This is the stocking range we have used successfully. Higher stocking rates may be possible with this management method but are unproven at this time. Bighead polyculture did not directly affect catfish production in the Langston experiments. However, plankton populations and water quality parameters were more stable in the bighead ponds. Fathead minnows should provide polyculture benefits similar to those from bighead carp.
Fatheads feed on periphyton, zooplankton, insects, waste feed and detritus.
This behavior will help to moderate plankton blooms and organic waste loading. Fatheads can also provide additional food for catfish and extra farm income, if bait markets are established. Four, hardwood loading pallets per acre will provide adequate spawning structures for the fatheads. Feed must provide complete nutrition with maximum conversion efficiency. Extra protein is needed to ensure rapid growth without reducing water quality.
