Pond-based production of Genetically Improved Farmed Tilapia (GIFT) and European Carp
is rapidly expanding in the rural areas of Papua New Guinea to the point that there are approximately 50,000 farms.
Failure to stop the spread of dangerous weeds and pests, such as the cane toad, European carp
, foxes, and the serious water weeds salvinia and cabomba--and the import and trade of hundreds of invasive species--is costing the nation $4.
APS secretary Dave Moore stated that he wants as many European carp
anglers as possible to attend as they intend to make this yearly competition a global event for carp fans worldwide.
FOUR YEARS AGO A GROUP of local anglers from the Beaudesert Region in Queensland, 60 kilometres south of Brisbane, realised that the growing numbers of European Carp in the Logan and Albert rivers were threatening the survival of the native fish species.
Taking matters into their own hands, they formed the Rathdowney Hotel Social Fishing Club, and set about harnessing the enthusiasm of local recreational anglers and directing it towards arresting the environmental degradation caused by European Carp.
The researchers have found that European carp blimp out over a period of several weeks in the presence of pike so they won't fit into the predators' mouths.
To demonstrate the more permanent change effected by European carp, Bronmark and Miner used weighted plastic curtains to bisect two small, natural ponds containing carp.
Abstract: European carp are widespread in the Murray-Darling Basin and occur in all states and the ACT.
Keywords: European carp, introduced species, feral animals, pest control, environmental degradation, Daughterless Carp Project, genetic manipulation.
At the same time local authorities were busy stocking billabongs with European carp.
Sampling by NSW Fisheries in 1993 yielded 90% European carp and no valuable native species such as golden or silver perch, or Murray cod.
Similarly, no substantial differences exist between the karyotypes of European carps
and some Chinese subspecies (Zhan & Song 1980; Rab 1995).
