Detailed explanation-1: -Water clarity Mussels are filter feeders, which means they feed by clearing nutrients from the water passing through them. The rate of reproduction and spread of zebra mussels make them efficient cleaners of Great Lakes water, but whether that’s a positive or negative thing depends on who you’re asking.
Detailed explanation-2: -Zebra mussels can render beaches unusable, clog water filtration pipes, and destroy boat engines such as in example pictured above. Although small, zebra mussels cause big trouble. These mussels can quickly encrust things, such as this crayfish above.
Detailed explanation-3: -The species was unintentionally introduced into the United States’ Great Lakes through the discharge of contaminated cargo ship ballast water. They were first discovered in the Great Lakes in 1988 and were first confirmed in the Duluth/Superior Harbor in 1989.
