Some exotic freshwater fish are serious pests within our waterways. Several species are listed as unwanted organisms by the Ministry for Primary Industries.
The Marlborough District Council and Department of Conservation are concerned about the risk exotic pest fish pose to the aquatic environment. They welcome any information about the occurrence of pest fish within the district and will attempt to control incursions when they occur.
If you see rudd, tench, koi carp, perch, gambusia, catfish or any other freshwater fish you don’t recognise in any water body or garden pond please report it immediately to the Marlborough District Council or Department of Conservation.
