Translocation of Fish Species

Genetic differences occur across fish populations from one part of Australia to another. Scientists have identified across Northern Australia sixteen different genetic strains of barramundi. The scientific community is, however, divided into schools of thought on the issue of translocation. Some say the ‘precautionary principle’ must be used until more research is done. Others have said their research proves they are not distinct enough to cause problems and any hybridization will actually strengthen the fishery, especially where it has been seriously depleted.

The DPI has adopted the 'precautionary approach' and currently prevents fish species to be "translocated" from one fish population area to another even though the genetic differences may be very slight. This done through the issuing of permits. A DPI permit is required for each fish stocking program (this includes each impoundment, and each species of fish).

For the MISFG this means that Gulf strain Barramundi only can be used in our stocking programs and a permit is required for each impoundment which is to be stocked. MIFSG have been able to purchase 'gulf strain' fingerlings from the hatchery in Karumba.
