Over the last 3 years while out fishing on the East Anglian rivers,and drains. I have encountered several none native species.
These have included, Grass Carp, Ghost Carp, Asian Silver Carp, common and fancy goldfish, Golden Tench, Golden and blue Orfe, Common Sturgeon and Pumpkinseed fish.
Most of these are common fish for aquarist and pond keepers. Some are genuine escapes from ponds, in gardens that have been flooded. Some have been dumped because they out grew there ponds or tanks and some because they have started to eat their neighbours.
I have been hearing rumours lately of other alien species in the rivers.
European Asp. Accidently stocked from the ballast tanks of a German timber vessel.
American Largemouth Bass, Accidently stocked from the ballast tanks of a Dutch vessel. Apparently a population is thriving in Holland, which arrived from the Great Lakes area of the USA. Some of these were accidently picked up and transported to Britain.
Mississippi Paddle fish (polydon spathula). Dumped by pond keepers because they became to large for the ponds they were kept in.
Blue Catfish (ictalurus furcatus). Dumped because they started eating their neighbours.
Does any one else have knowledge or an angling experience of the above listed or any other none native species in the British river systems.
