Its been 25 years since I fished the Murry River but even then the bloody carp had ruines the place. I can remember fishing in my early teens and the water was crystal clear with many water plants and great fishing. The refin were up to 5 kg and cod a plenty. Wonderful country then. Now, thanks to dipshit pollies, cotton farmers, vermin, bogan campers and land clearing our once magnificent waterways are just drainage canals. The carp have to be cleaned out asap. Hopefully the CSRIO can get it sorted. Lucky to have such a good organisation as the dipshit pollies keep cutting their funding.

Heres some info
2. Will CyHV-3 be effective as a biocontrol agent?

CyHV-3 first appeared in Israel in 1998 and quickly spread throughout the world, killing-off common and koi carp. Ironically carp are farmed in many countries and are an important food source. So, while CyHV-3 has devastated carp farming, the overseas experience has demonstrated how it could be used successfully as a biocontrol agent here.
Testing of CyHV-3 in the high-security Fish Diseases Laboratory at our Australian Animal Health Laboratory (AAHL), in Geelong, Victoria, has proven that the same virus does in fact kill Australian carp, and it kills them fast.
The flip side is our rigorous testing to ensure that the virus won’t affect native Australian or important introduced species of fish. It has been shown to pose no danger to 13 native species such as Murray cod, various species of perch, eel and catfish, as well as a crustacean (yabbies) and a non-native fish species, the rainbow trout. Our work has shown that there are no clinical or pathological changes in these non-target animals, nor is there any evidence that the virus multiplies in these species.
Chickens, mice, frogs, turtles and water dragons have also been tested as representatives of a wider community of birds, mammals, amphibians and reptiles. Again the virus has shown no effect on them which also makes us confident that it won’t affect that other major group of mammals – humans.
Based on lessons learnt from past use of viral biocontrol agents for invasive vertebrates, we expect that CyHV-3 will have the greatest impact in the first couple of years after release. After that, its effectiveness may be diminished, but not lost, as virus and host adapt to each other.
Therefore, we need an integrated pest management program that utilizes other methods to complement our virus. These include new broad-scale technologies such as ‘daughterless’ technology to create male-only populations, as well as traditional regional methods such as trapping, the commercial collection of carp, and controlling access of carp to breeding grounds.
