•Build it right. •Eliminate wild fish.•Stock it by the numbers.•Maintain fertility.•Keep out the weeds.•Harvest, harvest, harvest!
The Basic Principles
Build it right and the rest will follow.
• Pick the right site.• Core the dam.• Build to the right depth.• Slope the banks.• Choose the best spillway.• Seed the shoreline.
Pick the right site. It should have• a natural swale that catches surface water off the watershed—not a large spring or stream
• adequate clay (at least 20%) to seal the bottom
• a ratio of pond size to watershed to just keep the pond full with only occasional major flushing
Fishes that cause problems in bass-bream ponds
• crappie• bullheads• green sunfish & hybrid bream• golden shiners (only in weedy ponds)• gizzard shad
Stock 1,000 fingerling bream (800 bluegill and 200 redear “shellcrackers”)
per acre in the winter.
Bluegill, Lepomis macrochirus
• an alternative fish for anglers
• a fish that bites almost year-round
• an excellent eating fish
Channel catfish provide
but
Channel catfish can
• compete with bluegill when small• compete with bass when large• cause the pond to be muddy if too many are stocked
• Stock no more than 50/acre (100 per acre with feeders).
• Stock at the same time as the bass in new ponds.
• Stock with >8 in fish when stocking in established ponds.
Catfish stocking
A fertilized pond supports 300 to 400 lb. of fish per acre.
An unfertilized pond supports only 100 lb. of fish per acre.
Clearing muddy pondsFirst fix the source.
• Fence out livestock.
• Establish a good turf around the pond.
• Prevent excess runoff from construction or newly plowed fields.
• Remove common carp or excess catfish.
Clearing muddy pondsThen treat the problem.
• Raise alkalinity by liming and fertilizing.
• Add hay or cottonseed meal in winter months.
• Treat pond with gypsum or (if all else fails) alum.
Contact your county Extension agent before trying these treatments.
Apply lime at a rate of at least 2 tons per acre.
or
Consider the rate prescribed by the soil testing lab a minimum.
Apply as much lime as you can afford.
Application ratesFertilizer Rate Method Liquid 1 gal. Dilute in the prop
wash.
Water soluble
4 to 6 lb. Spread on the surface.
Begin fertilizing when water temperature hits 60 degrees F. Maintain a water clarity of 18 to 24 in.

Why should you control weeds?
• Weeds compete for nutrients.
• Weeds interfere with recreation.
• Weeds interfere with bass feeding.
• Weeds can cause oxygen depletion.
• Weeds can be unsightly.
Weed prevention
• maintain the pond with deep edges- no more than 20% of the pond less than 2 ft deep - livestock should be fenced out
• fertilize early in the year and maintain water clarity between 18 and 24 inches
A pond is in balance when there are the correct numbers of bass and bream permitting good growth and reproduction of all fish species.
In a fertilized pond, remove about 25 lb. of bass per acre each year.
In an unfertilized pond, harvest about 10 lb. per acre each year.
In a balanced pond, both angling and electrofishing catches should show a wide range of sizes of both bass and bream. These fish should be in good condition, neither overly thin or fat .
(See Extension publication ANR-1193, “Relative Weight: An Easy-to-Measure
Index of Fish.”)
Check pond balance in early summer using small-meshed 15-ft. seines.

In a bass-crowded pond, you find bass and bream fry and NO 3- to 5-inch bream. In extreme cases, no bass fry are found.
In a bluegill-crowded pond, you find NO or very few bass and bream fry andmany 3- to 5-inch bream. In extreme cases, you may find no bream fry.
To correct a bass-crowded pond• Correct weed problems.
• Maintain good fertility.
• INCREASE BASS HARVEST!!!
To correct a bluegill-crowded pond
• Try corrective restock with 4- to 6-inch bass if the problem is just beginning.
• Try marginal rotenone and corrective restock of bass.
• Start over.
Survey Results
• 51% never checked for balance or water quality
• 93% did not keep harvest records– Slow LMB growth most commonly reported
problem
Manage for trophy bluegill by underharvesting bass.
Manage for trophy bass by overharvesting (small) bass.
Forage enhancement for bream
Feed 1 to 10 lb. of floating pelleted catfish feed per acre per day during the growing season. Be careful not to overfertilize in combination with the feed.
Feeding will reduce the effectiveness of grass carp.
Nile Tilapia, Oreochromis niloticus
Tilapia only where it is legal: check with your local natural resource
agency. Must be restocked annually in areas where winter water Temp < 50 F
Threadfin shad, good for ponds 7 – 8 acres or larger. Will winterkill at water temp. <40 F. Does compete with bream but may not cause serious reduction.
Forage enhancement for bass• Stock adult tilapia in the spring. (where legal)
• Stock threadfin shad in larger ponds.
Shad will compete with bream, so expect reduced bream catches.
MAYBE NOT!
Pond Forage Enhancements
NO MAGIC BULLETT!!!
•Ecosystems have limits
•Ponds could still be bass-crowded with shad
A well-managed pond will provide many years of enjoyment with catch rates unequaled in our public reservoirs!
