Innovative trial could be game-changer in restoring Australia’s shellfish populations

 

By OzFish Unlimited

A new product being trialled in South-East Queensland could be a game-changer for shellfish restoration in Australia.

A mesh bag made from biopolymers from 100 per cent vegetation that has been sustainably sourced is being tested to see if they can grow oyster clusters in the Maroochy River and Moreton Bay.

OzFish Unlimited,  Australia’s fishing conservation charity, has teamed up with Healthy Land and Water through the National Landcare Program and the Bunya Bunya Country Aboriginal Corporation to test out the pilot project.

OzFish is using the trial to see if the mesh bags (known as BESE bags) could become a lightweight alternative to the Robust Oyster Baskets (ROBs), which are used to restore shellfish populations but are much heavier, expensive and more time consuming to construct.

“The biggest issue is not just getting the shell in the water.  We want to create a 3-D structure to allow more organisms to grow on the shell such as baby oysters and also to provide habitat for fish,” said Abbie Taylor, OzFish Project Manager – South-East Queensland.

“By creating a structure that’s got that height and complexity, you’re creating multiple areas for new oysters to recruit and creating additional habitat for crabs, worms, snails and all those other critters to hide in.

“One of the benefits of this bag is they slot into each other. They’re like sandbags – they’ll cement in with each other.”

OzFish volunteers and members of the Bunya Bunya Country Aboriginal Corporation placed 90 bags each at oyster leases in Moreton Bay and Bli Blion the Maroochy River as part of the trial.

“They come in 100-metre lengths and you can cut them to size. They’re super easy to fill. It’s like a sausage skin, you have a big roll and tie off one end with a knot or a C clip and you put it in a bucket, fill it with shell and then tie off the other end,” Taylor added.

Dr Ben Gilby, a Senior Lecturer in Animal Ecology at the University of the Sunshine Coast, has been working with OzFish for several years and he is confident this project will deliver on multiple fronts, including water quality.

“One adult oyster filters one bathtub of water per day. They take in a lot of nitrogen and a lot of pollutants out of the water column, which is one of the most important things they do,” he said.

“They’re even doing things like taking sediment out of the water when floods come through and literally deposit it underneath them and store that for many years. They’re very efficient little creatures.”

The BESE bags have been placed in intertidal areas and it will not be known until the end of the year at the earliest whether the trial has been successful with one of the main concerns that the local wildlife will find the material too tasty to resist.  If the trial works, they could be deployed in coastal and inland areas throughout Australia.

Since European settlement in Australia in the late 1700s, shellfish have been nearly wiped out in many areas to critically endangered levels.

“The best estimates are that somewhere between 96-99% of oysters are gone from Moreton Bay,” Dr Gilby added. “We talk a lot about endangered ecosystems like corals and seagrass but there’s none worse than oysters.”

This project was funded by the Healthy Land and Water, the Australian Government’s National Landcare Program, OzFish Unlimited and BCF – Boating, Camping, Fishing.

From Near Death to Thriving:

 

By Sarah Waters

The Northern Rivers Koala Hospital in Lismore recently shared a heart-warming story about a very young koala joey, named Hobi, which came into its care.

Discovered cold and alone under a bush, Hobi was taken to the Northern Rivers Koala Hospital in February this year.

The hospital’s veterinary team were initially concerned about the young joey’s chances of survival.

He weighed a mere 700 grams upon arrival and was suffering shock from exposure.

Veterinary Clinical & Research Director at Friends of the Koala Dr Jodie Wakeman said Hobi could barely sit up, was very dehydrated, had an erratic heartbeat, abnormal head and eye movements and his body temperature was so low that a reading did not register on the thermometer.

“Hobi surprised us all – with some medications, fluids, intensive care in a humidicrib and lots of TLC, he slowly improved over the next few days,” Dr Wakeman said.

“It wasn’t long before Hobi was eating leaves and starting to move around,” she said.

Hobi defied the odds and in the week’s that followed he gradually became stronger and stronger.

His heart rate settled, his body temperature and hydration normalised, and his metabolic and neurological problems disappeared.

After two months in intensive home care with Joey Care Coordinator and part time vet nurse Liz McLeod, Hobi progressed to Koala Kindy and is now undergoing his rewilding journey.

At Koala Kindy, run by Friends of the Koala, Hobi will learn how to feed himself, climb and interact with other koalas, before eventually being released back to the wild.

Dr Wakeman said Hobi was the ‘little miracle koala for the year.’

“We are so pleased to see him thriving and so proud of our veterinary and volunteer teams that help to save koalas like him,” she said.

Joey koalas rely on the care of their mother from birth to about 18 months of age.

At the Koala kindy, trained volunteer koala carers will continue to give joeys supplement milk once or twice a day, administer medications, visually assess their health and weigh them regularly.

