The Best Monitoring Method: The Best Monitoring Method Fishing
Questions To Ask Yourself: Questions To Ask Yourself Is the average size of bluegill declining?
Is the largest size bluegill you catch getting smaller?
Do you catch fewer big fish?
Are bass being caught less frequently?
Are crappie, carp, or other non-stocked fish being caught?

Three Reasons For Poor FishingQuality: Three Reasons For Poor Fishing Quality Wrong kinds of fish
Wrong size of fish
Wrong number of fish
Pond Management Is A Balancing Act: Pond Management Is A Balancing Act A balanced pond fishery can be established with the initial stocking. Maintaining that balance requires the pond owner to manage the harvest.
100 Bass and 1,000 Bream per Acre
Largemouth Bass Mortality: Largemouth Bass Mortality
Managing The Harvest: Managing The Harvest Catch and Release
Bag Limits
Size Limits
Education
Managing Largemouth Bass: Managing Largemouth Bass Do not harvest bass for two years after initial stocking
Minimum size limit of 14 inches
Remove no more than 20 to 25 bass per surface acre each year (after the first two years)
Be conservative
Common Causes Of Muddy Ponds And Their Solutions: Common Causes Of Muddy Ponds And Their Solutions Soil erosion
Abundance of common carp and bullheads
Wave action
Livestock
Suspended clay particles Buffer zone of grass
Eradication : chemical or drain pond
Riprap or vegetation
Fencing
Liming, Hay, Gypsum
Pond Fertilization: Pond Fertilization 50 lbs per Acre per Month in Spring
Lime requirement must be met
Benefits: increase fish production and reduce aquatic weeds
Risks:
Does not work when aquatic weeds are present
Water flow through pond removes nutrients
Cannot control weed growth in shallow ponds
Liming is required in most Southern ponds
Fish Kills Due to Low Oxygen: Fish Kills Due to Low Oxygen Cloudy weather for several days
Rapid plant die-offs resulting from:
Change in algal species
Intense sunlight
High winds
Presence of herbicide
Oxygen Management: Oxygen Management Keep pond full
Plan to aerate the pond (1 hp per Acre)
Pumps, aerators, stirrers, fountains, air blowers, diffusers
Create a “sanctuary”area
Potassium permanganate
Aquatic Weed Control: Aquatic Weed Control Treatment the weed then add Triploid Grass Carp
Use 14 inch Grass Carp if Bass are already stocked
Types of control
Physical – Pond design or weed removal
Chemical - Herbicide
Biological – Grass Carp
Common Aquatic Herbicides: Common Aquatic Herbicides Diquat (Reward)
2,4 – D
Glyphosate (Rodeo)
Copper (Copper sulfate, Cutrine, Earthtech)
Endothal (Aquathol)
Sonar
Correcting Poor Fishing: Correcting Poor Fishing Eradication of all fish species is recommended if your pond contains a poor mix of fish species or is dominated by over-crowded, slow-growing bluegills
Choices:
Drain pond
Chemically treat
Stunted Bass: Stunted Bass Causes:
Underfishing for Bass
No structure for Bream
Disease (tapeworm) in Bass
Cure
Balance fishing and record catch
Add Christmas trees or fish habitat
Control wading birds stock red-ear
Fish Attractors: Fish Attractors May be useful if pond has limited cover
Will not significantly increase pond productivity , simply concentrates fish
Recommended materials include brush, Christmas trees or any wood
Anchor to the bottom
Feeding Fish: Feeding Fish Not recommended for most pond owners - not needed in a balanced system
Okay if Catfish have been stocked
Not a solution for undersized fish
Pattern Of Fishing In An Unmanaged Pond: Pattern Of Fishing In An Unmanaged Pond The pond is built and stocked with fish
Fishing begins one or two years later
Three to five years after construction, fishing is excellent
Fishing declines after six or seven years and remains poor
Why Does Fishing Decline: Why Does Fishing Decline Aquatic Plant Growth
makes capturing prey more difficult
increases the chances of fish kills due to plant die-offs
Selective Fishing
Only Bass are caught
Only Large Bream are removed
Pond Renovation: Pond Renovation Recommended for ponds with:
Stunted fish populations
Too many problem fish
Excessive weed growth and decomposing organic material
