One sentence ruins your entire arguement! March 21, 2006 11:31 AM

Here are some adverse effects feral animals are accused of, but bear in mind the comments that very little good research has been done on the actual extent and severity of these problems.  [ send green star]  [ accepted]

Mosquito Fish? June 22, 2006 12:18 PM

I remember reading about a live-bearing fish that looks like a guppy & is called a mosquito fish since it eats mosquitoes, "but ironically they are not very good at it!" according to a link I googled up about them for you to click on. http://www.doc.govt.nz/Conservation/002~Animal-Pests/Pest-Fish-(Freshwater)/Gambusia-(formerly-known-as-mosquito-fish).asp This fish, native to the Gulf of Mexico, was introduced to New Zealand to control mosquitoes. According to the article I remember reading this fish (Gambusia affinis) was spread to every continent of the world and eats native fish and tadpoles, which do a better job of eating mosquitoes than the Gambusia. There must still be a lot of people who purchase or distribute these fish for free to use here in the US because I found a lot of sites for this purpose before I found the site I just gave you. Good reason not to release a nonnative species to a new environment. paula  [ send green star]  [ accepted]

That's fairly typical of many feral pests. Our worst - the cane toad - was introduced to control the cane beetle, which it doesn't actually eat.  [ send green star]
 
Ferrets and Stoats were introduced to New Zealand to hunt Rabbits June 22, 2006 5:58 PM

The rabbits were a feral pest

Now NZ has feral ferrets and stoats.

In NZ the Australian Possum - feral pest, [in Australia it's protected]

Almost every mammal in NZ is an introduced species - many of them are NOW "Feral Pests" if not properly controlled......

Feral Birds include the Magpie and Indian Mynah [there are more]

There are also becoming feral fish species that ruin waterways and lakes and ponds.

IN AOTEAROA/NEW ZEALAND there are also feral plants [weeds] which include: wilding pines, gorse, broom, lupins, willows etc........

It's not protected everywhere here - they still poison them in Tasmania. I think the protection should be removed. Just because they are native doesn't mean they aren't a pest.  [ send green star]
