Phenotypic and Genetic Components for Growth, Morphology, and Flesh-Quality Traits of Meagre (<i>Argyrosomus regius</i>) Reared in Tank and Sea Cage

Meagre (<i>Argyrosomus regius</i>) plays an important role in the aquaculture system, with the potential for diversification of European aquaculture, and is characterized by its fast growth rate, low feed conversion ratio, and the high quality of the product. Focusing on the relevance of...
