Caring for Marine Reserves

What can you do to help? 

The continued survival of the marine environment depends on your help. Please follow our motto 'Don't Rubbish Our Sea', and look after our coast.

It is important to minimise the impact of human activity:

  • Try to avoid anchoring boats within marine reserves. If you must anchor, do so on kelp covered reef or, preferably sand. Avoid anchoring on sponge gardens or seagrass.
  • Stow your rubbish, don't throw it. Plastic, ropes and fishing tackle can injure and kill marine life. Dumping rubbish at sea is illegal.
  • Please take care with liquid wastes such as detergents, fuel and oil, and sewage. These can be toxic to marine life.
  • Try to walk around plants and animals along the shoreline.
  • Leave shells where you find them so that they can become homes for other creatures.

Marine Pests - Prevent the Spread

One of the greatest threats to our oceans and our marine reserves is the introduction of marine pests aboard boats. Before you travel to any new area, as part of your normal checks:
- Clean and anti-foul your boat and dinghy hulls
- Clean all seawater systems
- Clean and dry your boating equipment, dive gear and fishing gear
- Never discharge bilge water into the marine reserve as it can contain marine pests

Vessel Cleaning

Why clean your hull?
Marine pests love a dirty boat bottom. They can take hold in the fouling fuzz and hitch-hike to new locations, where they can seriously affect marine habitats, food chains, fish stocks, recreational activities and aquaculture.

When should you clean it?
Slip your vessel for a thorough clean and reapplication of antifouling paint annually. Many boaties find a good thorough coat lasts longer than this, with their more frequent maintenance being a water blast. The aim is to have your vessel carrying no more than a light slime layer at any time. At a minimum, before leaving home check that your boat is free of bio-fouling growth such as seaweeds, barnacles, mussels and oysters.

How do you clean it?
Once your vessel is on a hardstand or slipway, dislodge all plants and animals and dispose of them in a bin that will go to a land-based rubbish tip.
Thoroughly water blast or hose and brush down the areas of the vessel that are normally under the waterline. Pay particular attention to the following areas:
- the hull, keel and stabilisers
- intakes and outlets
- propellers and shafts
- rudders, rudder shafts and casings, rudder recesses
- anchors, anchor chains and anchor wells.

What about your dinghy?
Dinghies should be drained of water and washed out with freshwater. Pay particular attention to removal of any visible fouling. Please note that marine pest larvae, which are invisible to the naked eye, can be transported alive in seawater.

What's in it for you?
- Extend the life of your boat and gear
- Reduce vessel running costs (lower fuel consumption)
- Reduce maintenance costs
- Protect our coastal waters from marine pests for future generations



Marine pests

The following species are currently causing havoc in our marine ecosystems.  If you notice marine pests occurring in new locations, please contact:
DPIPWE Marine Pest Hotline:  0408 380 377 / www.dpipwe.tas.gov.au

NORTHERN PACIFIC SEASTAR (Asterias amurensis)
Threat:  Highly invasive voracious feeder of wild and farmed shellfish and a variety of other marine animals. It has few predators.
Transfers:  Hulls of boats, fishing gear, ballast water, natural spread.
Northern Pacific seastar
NEW ZEALAND SCREWSHELL (Maoricolpus roseus)
Threat:  Can rapidly spread and compete for food and space with native screwshells and scallops on sandy seafloors. It has few predators.
Transfers:  Ballast waters, natural spread.

EUROPEAN GREEN CRAB (Carcinus maenas)
Threat:  Preys on scallops, mussels and oysters and other shellfish and crustaceans. Takes over habitat of native crabs and causes havoc amongst local fisheries and oyster farms.
Transfers:  Aboard boats and on fishing gear.

EUROPEAN CLAM (Varicorbula gibba)
Threat:  Spreads rapidly and can completely alter the seafloor ecology. Competes with native species.
Transfers:  Aboard boats and on fishing gear.

LONG-SPINED SEA URCHIN (Centrostephanus rodgersii)
Threat: Completely modifies habitats by heavily grazing on kelp beds, totally denuding them.  Kelp is essential food and shelter for many marine animals.
Transfers:  As the ocean’s temperature increases, this species is extending further south from its native east Australian mainland warmer waters.
WAKAME / JAPANESE KELP (Undaria pinnatifida)
Threat:  Highly invasive, grows rapidly and has the potential to exclude native seaweeds.
Transfers:  Its spores are easily transported aboard boats, on fishing and dive gear, and in natural currents.

Coastal weed

SEA SPURGE (Euphorbia paralias)
Threat:  Changes the shape of beaches and dunes, which increases erosion. Covers sandy beaches, restricting nesting sites for beach-nesting shorebirds
Transfers:  Seeds transported in ocean currents
