Hopefully the media will start picking up on this;

 

https://www.research..._to_biosecurity

 

https://thefishvet.c...nternationally/

 

 

This article outlines my exact concerns about the mass amount of virus that would be in the water, the evolutionary potential and switching hosts.

 

I also like how they compare the reproductive rates of rabbits to carp, dealing with an animal that releases millions of eggs in a spawn.

Actually the article said there is no evidence at all any where on the planet ever in recorded history of the virus infecting a fish that isn't a poxy carp. Sure the writer said we're scared it could... That's not science, it's the writers theory of what could go wrong.
None of the references support this fear.

I'll admit that the mass of dead carp will be a problem. The plan isn't to infect the whole river at once and see what happens though. Release points will be monitored and the vast majority of dead carp removed from the river.
Could it cause a system crash? Maybe locally but Who cares... Unless something decisive is done about carp the MDB waters will be rooted anyway!

There's no denying that there will be spawning but that system has some pretty awesome predators that, given half a chance will keep carp under control.

The arguments for and against haven't changed and the article provided does absolutely nothing to further anyone's knowledge of the subject. It's quite funny actually because it's written very poorly but the writer has tried to make it look respectable by referencing... Fail!

i didnt think so - just reinforced what everybody has been saying before.... although now adding globally we are being slammed for potentially introducing this virus on purpose... carp are a huge food source for the world and countries that depend on this arent happy..... bout time someone considered harvesting carp and sending them to other countries for food if we dont want to eat them.... with fukishima spewing dangerous waste into pacific ocean it wont be long till ocean caught fish wont be considered safe to eat anymore... making mrd carp a safer alternative :) ????

 

we all have our opinion - so i'll agree to disagree with bunnies that want to introduce pox virus into australia...

Malawiman their use of logic and common sense to determine risk is not a fail. Doctors once laughed at the idea of properly washing their hands between surgeries, they cross infected and lost countless patients, despite Dr Ignaz Semmelweis arguing the benefits of hand hygiene, other doctors refused to do it because there was no scientific evidence at the time to prove that washing their hands would help patients prognosis, so there is nothing wrong with working on logic and a hunch until science catches up.

logic/common sense dictated the earth was flat until science caught up...

Word of the day: Epistemology.

Thinking the earth was flat while watching the rounded sun go over the horizon might be considered common sense and logical to you, but I would have to disagree. Common sense and logic was on the side proposing the earth was not flat, and it was probably people like you who argued against them, because again your on the wrong side of the argument.

 

If I can get a water supply loaded with the virus, will you be willing to drink it, bathe in it, and use it in your aquariums for the next 30 years?

I'm not saying flat does or doesn't make sense... but it was entirely wrong. My thoughts on it are not an issue. The scientific community and the world believed based on their perception of reality that the world was flat.

Like wise... without scientific knowledge of bacteria, hand washing would have seemed silly.

And so, common sense isn't always a great approach to a problem.

I would say yes if I thought it would fix a bigger issue... Your hypothetical situation doesn't come with a benefit. It's apples and oranges.
EHNV is already present in the MDB... I don't hear people freaking out about the viruses ability to jump hosts and destroy a mans spleen.
So there is already fish virus present and yet it doesn't cause issues to water supply, tourism,etc... What's the difference? If anything EHNV is worse because it does affect native fish too.

Species known to be susceptible to EHN are listed below.

 

Common name Scientific name

 

Macquarie perch Macquaria australasica

Mosquito fish Gambusia affinis

Mountain galaxias Galaxias olidus

Murray cod Maccullochella peelii peelii

Rainbow trout Oncorhynchus mykiss

Redfin perch or European perch Perca fluviatilis

Silver perch Bidyanus bidyanus

 

gee aquaponics will suffer....  seeing gambusia are susceptible to this disease it is easily spread... wonder do we already have ehn in WA ???

Im not scared about what we know about viruses, what worries me is what we don't know yet, and thats a lot. Thats why we shouldn't be doing this, plus the fact that the people pushing this idea have admitted it wont work in the long term anyway. 

 

Believe it or not there are fish experts who think this idea is insane, they cant speak out, because many of them work for Government, and they don't want to jeopardise their incomes.

and such it goes back to the dollar - got enough $$$ and pay a scientist to prove whatever you want so it keeps you in a job :)

No No No, that never happens, BTW is red wine and chocolate good for you or bad for you at the moment? it changes from week to week depending on who's paying the scientists to do the report.

Yes, according to available dicuments, the Pemberton Trout hatchery 'had' it - but after the Fisheries department sold it to a private group, it miraculously dissappeared..... by the way, this was after a new test was used to try to (not) find it.....

Guess how many (hundreds of thousands) of trout get released into WA rivers every year....?
