Eel buck

Eel bucks or eel baskets are a type of fish trap that was prevalent in the River Thames in England up to the 20th century. It was used particularly to catch eels which were a staple part of the London diet.

Eel bucks were baskets made of willow wood, and were often strung together in a fishing weir. Construction of such weirs was outlawed under the terms of Magna Carta
