A ROGUE fish tank is likely behind the outbreak of a noxious and smelly weed outbreak at Swimming Creek, Nambucca Heads.
Nambucca Shire Council this week advised that the highly invasive aquatic noxious weed known as Salvinia (Salvinia molesta) has infested the waterway.
The infestation is suspected to have been introduced through the illegal dumping of an aquarium above the existing infestation.
“Salvinia is currently declared as a Class 3 Noxious Weed that must be fully and continuously suppressed and destroyed under the Noxious Weed Act,” council’s noxious weeds inspector, Tim Woodward said.
“Salvinia is a free floating aquatic fern that can double in size in less than three days with optimal nutrient and temperature conditions.”
Mr Woodward said authroities had initially hoped that Swimming Creek would naturally open to the ocean and that tidal inundation would increase the salinity levels within the creek, killing off the salvinia by natural means – but that hasn’t worked.
So council now plans to poison the weed.
“Council has received multiple complaints from adjoining residences and the nearby tourist park regarding the obnoxious odour emanating from the stagnant water, as a result of the salvinia infestation,” council’s assistant general manager Engineering Services, Paul Gallagher said
“Council has consulted with various stakeholder groups, including the NSW DPI state aquatic weeds project officer, and resolved that the most effective and efficient management strategy will be to utilise the approved aquatic glyphosate based herbicides to control this invasive aquatic weed species.”
Council intends to apply the herbicide and signs will be erected when spraying is being performed.
