I was re-reading this and thought I'd respond, just because the stuffing hilarious bit, hah ha,,, your comment implies that there is hidden agenda, at the same time I do know that your pro-native, so to speak,, there is no hidden agenda I can assure you,,, I just look around some places in the world with water bodies scarily stuffed right up,, where humans impact hard,, river systems back in time, (at time of human settlements through out the world forming claimed continents),,,,, where the primary and very diverse resources supported the beginning of human population,,, typically, humans thrash it do death as they colonise, spread and sprawl,,, ever so seeming to follow the lush bush and nature and ripping it out,, these days the whole lot is bull dosed and peeled back to put the underground infrastructure in and land fill back over and sometimes terraced."...everyone now only looks after themselves."
Like guys that own expensive koi arguing against the use of the virus... thats stuffing hilarious!
People washing their cars in Balga, as well as fertilizing and what ever else in the late 90's has excess of these chemical waiste delivered into the ground,, which actually heads towards the swan river in a underground artery water flow, then makes it out IN the river.
People just don't know this,,,
If Koi aren't actually taking anything away from the natives AS IS IN TODAYS STATE of condition, then they can only be a benefit, buy filling the missing gaps in the ecosystem that works better with rather than without.
You all go on about the predatory skills and sheer crazy savagery,,, if you know koi, they are week as piss,, no one can tell me the koi disrupt native breeding grounds, they may have, but not to impact.
The natives wouldn't give them a chance,,, the native species were well in trouble before koi got about.
There were badly effected inland systems in the past effected buy koi or carp, (same thing), but a lot of these were subject to drying out.
See, no hidden agenda,,,, so should I feel insulted ??? Many people likely would,, but me, nah all good,,, just a response, that's all
