Background information and definitions
Draining invaded waterbodies is a proven tool for reducing the population size of fish such as topmouth gudgeon Pseudorasbora parva, potentially used in combination with gill netting and electrofishing (Copp et al. 2007), or other habitat modifications such as pH alteration (Britton et al. 2008). It is therefore possible that it could also prove a useful tool for reducing populations of invasive gobies.
Potentially negative side effects of draining waterbodies on native species need to be carefully managed. However, it is possible that eradicating invasive gobies from a waterbody would facilitate an increase in the diversity and richness of native species, as found when invasive largemouth bass Micropterus salmoides were eradicated through pond drying in a field study in Japan (Tsunoda et al. 2010).
