An angler with pots is someone who uses a fishing rod and bait to catch eels. This type of fishing is done by dropping a line with a hook and bait into the water, and then waiting for an eel to take the bait. The angler then pulls the eel out of the water using the rod and places it in a pot. This type of fishing is popular in many parts of the world, and is often used to catch eels for food or for sale.
