The following is an incomplete list of aquatic invasive animals found in, or adjacent to, the Capital-Mohawk PRISM. Click on the name to read individual species details courtesy of NYIS. For information on the difference between an emerging and widespread aquatic animal, check out our Tier List, which ranks the species of concern for the region in order of abundance and management strategy. Tiers 1 and 2 are considered emerging species which need to be responded to quickly once found.

Emerging

Emerging aquatic animals are species that have not established fully in the region, giving us a chance to stop these invaders in their tracks through eradication and rapid response efforts. If you believe you have identified one of these animals, please contact PRISM staff using the contact page and/or upload your observation to iMapInvasives.

​Factsheets for each of these species are coming soon.

​Tier 1 Species (Not yet in PRISM):

• Cercopagis pengoi, Fishhook Waterflea
• Channa argus, Northern Snakehead
• Gambusia affinis, Western Mosquitofish
• Hypophthalmichtys sp., Asian Carp
• Limnoperna fortunei, Golden Mussel
• Misgurnus anguillicaudatus, Oriental Weatherfish
• Neogobius melanostomus, Round Goby
• Potamopyrgus antipodarum, New Zealand Mud Snail
• Procambarus clarkii, Red Swamp Crayfish
• Tinca tinca, Tench

Tier 2 Species (Eradication in PRISM is feasible):

• Bythotrephes longimanus, Spiny Waterflea
• Cygnus olor, Mute Swan

Widespread

Widespread aquatic animals are species that have established themselves in the region, leading to the use of multiple management practices. These practices primarily include containing a species if it is in a low enough abundance and/or developing local management strategies to suppress their impacts.

​Factsheets for each of these species are coming soon.

• Bithynia tentaculata, Mud Bithynia (Faucet snail)
• Carassius auratus, Goldfish
• Cipangopaludina chinensis, Chinese Mysterysnail
• Corbicula fluminea, Asian Clam
• Cyprinus carpio, Common Carp
• Dreissena sp. (bugensis & polymorpha), Quagga and Zebra Mussel

• Eriocheir sinensis, Chinese Mitten Crab
• Hemimysis anomala, Bloody Red Shrimp
• Orconectes rusticus, Rusty Crayfish
• Scardinius erythriphthalmus, Rudd
• Trachemys scripta elegans, Red-eared Slider (turtle)
• Vivaparus georgianus, Banded Mysterysnail
