Flies that are used for native species such as Bass, Murray cod, Saratoga and Barramundi are all exciting native species to fish for as they all surface strike in a spectacular fashion.
Many of these native species flies have large hooks up to 6/0 and tied in both floating patterns and Sub surface to heavily weighted flies to dredge the depths.
Some of the materials used on the native species flies are long streamer feathers, synthetic fibres, foam popper heads, foam bodies and large stick on eyes.
European Carp an introduced species so a non native species and are are concidered an invasive species, often blamed for any environmental damage in systems where they occur, they do in fact cause considerable damage.
Some native species, notably Murray cod, have learned to feed on carp, young carp and other invasive species form an important part of their food supply at certain times of the year.
European perch/redfin are a non native species. Redfin are also introduced species and a invasive species, being an active predator of other fish and also host to a viral disease known to effect native fish species.
Murry Cod are an endemic species mostly found in the Murry Darling systems while Baramundi is a endemic species mostly found on the far north coastal regions of Australia.
Note: An introduced species might become invasive if it can outcompete native species for resources such as nutrients, light, physical space, water, or food. If these species evolved under great competition or predation, then the new environment may host fewer able competitors, allowing the invader to proliferate quickly.
