Stella Posted February 5, 2013 Report Share Posted February 5, 2013 Does anyone know of any sites in Taranaki with koi or gambusia ('mosquitofish', or anything that looks like a wild guppy) I have just started a fish surveying contract for DOC Taranaki, and the pest fish component is looking for koi and gambusia. There are a few known sites in the area, so at this stage it is still possible to eradicate them from most of the area, which is rather exciting. These fish are pests because koi can change the habitat in lakes and streams from plant-dominated to muddy or algae-dominated, which has big effects on the food-chain, and gambusia are aggressive little sods and highly invasive - they spread easily and rapidly. It is illegal to possess either of these species, but there is no risk to anyone coming forward - we just want to get rid of them. Quote Link to comment Share on other sites More sharing options...
