Shame peacock Bass in Pioneer River Mackay QLD>

South American predator fish caught in Qld

A predatory fish from South America has been caught in a Queensland river amidst fears it could wipe out native species.

Australian Associated PressJanuary 17, 20181:58pm

Central Queensland anglers say the release of a highly predatory fish from South America that could wipe out local species in just two years is an "act of environmental bastardry".

Mackay Area Fish Stocking Association (MAFSA) founding chairman Keith Day says the Peacock Bass, which was caught at the Dumbleton Weir in Mackay's Pioneer River on Monday, was almost certainly deliberately released from a private aquarium.

Mr Day says unless urgent action is taken, it could decimate the 2.5 million barramundi and sooty grunter MAFSA had cultivated in the river over the past 25 years.

"I can just see everything that we have worked for going down the gurgler," he told AAP on Wednesday.

"Why anybody would think it was a good idea is beyond me - it's an act of environmental bastardry."

The fish - which are popular pets in Australia and can be bought through online classifieds website Gumtree for as little as $20 each - are "bucket-list" catches for many recreational anglers.

They have already caused rapid devastation in areas of Brazil where they have been introduced.

The Department of Agriculture and Fisheries said in a statement the discovery was the "first confirmed capture of this species in Queensland waters" and has advised anglers to humanely kill the fish instead of releasing it.

Catchment Solutions fisheries biologist Matt Moore said authorities needed to act immediately to contain what was a potential environmental disaster.

"They are a high order apex predator - they will eat anything they can fit in their mouth," he said.

"This has the potential to affect commercial, recreational and indigenous fish stock."

He said it was vital to investigate how many of the fish were in the river and where.

"We then need to eradicate them as quickly as possible," he said.

He said electrofishing - where fish are stunned with an electric shock, then netted and sorted so pests can be killed and indigenous fish released - was one possible method.

Would be great if they could do more intensive electrofishing to remove carp and tilapia

    If Biosecurity was serious there should be a reveiw to kept species and removal of their live ownership due to this sort of infestions of natural waterways.

    fisherys know and its doubtful they are gonna last long if fished

    Fisheries biologist with Catchment Solutions Matt Moore said the fish in the photo was "definitely a peacock bass".

    The biologist says numerous local fishing and tackle shops had reported anglers catching the invasive species over the past few months, but this photo was enough proof to report it to the department and Biosecurity Queensland.

    Because of their global reputation of being a "bucket-list game fish", as Mr Moore points out, it's resulted in a number of deliberate releases into waterways they shouldn't be in across the world.

    "(The photo is) the only evidence at the moment so really, to take this further we need to undertake some community monitoring in the Pioneer River under Dumbleton Weir to confirm 100% that they exist there, what their potential distribution is and what the abundance of the fish is.

    "But it does appear at this stage that they are at the Dumbleton Weir, in the Pioneer River.

    "We're pretty confident. But as fish biologists, we have to be careful and I don't like to say 100% convinced until I have a fish in front of me... but from all reports, we're very very certain that (this is a peacock bass)."

    The investigation

    DAF confirmed they were notified of the capture of a single adult Peacock Bass on January 15, 2018 from the Dumbleton Weir in the Pioneer River.

    "Peacock Bass are not known to exist in Queensland waters. This report appears to be the first confirmed capture of this species in Queensland waters," a DAF spokesperson said.

    "DAF officers are assessing the report to gain an understanding of the extent of the incursion."

    Mackay Regional Council's Development Services director Gerard Carlyon said council had also been made aware of reports the invasive pest species Peacock bass had been found locally.

    "People need to be educated that it is not okay and often illegal to release exotic aquarium fish in our waterways," Mr Carlyon said.

    "Anyone caught intentionally releasing exotic pest species in waterways can face huge fines. We have highlighted problems with other exotics, such as tilapia, in the media in the past as they compete with and displace our native fish like barramundi."

    LNP Shadow Minister Tony Perrett said reports that four pairs had been released near Dumbleton Weir, west of Mackay, needed to be confirmed and any possible eradication actions undertaken as soon as possible.

    Mr Perrett said the South American species was responsible for widespread environmental damage in riverine systems.

    "There needs to be a full investigation and assessment of what, if anything, can be done to eradicate this pest," Mr Perrett said.

    Mr Perrett called on recreational fishers around Mackay with any knowledge of the issue to report what they knew to Biosecurity Queensland on 13 25 23.

    Report your findings

    Anglers that catch or spot Peacock Bass in the Pioneer River can report it to DAF by emailing photos to pestfish@daf.qld.gov.au.

    Ensure the details of where the fish was sighted or captured are included when reporting the pest fish.

    Once pest fish like Peacock Bass become established in large, open waterways it can be very difficult to eradicate them.

    DAF's advice is, if caught, anglers should not return it to the water. Rather, kill it humanely and dispose of it properly.
    Of course I talk to my self while fishing.. sometimes I need expert advice!

    On land line is a inanimate object. Under water it has a life of its own.

    A new cane toad.


    At least if they could handle salt water bio security could have used them to sort out the white spot problem.
    Looking forward to the next trip
