Question: what is the difference between lean fish and fat fish?
Answer: Lean fish are those that are low in fat, such as flounder, sole, cod, red snapper, bass, perch, halibut and pike. Fat fish are those which are high in fat, such as salmon, tuna, trout, butterfish and mackerel. Lean fish, having almost no fat content, can easily become dry, particularly when overcooked.
