Cynoglossus semilaevis

Cynoglossus semilaevis, commonly known as the Chinese tongue sole, is a popular aquaculture flatfish species. They are native to China's northern coast but have experienced overfishing these past three decades. Tongue sole farming began in 2003 and they have since become a popular, expensive seafood. However, tongue soles have created issues for farmers due to their pathogen susceptibility and uneven sex ratio.
