Post subject:  New high risk threat to WA waterways

Fisheries have recently discovered what appears to be a huge threat to WA native waterways.
They have been raiding fish shops and peoples houses to capture and destroy all of these animals.
There must have been some research into these that causes massive risks to the environment, obviously on a vastly larger scale than anything you can imagine.
When raiding your house atleast 3 people will rock up, treat you like a criminal, and video tape everything.

So what is this highly dangerous creature?
The Cherry Shrimp

This scary creature reaches a max size of about 20mm or 20 000 000 nano meters (it sounds bigger that way :shifty: )
They are highly dangerous to local fish populations, they probably reach as high as krill on the food chain.
And are actually really good parents to other fish eggs, if the parents don't eat them, as they clean and remove fungus eggs stopping it spreading.

So if you have purchased or sold any of these vicious scary creatures, beware, they may come knocking.
And if you happen to have any other form of shrimp as well, including natives, they will seize and destroy those too if you haven't completed a translocation permit for them.
It doesn't matter if they are kept for ornamental purposes only, apparently fisheries want translocation permits for all fish now.

Currently being discussed here

So watch out next time you swim in a fresh water lake around WA, you may get attacked by some deadly thumbnail sized shrimp.

Everyone who has complained about how easy ornamental fish keepers have it... the times are changing

Congrats Dept of Fisheries, you truly have paid yourselves off by finding this biosecurity threat.

Andrew

ps. I no longer keep these creatures, their pure evilness forced me to give them away to people for free, I still suffer from the nightmares

Have some sympathies for the above.. especially in relation to the approach being taken by Fisheries...

But a quick bit of research suggests that the shrimp is an illegally introduced Taiwanese shrimp... capable of growing to 4cm....

And a prolific breeder..... so prolific, that another quick search... showed pages of people in WA trying to sell them....

My concern would be... if people can't manage their breeding... and off-load them.... would they be likely to dump them into water-ways...

I'm sure yourself, and other responsible members of the aquaria community wouldn't do so Werdna....

But there's a certain historical basis that suggests that many in the aquaria community... don't have a particularly caring, or thoughtful approach to bio-security...

Given that these shrimp appear to be almost the "Tilapia" of the shrimp world... I can understand that Fisheries might have a "bio-security" concern....

But they need to approach it differently... by consultation... and education....

I saw the suggestion on the forum.... that people adopt the same approach with Fisheries... that members here did with regards to trout/silver perch..... file translocation permits... by the bucket load... :wink:

Ha.
The site is down due to a forum upgrade.
Should be back online tonight :)
You'll see why in the venting thread, when it is back online...


RoO, yes they are prolific breeder, however there has always been high demand for them.
People aren't going to dump them into rivers when they can sell them

Labelling most in the aquaria community as uncaring towards biosecurity is a bit unfair IMO.
We have been working with Fisheries and the Swan River Trust on education about this problem.
Starting with posters and hopefully a print on the side of the take home plastic fish bags.

Unfortunately it was some idiot aquarium keeper who released Pearl Cichlid (G Braziliensis) in our waterways, but putting everyone in the same basket is not fair.
Developers here are still adding Koi to park ponds to give people something to feed.

And history shows that one of the worst for introducing fish that have large biosecurity risks are Fisheries themselves.

My query is why Cherry Shrimp?
They have been here since atleast 2006 and there has never been a case of them in the wild.
They cant handle our winter temps.
They don't interbreed.
Of all the fish out there, what makes these such a high risk?
