Centerpin fishing, also called float fishing, is a fishing technique which uses a mooching rod, reel and fly. The method is used behind boats for steelhead fishing in salt water, and is currently popular with freshwater salmon anglers who drift their boat down a river.

Although centerpinners (sometimes called "pinners") use a fly, it is not really fly fishing, which involves more skill and less salmon roe. Centerpin rods are generally better for catch and keep fisheries, such as salmon, because the long lengths of line and lack of drag make it much harder to release the fish unharmed. The technique originated in Europe. It is a stealthy method of fishing, effective for catching many of the highly prized European rough fish.
