The zebra mussel (Dreissena polymorpha) is a small freshwater mussel, an aquatic bivalve mollusk in the family Dreissenidae.The species originates from the lakes of southern Russia and Ukraine, [3] but has been accidentally introduced to numerous other areas and has become an invasive species in many countries worldwide.
Zebra mussels are consumed by freshwater drum once they reach a length of 25 cm (9.8 in), but drum under 35 cm (14 in) in length only eat small mussels and reject the larger ones. [28] The fish larger than 35 cm (14 in) exhibit less selectivity and consume mussels relative to their availability in lakes. These larger fish are not restricted by ...
The quagga mussel resembles the zebra mussel, just as its namesake (quagga) resembles the zebra. The quagga mussel shell can be distinguished from the zebra mussel shell because it is paler toward the end of the hinge. It is also slightly larger than the zebra mussel, about 20 mm (0.8 in) wide, roughly about the size of an adult human's thumbnail.
The Iowa Department of Natural Resources confirmed zebra mussels, an invasive species, were found in Saylorville Lake.
Dreissena is a genus of small freshwater mussels in the family Dreissenidae in the class Bivalvia. They are found attached to firm substrates by threads from underneath the shells and are the only freshwater bivalves to attach to hard substrates in high densities while having a planktonic larval stage.
The zebra mussels can use up all the food in the vicinity and deplete the oxygen, and may also consume the native mussels' larvae and sperm, preventing reproduction. Deposits of waste products degrade the habitat. [7] Other invasive species include the Asian clam (Corbicula fluminea), which competes with the native mussel and consumes its sperm ...
Zebra mussels attach to boats and anything left in the water, including anchors, and can survive for days out of water, often hiding in crevices where they may escape notice.
The Brushy Creek Municipal Utility District said it's no longer worried about an aquatic invader that has taken over dozens of lakes across Texas.
