Exotic fish are dominating native fish in the Ross River.

While it may seem kinder to free or flush ‘Willy’ into the river or toilet, one Willy can become thousands of pest fish.

It’s suspected that Townsville’s itinerant population is dumping aquarium fish.

The Ross River has the highest number of exotic or introduced fish in Queensland.

Willy may be a Swordtail, Guppy, Platy, or Sailfin Molly.

They are aggressive to native fish, eating their food, chasing them out of their habitat and stealing breeding sites.

Willy’s partner Wilhelmina can produce a larger number of young than her native competitor.

They can live in poor quality water allowing them to survive where our native fish can’t.

Diana O’Donnell from NQ Dry Tropics said for new residents it seems exotic to set up a tropical fish aquarium at home but releasing the introduced fish when moving on, leaves a terrible legacy for the environment.

“When moving arrange for friends to take your aquarium or return the fish to a commercial aquarium but please do not release them.” Diana said.

Aquarium enthusiasts can keep fish indigenous to the tropics of north Queensland, instead of from foreign waters.

Diana said, “The native archer fish, purple spot gudgeon and empire gudgeon, while not as flashy as gold fish, do look very attractive in an aquarium.

Campers, beach-goers, and holiday makers are reminded to dispose of their rubbish appropriately over the Easter break. 

Mary-Alice Swan, Burnett Mary Regional Group’s (BMRG) new Coastal and Critical Aquatic Habitats Coordinator, said plastic, cigarette butts and other rubbish all have the potential to kill coastal and marine animals such as fish, shorebirds, turtles and dolphins. 

“When enjoying our unique beaches, rivers and beautiful bush over Easter, we should try to leave them in a better state than we found them,” Ms Swan said. 

“Put your rubbish back into your esky or bag; don’t leave it there to be washed into the waterways and the oceans.” 

“The recent floods and rains were a reminder of how litter and all sorts of things can be swept into creeks and rivers, even from urban areas, so it’s best to dispose of rubbish properly.” 

A UN study in 2006 revealed an average of 46,000 pieces of plastic in every square mile of the ocean. The health of coastal and aquatic habitats is of large concern to Ms Swan, whose responsibilities in her new role at BMRG include reducing threats to coastal systems.

Two new Reef Rescue publications will be available in March, helping to spread the word about the unique Queensland program. A fact sheet provides an overview of the program, the role of industry and regional NRM groups and how funding can be accessed by land managers across reef catchments. A new quarterly newsletter provides industry and regional groups with an avenue for sharing news about how their work is contributing to improving the water quality of the Great Barrier Reef lagoon. The first newsletter features stories about a new DVD produced by CANEGROWERS, managing for fire across Cape York and how Reef Rescue has given new graziers a hand in the NQ Dry Tropics region. Both publications, produced in partnership by Queensland Farmers Federation and Queensland Regional NRM Groups Collective are available online at www.rgc.org.au from 10 March 2010 or by contacting Lane Pilon on 07 4699 5000. The deadline for the next edition of the newsletter is Tuesday 30 April and contributions can be sent to sam@wombatcreative.com.au.
