Transcript of Southern Clubshell
By: Branson Wetzstein
Once found in every major river in Mississippi, Alabama, and Georgia
Now, found mainly in Alabama and scarcely in Mississippi and Georgia
How Many are Left?
Decreasing, however, at a slower rate.
Was once declining at 70-80%, now at 60%
Flowing water, streams, rivers
Blacktail Shiners - Young Clubshells need this fish to grow, find food, and for protection
Normal river/stream organisms
eats algae, small plants, small animals, and possibly bacteria
Fishes, turtles, muskrats, raccons, and otters
Two sheels - Used for protection from predators and environment
Helps collect food
Uses the Blacktail Shiner and other similar fish while developing to avoid predators and assist in filter feeding
Burrows in sand and gravel
Hiding in sand and gravel protect and camouflage the Clubshell from predators
Help determine water quality
Sensitive to pollution
Keeps water clean
Relatively reliable food source for other animals (before population decline)
Reasons for Decline
Sensitive to pollution and toxin in the water
Dumping excess sand and gravel into streams crush and deplete oxygenation in streams, therefore, killing Clubshells
Bringing carrier fish to streams and rivers to help Clubshell development
Safe Harbor Agreement in Lee County, Alabama
Stop pollution, dumping
Attaches to several breeds of fish's gills to ensure safety
Green spotted shells in childhood, deep yellow in adulthood
Used to be incredibly common all over MS, AL, and GA. Now, only 6 viable locations exist
