Freshwater mussels are the most endangered species in the United States. Zebra mussels are greatly impacting the freshwater mussel population. Since both types of mussels are filter feeders and eat detritus in the water, zebra mussels tend to eat the food before the mussels, and cause them to die. However, zebra mussels also attach to the mussel's siphons on their posterior end. This causes them to not only starve, but also suffocate because they cannot get any dissolved oxygen in the water.
From their first appearance in American waters in 1988 zebra mussels have spread to a large number of waterways, including the Mississippi, Hudson, St. Lawrence, Ohio, Cumberland, Missouri, Tennessee, Colorado, and Arkansas rivers disrupting the ecosystems, killing the local unionid mussels, (primarily by out competing native species for food) and damaging harbors, boats, and power plants. Water treatment plants were initially hit hardest because the water intakes brought the microscopic free-swimming larvae directly into the facilities. Zebra mussels are now believed to have cost North America billions of dollars in impacts each year, illustrating the costly effects of invasive species.
This is what makes the Quagga scary. They are preying on the predators (Zebra mussels. There was a gentleman in an earlier post that commented on water clarity and the fact that the fish were eating the Zebra's. Water clarity is not always a good thing and it appears that tghe Quagga's are wiping out the Zebra's. I really that from these posts we can create, at the very least, an awareness about this predator. The delta would be an ideal home for it.

Hmmmmmm, maybe these things will get into the drb2@gr5tmn water pumps in Tracy and plug them up! Then the Delta could keep the water which belongs there........and the salmon and strippers and other fish can once again thrive here!
I don't know what variety of native mussels we have in the Delta, but they are larger than the Zebras and Quaggas and are an important food for a lot of animals from sturgeon to racoons. The Delta is not that important as a feeding ground for the salmon, they mostly pass through it on the way to the sea or to the spawning streams. A lot of work has to be done on the remaining undammed rivers and streams before we will see an improvement in wild salmon numbers.
Stripers are not a native species to the California Delta. They were deliberately introduced as a game fish during the late 19th century. The good news is that stripers do not compete with salmon in a significant way. No reason why we can't have both species in the delta.
pkjryan: The muddy bottoms in the Delta won't be a problem for Quaggas? From the story you provided it looked like they like sand and rock bottoms.

I don't believe so. One of the seminars that I attended instructed you to look in the mud for evidence of mussels. Even so, they like to attach themselves to substrates such as pilings, boats, and etc. I am sure they would have no troubles finding a home. It's funny, I had the opportunity to work with one of Solano counties boat patrols last weekend and they were unaware of the problem. We need these people on board as well if we are to have some early detection. I do know that Nevada has had the same problem.
