Caught congers is a type of fishing that involves using an eeled line to catch conger eels. This method of fishing is popular in the United Kingdom and Ireland, where conger eels are abundant. The eeled line is made of a long, thin line with a hook at the end, which is baited with baitfish or squid. The angler then casts the line into the water and waits for the conger eel to take the bait. Once the eel is hooked, the angler must carefully reel it in.
