Seaweed eating opaleye and mullet

Today, we have photographed a picture of a bird eel and a mullet eating algae. The place is Jeju Island Gimyeon breakwater. There were many seaweeds attached to the rocks around the breakwater, and venguet ducks and mullets were attached to the rocks to eat algae. When I picked a fishing point for shooting today, I knew that it would be a way to check if the algae that feed the target fish were around or not.
