Dead quagga mussels are clustered for a stone at Lake Mead a year ago. The mollusks release toxins that may move within the system.
- Understood aliases: Chinquapin, Shellcracker, Mason Bream, Tupelo Bream, Mongrel Bream, Yellow Bream, Stumpknocker, GI (Government Enhanced) Bream
- The basic dorsal coloration is olive with darker specks.
- Redear depend mostly on mollusks for food and donвЂ™t compete heavily with insect-eating seafood. Redear have very developed grinding teeth вЂ” or shell crackers вЂ” in their throats. One's teeth crush snails, their fare of preference.
- Redear are typically based in the United that is southeast States but have already been introduced into a few states. Their normal range is from the Mississippi River basin in Indiana and Missouri south towards the Gulf Coast.
- Redear sunfish can surpass 10 ins in length and weigh over 4 pounds, making them sport fish that is popular.

Refresher course: The mussel risk
Mussels absorb toxins and hefty metals from the pond water and later expel them as highly focused pellets. Toxins could then enter the system whenever base dwellers eat the pellets. Quagga mussels may also create more favorable conditions for algae that will contaminate normal water with toxins.
Beyond the sun's rays
Nature seemingly have a brightly colored treatment for the quagga mussel intrusion at Lake Mead.
The redear sunfish is sat on the subs bench become introduced given that possible savior regarding the Las vegas, nevada ValleyвЂ™s primary water supply.
UNLV biologist David Wong, the regionвЂ™s chief quagga fighter, has very very very very long suspected that seafood appetite will be the answer that is best towards the clam infestation.
