Editing Murray cod (section)

====Introduced carp====
There is serious competition for food between larval/early juvenile introduced carp and larval/early juvenile native fish.<ref name=Tonkin-et-al2006/> Introduced carp dominate the fish [[fauna]]s of lowland Murray-Darling rivers; the sheer amount of [[Biomass (ecology)|biomass]] carp now take up, and the large numbers of larvae carp produce, causes serious negative effects on river ecosystems and native fish.<ref name=Tonkin-et-al2006/> Carp are the main vector of the introduced ''[[Lernaea]]'' parasite (''[[Lernaea cyprinacea]]'') and serious vectors of the introduced Asian fish tapeworm (''[[Bothriocephalus acheilognathi]]'').
