To aid in prevention, ecologists, naturalists, and others around the Great Lakes region have encouraged boaters to inspect their hulls and motors and thoroughly drain and dry water-holding compartments between outings. Rinse them to get rid of any debris or seaweed on their outer shells. Diarrhea. Floriculture members are encouraged to . Until now, no one has been able to pin down why the worlds wild, freshwater musselsoften unnoticed and underappreciated engineers of stream and river healthare facing massive, unexpected die-offs.

"We can see the mussels because they're on the shoreline, but to a large extent, oceans are out of sight, out of mind, so we're likely to learn the magnitude of what's happening only much later. [15], Research on natural enemies, both in Europe and North America, has focused on predators, particularly birds (36 species) and fish (15 species eating veligers and 38 eating attached mussels). Mussels lure fish in to host their parasitic larvae. Zebra mussels do not attach to cupronickel alloys, which can be used to coat intake and discharge grates, navigational buoys, boats, and motors where the species tends to congregate. There are several ways to wreck a moss ball. Gillnets set in the littoral and sublittoral zones during the feeding period consist mainly of large roach and perch while vendace were prevalent in the pelagic zone. "If it happens that frequently, the system won't have time to recover in between the die-offs," he said. If any mussels are open, tap them gently against the counter and discard any mussels that don't close up within a few minutes. "Zebra mussels are basically living at the edge oftheir thermal tolerance here for heat, and so, during our hot summers, they are basically just trying to survive," she said.

Unexplained mussel die-offs have been documented across the United States and in Europe. Tragically, these events rarely get noticed. These plants, when decaying, wash up on shorelines, fouling beaches and causing water-quality problems. Look at the crack where the two shells meet and you'll see a little 'tag' of what looks like threads .

Several hundred thousand can crowd a single square meter, and theyre persistent: They hide in tangles of aquatic plants snagged on motors, can colonize essentially any hard surface, and are able to survive outside the water for several days.
