when trying to stop or solve a problem - you go to the source and stop it there..... gee if your in a dinghy and you discover water in the boat - what do you do... bale the water out or do you look for the leak and plug it before baling out the water.... ???
so paul - what seems to be happening is they are now trying to swoop on the end game because they failed to stop them coming into australia...
if none of these shrimp or fish were let into the country in the first place they wouldnt be trying to attack the end game.... no-one would be buying any of this stuff as it wouldnt be here... if this stuff was never in australia no-one would want it.... seems a bit catch 22 ish...
i would have thought securing external borders so nothing comes in would be far easier... only 2 ways stuff gets here... it walks or swims lol hahaha just kidding.... it comes by plane or by boat... and in my thinking boats take too long to get anywhere... so they are coming in by plane... dont they have xray and scanning machines, not to mention sniffer dogs etc at international airports......
Gotta remember Perth/SW water ways are not the best for all these types of fish but Up north in the warner waters some of these noxious fish will flourish.
i agree with you... temp is prob biggest determining fact for survival of any fish... maybe its time to divide WA into upper wa and lower wa that way certain species can be kept in lower wa and not in upper wa and vice versa... much like what happens state to state....
