Vina: The corvina fish is the name given to different species of marine fish of the family Sciaenidae, within the order Perciformes. The best known species are the corvina or perch regia and the black croaker, very typical of the Mediterranean Sea. At present, there are aquaculture projects focused on these species in which the production of fertile eggs by hormonal induction has been achieved, with moderate success in the survival of the larvae.
