| Impact Description | A study was conducted to determine effects of grass carp (Ctenopharyngodon idella) on red swamp crawfish (Procambarus clarkii) in ponds in Louisiana. The stocking rate reduced the harvestable size crawfish. After vegetation was depleted, the amounts of animal matter (mainly cladocerans, crawfish, and gyrinids) in grass carp stomachs increased greatly. |
