Thanks mate,

Much appreciated, it is a bit of an uphill battle at times but I am seeing more positive feedback and some "private mails" from closet catch and release Aussies, so hopefully I can keep changing Australias opinions even if it is one angler at a time. :P

Tell me luke , cos i've seen it mentioned on another thread too , but why exactly do the catch & release Carpers in Aus have to keep a low profile ?

What is seen as so bad about returning these beautiful fish by the australians ?

Basically mate, the government has done an awesome job of blaming all evils on "european carp" here is an excerpt from the new south wales DPI



What are the impacts of carp?

Because of their adaptability, carp have been very successful in their colonisation of new environments.

Carp are widely believed to have detrimental effects on native aquatic plants, animals and general river health, particularly through their destructive feeding habits.

Carp are often found in degraded areas, although it is not clear whether they cause the degradation or are simply able to survive in degraded areas where native fish cannot, or where natives have otherwise been eliminated. While in some cases carp have probably been blamed for degradation that is actually the result of human activities, it is clear that carp can have major impacts.

Some of the probable impacts of carp are outlined below.

Reduced water quality: Carp contribute to poor water quality by uprooting vegetation and stirring up sediments during feeding, leading to increased turbidity.

This in turn reduces light penetration, which can make it difficult for native fish that rely on sight to feed. Reduced light can also decrease plant growth, and suspended sediments can smother plants and clog fishes' gills.

The effects of carp on water quality are well documented; however, poor catchment management practices probably have a more substantial effect.

Algal blooms: There have been suggestions that carp may increase the likelihood of algal blooms by preying on animals that eat algae, stirring up nutrients trapped in bottom sediments, damaging aquatic plants, and reducing plant growth via greater turbidity.
However, carp densities may have to be very high to significantly increase the likelihood of an algal bloom.

Erosion: Carp feeding habits can undermine river banks leading to the collapse of banks and vegetation.

However, clearing of riparian vegetation, changes to river flows through river regulation, and trampling by livestock are more important factors in bank erosion. Restoration of riparian vegetation can minimise the risk of damage by carp.

Impacts on invertebrates: Juvenile carp feed mainly on zooplankton, but start consuming larger (macro-) invertebrates once they reach around 15 cm in length. There is strong evidence that carp impact on native invertebrates in still waters, but only anecdotal evidence for their impacts in running waters.

Impacts on aquatic plants: Carp have significant effects on native aquatic plants both through direct grazing and through uprooting plants while feeding, leading to a reduction in plant density and biomass. Soft-leaved, shallow-rooted and submerged plants are most likely to be affected.

Disease: In other parts of the world, carp have been associated with the distribution of a range of parasites and fungal, bacterial and viral diseases. However, there have been few disease outbreaks attributed to carp in Australia.

Reduction in native fish numbers: The effects of carp on native fish are not well understood. Negative impacts of carp are thought to include competition for food and habitats and effects on recruitment (population replenishment). However, many native species (such as golden perch, Murray cod, silver perch and freshwater catfish) had experienced well-documented declines even before carp became widespread.

The feeding methods of carp can uproot aquatic vegetation and muddy the water. Carp have been blamed for damaging freshwater habitats and causing decreases in light penetration, dissolved oxygen and plant material. These changes may have affected native fish.


Blamed? thought to? not well understood? Associated? Anecdotal? Suggestions? widely believed? Probable????


This is the propaganda that the aussie government have fed generations of anglers who have without question accepted that the above is gospel and dismissed the FACT that there is literally NO documented, factual, scientific study that proves any of the above. rather there are studies that show that man has made consistently poor choices in his management of the waterways which has lead to some seriously polluted waterways that have in turn killed all the natives, yet as the carp are the last man standing the government would rather blame the carp than invest in cleaning up the damage that its management and industry has created.


It's not so bad in NSW as it is legal to return them, but in  some states it is illegal (unenforceable law though as the evidence has swum away and hence nobody has ever been prosecuted) hence people go out to kill as many as they can believing that they are doing the environment a favour (yet ironically usually leave a heap of cr#p behind in the shape of beer bottles, sweetcorn tins, fag butts, food packaging, discarded line, hooks  etc etc. it is literally the most ridiculous thing you have ever seen, that these guys are utter eco vandals whilst on the bank and yet seem to gain great pleasure in killing an innocent creature and leaving it rotting on the bak in the belief that they have done the environment a favour.


Most fishermen stay low key as there have been cases in some states where established carp waters have been wiped out by these idiots and basically left as lifeless holes in the ground because someone let on where they were fishing. Thats why I never disclose exactly where I am. If someone is interested the normally contact me and I or another session carper meet them and get to know them befor ereally sharing and serious info. Sad state of affairs, but it is still a land with more free fishing than any body could fish in their lifetime :wink:

Its a crying shame and that stuff you c& pasted is probably some of the biggest pile of faeces that i've ever read in this day and age .


How can a government that has its anti-terrorism and immigration laws SO right advocate issueing that sort of tripe ?

What you need to understand is that for years the Australian government and industry has treated the waterways like cr#p, They have dammed waterways, sold the rights to use the water and dumped heaps of toxic cack in there for the last 130 years, which has decimated the indigenous species. For instance a lot of the indigenous fish need to migrate to breed, thats pretty hard if there is now a huge Dam in the way. Agriculture has brought the water rights to go on the land, which in turn washes nitrogen rich fertilizers etc straight in to the waterways, which now have virtually no flow due to the amount of water being used upstream or held back by dams.


Obviously though it is cheaper (and politically less damaging) to blame a fish, than admit that you've ballsed the waterways up. It is also made much easier when you have scientists that are on government grants doing "research in to how to eradicate carp" note research in to how to erradicate them, not in to whether they actually have a negative effect or not, so far they have come up with such great ideas as genetically engineering carp that will only spawn male fish, and also then suggesting that they release KHV in to the waterways as the "believe" that it will only affect the carp. Surprisingly the scientists that are on government funded research projects such as the above aren't in any hurry to question why they are desperate to get rid of something that actually probably isn't the issue.


Fact is that even if they managed to eradicate carp from the waterways, native fish will not return, they simply cannot tolerate the polluted waterways or breed, hence we would then end up with barren waterways full of eels and turtles which is pretty much the only other thing that survives in there currently.


It's a very sorry state of affairs but thankfully NSW has softened its stance considerably in recent years and has even "downgraded" the carps "noxious pest" status from must kill, to we'd prefer you to kill it.


There is also a very different attitude to fishing in general in Australia, Aussies "fish for a feed" as in they want to eat what they catch. I used to get upset about them killing carp and then another angler summed up the Aussie attitude with this statement


Luke, if they can eat it its dinner so it's dead! If it's to small to eat, they use it as bait, so its dead! If it can't be eaten or used for bait, it's a cr#p fish and it's dead. Australians as a rule treat everything the same, they don't single them out, if they catch it, IT'S DEAD!

I dont even lnow what to say after that :(

Tv programmes over here would have us believe the aussies have hunted the ( for example ) Sawfish to the point of extinction and its qaterways have now been taken over by freshwater Bull Sharks .

Not a mention about Carp .




Still , good to hear your doing your "bit" as it were.


Info like you have just provided on here may help albeit little by little .

I wish you well Luke :wink:
