European Rud
| Scientific Name | (Scardinius erythrophthalmus) |
|---|---|
| Classification and Permitting Level | 1 - Prohibited Aquatic Nuisance Species |
| Species Description | European rudd is a minnow that can reach about 19 inches in length and 5 pounds. It is distinguished from native golden shiners by having bright red fins, red eyes or eyes with a red spot, and scales on the ventral keel. |
| Preferred Habitat | It can typically be found near the bottom of lakes, ponds, rivers, and streams near vegetation. |
| Reason for ANS Designation | This fish may compete with native fish for food and readily hybridizes with the native golden shiner. Once established, there is no good control method. |
| Place of Origin | Round goby is native to Eurasia but was first documented in the United States in the late 1800s or early 1900s. The initial introduction was likely as a food or game species. More recent introductions have likely occurred from bait releases. |
| Stopping the Spread | Never release unused bait back into a waterbody, and do not attempt to stock a new species into a waterbody. Besides usually being illegal, new introductions of fish species may disrupt the current ecosystem. |
