I know of a local day ticket with an HONESTY Box, completely emptied of all fish species & even ducks by EE'S. Blatantly just cooking up on the Bank.
Local park lake, has mesh stone crates reinforced banks. They started with cord tied to branches, which were quickly removed, they then started tying the cord to the mesh crates slightly underwater, sneaky bar stewards. A landing net pole or stick walked around the margins is how we tried to dispatch them, but as with anyone trying to get something, they were determined to have a free lunch and have slowly emptied it.
The other year one of chefs from a local Chinese restaurant was caught with a carrier bag full of ducks from the pond too!!
