Ponto-Caspian gammarids: Biological control using predatory fish
Overall effectiveness category No evidence found (no assessment)
Number of studies: 0
Background information and definitions
Predatory fish could potentially be used to biologically control invasive shrimp. A study from Lake Constance, which borders Germany, Switzerland and Austria, found that the arrival of the invasive Ponto-Caspian killer shrimp Dikerogammarus villosus led to several fish species in the lake changing their diet (Eckmann et al. 2008). Burbot Lota lota, European eel Anguilla anguilla and Eurasian perch Perca fluviatilis all fed on the killer shrimp (Eckmann et al. 2008).