Northern Rivers Koala Hospital needs funding: Urgent appeal for support

 

By Sarah Waters

Koalas are becoming an increasingly rare sight in NSW and the one organisation that is dedicated solely to their care in the Northern Rivers is desperately trying to keep operating as normal.

The Northern Rivers Koala Hospital, operated by Friends of the Koala, has made an urgent plea for financial support.

A decline in donations and available funding has threatened the hospital’s ability to operate effectively.

The hospital is specifically designed for the medical treatment of koalas and is the only wildlife hospital in NSW licensed to vaccinate all treated koalas against Chlamydia – the number one cause of death for koalas in the Northern Rivers.

General manager of Friends of the Koala Silva Everaers said more than 350 Koalas are treated at the hospital each year.

“From July last year we’ve seen a 20 per cent increase in koalas coming in, versus the year before,” Ms Everaers said.

“It will continue to increase as the threats to koalas are increasing with climate change, natural disasters, habitat being destroyed causing more koalas on the road, which leads to car hits, dog attacks and more diseases due to stress.

“So that’s obviously concerning, and it has been really, really busy for our volunteers rescuing and caring for them,” she said.

The Northern Rivers Koala Hospital was formed in 2019 and is part of the wider Friends of the Koala (FOK) organisation.

The FOK organisation receives government grants for certain projects including a recent grant to vaccinate 300 koalas against chlamydia.

But no government money is received for the operational cost of the koala hospital.

Half a million dollars needs to be raised by Friends of the Koala each year to cover the hospital’s annual operating expenses.

It is set up with diagnostic and treatment tools including ultrasounds, x-rays, a blood bank, as well as surgical and pathology equipment to provide specialised 24/7 veterinary care to koalas.

Until more funds become available the hospital may not be able to continue in its current capacity.

Ms Everaers said the priority was to keep the hospital funded and veterinary staff paid.

“That really is where the research and the magic happens,” she said.

“We work with over 300 volunteers, who do an absolutely incredible job rescuing and rehabilitating the koalas treated in our hospital, and because of that we are able to keep operational costs really, really low.

“But we can’t do it without financial support, in the end, there’s medicine, veterinary staff, the equipment we need, research facilities – it’s not free.”

Friends of the Koala have set up a special donation drive, appealing to the public’s generosity to help keep the hospital in operation and maintain their high standards of care.

Anyone with a heart for wildlife, including business owners and philanthropists, can become a ‘Friend of the Northern Rivers Koala Hospital’ at: friendsofthekoala.org or support by donating to the organisation.

Friends of the Koala are a grassroots organisation with more than 35 years of experience working on critical, on-the-ground activities to conserve habitat and protect koalas individually and as a species.

It originated as a charity focused on planting trees but has evolved into a multifaceted organisation that also provides 24/7 koala rescue, medical treatment, research, advocacy and community education.

Friends of the Koala has successfully rehabilitated and released over 2000 koalas back into the wild since its inception.

The Northern Rivers is home to one of the last significant, genetically diverse koala populations.

NSW Government supports Northern Rivers green bin education

NSW Government supports Northern Rivers green bin education

 

North East Waste has received an $89,700 grant from the NSW Government to help educate Northern Rivers residents about what types of waste can and can’t go into FOGO (Food Organics Garden Organics) bins. The funding aims to ensure that food waste and garden waste such as plants stays out of landfill. It also aims to keep green bins free from contaminants like plastic.

Earlier this year, North East Waste and its member councils (Ballina, Byron, Clarence Valley, Lismore, Kyogle, Richmond Valley and Tweed) announced that Food Organics and Garden Organics (FOGO) bins should now only be used for food scraps and garden waste. This means that materials like paper, cardboard and teabags do not go into green bins as they can contaminate the final compost made from the organic content.

North East Waste Education Coordinator Linda Tohver said the assistance from the NSW Government would help councils to continue promote the right message and increasing awareness in the community.

“The response from community has been positive so far, and we need to keep spreading the word,” Ms Tohver said.

“The messages are simple to follow and will help keep potentially harmful items out of our green bins so that we can create the best quality commercial compost from residents’ food scraps and garden waste.”

What CAN go in your green bin What CAN NOT go in your green bin
Fruit and vegetable scraps Fibre-based products (bamboo, cardboard, paper etc)
Meat and bones Paper towels, serviettes, tissues, napkins
Seafood and shells Compostable or biodegradable products (excluding AS 4736-2006 kitchen caddy liners )
Pasta, bread, rice and cereal Vacuum cleaner dust
Eggs and dairy products like cheese Washing machine and dryer lint
Loose tea leaves and coffee grinds Pet poo and poo bags
Garden waste (leaves, clippings, weeds etc) Tea and coffee bags
Council approved compostable kitchen caddy liners that comply with AS 4736-2006 and the paper used to wrap food scraps. Treated wood and timber
  Plastic
