Zebra mussels and the closely related and ecologically similar quagga mussels are filter-feeding organisms; they remove particles from the water column. Zebra mussels process up to 1 litre (0.26 US gal; 34 US fl oz) of water per day, per mussel. [9] Some particles are consumed as food, and feces are deposited on the lake floor.
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 primary diet of round gobies includes mollusks, crustaceans, worms, fish eggs, zebra mussels, small fish, insect larvae, and other small invertebrates (insects and amphipods) living on the bottom of lakes and streams. [4] In spring, the main elements of their diet in the Sasyk Lagoon are Hydrobia, Cerastoderma, and Abra. [7]
Starting Nov. 1, all boats entering the two lakes will be inspected for both mussels, he said. “Our job is to make sure it’s not getting into the lake,” Duprey said. “The impacts can be ...

Aug. 18—At least 12 invasive zebra mussels were found in aquatic moss balls sold for aquariums in a Renton, Washington, Petco on Aug. 5. The mussels, which are native to freshwater bodies in ...
Zebra mussels are filter feeders, meaning that they consume microorganisms, and they do so at very fast rates. Microorganisms form the bottom of the food chain, and eliminating that food source can be dangerous to the survival of native species. The spread of the nonindigenous zebra mussels have greatly decreased the numbers of native mussels ...
The most common types of dreissenids are Dreissena polymorpha (Zebra mussel) and Dreissena rostriformis (Quagga mussel). [14] These mussels damage both ecological systems and human infrastructure. In North America, biofouling caused by dreissenids created 267 million dollars’ worth of damage between 1989 and 2004. [ 14 ]
