Polish nationals are fishing Dutch lakes and rivers free of carp and pike to eat or sell on the black market, the Telegraaf claims on Friday, quoting local fishing clubs.

The situation is so serious that the clubs are now employing extra controllers and publishing information in Polish, the paper says.
The problem has arisen because eastern Europeans do not put the fish they catch back, the paper says. ‘The have other ethics and culture,’ a spokesman for the national fishing organisation Sportvisserij Nederland said.
