Drums
This category includes yellowfish = yellow croaker (pictured), corvina = spotfin croaker, drum, redfish = red drum, white sea bass, kingfish, weakfish, and spot. Substitutes: hake (tastier) OR mullet OR tuna OR red snapper OR pompano
Another site calls it white sea bass.
There's also a fish called a corbina, but I can't tell from a quick hunt whether it's the same or related or different altogether.
