming in the Mediterranean region and is farmed in a large geographical area under various production circumstances. However, more than 80% of the genetically improved fingerlings originate from a single country, Greece, which poses a potential risk for genotype by environment interaction (GxE). Therefore, the objective of this study was to quantify GxE for several traits of gilthead seabream in two...
