Carp Virus

And not a single source was referenced.

Well the reason trout are prevelant is because they live in a completely different environment(streams) to carp and cod. Although other introduced species are bad, carp are the worst for our environment.

One virus at a time?

I totally agree Smokey , , , ,

One Bug at a time

Cheers for reading my post...but your one liner responses haven't really contributed any value to this thread.

And a bunch of fantasies about freshwater carp charters have?

If there was any money to be made out of fishing for them we’d be doing more than turning them into liquid fertiliser. If there was any widespread attitude that they were a prestigious sports fish the banks of half the creeks and drains in the country would look like Mornington in snapper raping season.

Freshwater carp charters?? Where was that part of my suggestion. Again, sorry mate, no value added to the conversation.

Carp (Cyprinus carpio) have been in Australia for over 100 years and are now established in all states and territories, except the Northern Territory.

Carp completely dominate freshwater fish communities in southeastern Australia – in many areas they comprise a significant proportion of fish biomass, sometimes exceeding 80% or 350 kilograms per hectare in some parts of the Murray-Darling Basin.

Carp impacts are felt environmentally, economically and socially. They affect water quality, native fish, fishing and irrigation. We have funded an independent study to rigorously and transparently calculate the impact on Australia's economy.

The key impacts of carp are as follows:

Carp are ‘ecosystem engineers’ – modifying waterways as they suck up mud. They stir up silt and muddy the water, blocking sunlight to aquatic vegetation, and impacting plankton, aquatic invertebrates, waterbirds, and native fish.

Carp are 'water wreckers' – their feeding activity lowers water quality and increases nutrient levels. They also impact zooplankton, which normally feed on microscopic planktonic algae. When combined, these factors can contribute to blue-green algal blooms that impact recreational use of waterways (i.e., swimming, skiing etc.).

Carp are 'resource hogs' – they take valuable food away from native fish. This particularly impacts smaller native fish species, but also larger species higher up the food chain. Some native species, like Murray cod, eat small carp, but this is not their natural food source.

Carp are 'trash fish' – getting in the way of natives. People go fishing to spend time with friends, get outdoors and maybe catch a few fish. Catching carp can be fun, but most anglers want to catch natives. Carp currently undermine the recreational fishing industry, worth billions of dollars.

The image below shows the benefits of removing carp from an area. This wetland dried out, carp were prevented from returning using a screen and the system filled again naturally. The improved water clarity is clear to see.

Carp have been identified as a priority pest species, both in Australia and internationally. The International Union for Conservation of Nature has named carp one of the world’s most invasive fish species.

A recent national survey reported that the public perceive carp as the fourth most significant vertebrate pest in Australia (after cane toads, feral cats and rabbits). For at least the last two decades, there has been a shared desire among natural resource management agencies and communities for control programs to reduce these impacts.

Australia is working hard to rehabilitate rivers and wetlands. Significant investment, in fishways, environmental watering and other measures, is being compromised by carp.

It’s time to get carp out of the way, so our native fish have a chance to compete.

There was no value in your original post, and no, carp are not here to stay and are not recognised by anyone as a prestigious sport fish.

[OkeyDokey]

Sorry guys, still nothing of value here. I think you're missing my point that increasing managed fisheries can share the biomass problem across those sustainably funded resources, which free's up Govt resources to focus on carp removal in the major basins AND infrastructure to improve water quality for the long term.

You gotta stop taking an emotive stand and look at the bigger picture. I don't need to provide any other evidence than point to the UK and Europe and how it's managed there.

[ronan]

I think you're the one that's actually missing the point here. You have to remember that carp believe it or not are introduced here, whereas in Europe, they are native. The carp fishery in Europe is managed well and is popular because they are a native fish, and are not detrimental to the environment there because it's where they come from. They are part of the natural ecosystem there, however in Australia they are not. They out-compete natives for valuable food and stir up silt, in turn creating a lower water quality which once again makes everything harder for native fish. Boonanza's post above quoting Victorian Fisheries sums this up.
