Ponds with a Purpose: Fishery Management on Working Lands | Wild Ag #555

Conestoga Reservoir accumulated nearly one million cubic yards of sediment, creating a potential $15 million restoration bill.

1. Natural Resources University presents Wild Ag #555 on fishery management for ponds and reservoirs embedded in Nebraska's agricultural landscapes.\n2. Dr. Andrew Little and Nate Pflueger host Jeff Jackson, a Nebraska Game and Parks fisheries biologist who has managed aquatic habitat projects for about five years.\n3. Jackson argues that water quality is the foundation of a successful small-lake fishery, while bass density controls bluegill and crappie balance.\n4. He explains that low bass density can leave bluegill and crappie stunted because predators no longer effectively regulate their numbers.\n5. Small ponds can remain self-sustaining after initial stocking, but channel catfish generally require restocking at roughly 8 to 10 inches to survive bass predation.\n6. Jackson's study of 7-, 9-, and 11-inch channel catfish found almost no survival for the 7-inch fish and about three times greater survival after they passed the 8-inch threshold.\n7. Common carp, shad, and white perch threaten southeastern Nebraska fisheries, with carp stirring lake bottoms and shad potentially occupying 80% of a lake's biomass.\n8. Jackson says invasive plants such as Eurasian milfoil and curly-leaf pondweed can spread on boat trailers, take over fishing areas, and contribute to fish kills when dense vegetation dies.\n9. Conestoga Reservoir accumulated nearly one million cubic yards of sediment across 200 acres, making full restoration at $10 to $15 per cubic yard an estimated $15 million project.\n10. Landowners interested in pond fisheries, buffers, sediment control, and aquatic habitat management.

As heard by us

A grounded episode on how sediment and limited conservation dollars shape reservoir fisheries in ag-dominated landscapes.

Reservoirs can look like permanent fixtures in an ag-dominated landscape, but this episode keeps its focus on how much their fisheries depend on what comes in from the surrounding land.
