Mother Nature strikes back in Prom seastar fight
Friday 22 June, 2012
Heavy rain at Wilsons Prom on 4 June has proven a useful ally for the incident management team trying to control the Northern Pacific Seastar infestation.
Parks Victoria Emergency and Risk Management Coordinator Mr Matt Hoskins said that 160mm fell on the Prom, which has changed the salinity of the water in the Tidal River Estuary.
"Mother Nature has helped us a lot. The recent heavy rainfall had a significant impact on the fauna of the river bed including the seastars.
"The flooding of the river, and a rapid reduction in the salinity of the water, couldn't have come at a better time. Basically, Northern Pacific Seastars like it when it's salty. Over the past few weeks, dive teams have discovered a small number of seastars that have just disintegrated in their hands," said Mr Hoskins.
Chief Ranger Helen Dixon further added that there is still a lot of work to do in ensuring the seastars have been eradicated.
“From recent dive searches, we have not found any living Northern Pacific Seastars which is incredibly encouraging in our fight against this marine pest”.
“The teams will continue to do sweeps of the estuary to remove any remaining seastars prior to the spawning season in July-August”, said Ms Dixon.
“We are reminding visitors to continue to wash and dry all equipment as they enter the river. This is vital in containing the spread. We encourage all users of Tidal River to take this precautionary approach.”
- Marine pests including the Northern Pacific Seastar are easily spread from one part of the coast to another by people and wet equipment.
- Boats, kayaks and canoes, wetsuits, fishing gear, and other equipment that remain wet can spread fertilised eggs, larvae, or small animals or plants, to new locations.
- All equipment used in marine areas should be washed in freshwater after use then thoroughly dried to reduce the risk of spreading marine pests.
- This is particularly important for people moving any equipment used in areas like Port Phillip Bay to other areas such as the Prom.
