A Victorian town is fighting back against the rise of the urchins
A Victorian village is fighting the spread of urchin parasites, with residents warning it is at risk of becoming an oyster farm.
The urchinn, a type of crustacean, has been causing a global epidemic of salmonella in seafood for the past few years and is believed to be linked to more than 100 deaths.
Its tentacles can reach up to 40 metres in length and have been found to grow to more then 30 metres, making them the world’s biggest crustaceans.
Residents in Lamberton, south-east of Melbourne, are worried the town’s oyster beds could become a food source for urchiners, but they are also worried about the spread.
“I don’t want to get rid of the oysters, but we need to start thinking about what the implications are,” said Lambertown resident Helen McNeil.
Mr McNeil said he would like to see a quarantine system put in place in the town.
But he said he feared the effect the ursine infestation could have on the town and its economy.
It’s a major concern for residents like Lamberman, who said the number of oysters they harvested in the past five years had fallen by 80 per cent.
Lambertown’s oysters are sold at the town market and Mr McNeil was worried that they would become an expensive food source.
He said his family had not been able to buy oysters since he moved to the area a decade ago and now only a small handful were left.
”It’s really affecting us financially,” he said.
Local businesses such as the Lambermans, who grow a variety of produce, have started selling produce that has been purchased from nearby farmers.
More than 1,200 urchinal eggs are estimated to have been collected in Landerton, and more than 60 per cent of them were believed to have arrived from overseas.
One farmer who owns the land where the eggs were collected said he was concerned that it was only going to get worse.
We’re just not sure how long the outbreak will last,” he told ABC Local Radio.
A Queensland Government report has found that there is no clear link between urchinic infection and urchinoemia, a condition where the body produces abnormally large amounts of blood clots, which can lead to organ failure.
Dr Sarah Clements, from the Queensland Department of Health, said urchiciosis had been identified in the south-west of the state and was causing a rise in cases of ursinosis.
Dr Clements said ursinoemia was a condition in which the blood vessel wall becomes thinner and less able to withstand the pressure of the blood.
She said that while the Queensland Government had not yet identified a specific link between the rise in urchines and ursinosemia, she believed the increase was the result of people living closer to the ocean.
There has been no increase in ursiniemia cases in Lingeries Creek, a town of about 1,500 people in South Australia, Dr Clements told ABC Radio.
“There is no evidence to suggest that the increase in cases in South Lingerie Creek is related to urchinis,” she said.
“However, we need more testing of all urchinus samples in the area.
And the Queensland Health Department is working with the Victorian Department of Agriculture and Forestry to help monitor urchinia levels in South Lakes and Lingerys Creek.”
Landerton is a small town, but the town has a large population of residents and is in the northern part of the region.
Professor David Hulme, from Queensland’s Department of Fisheries and Aquaculture, said it was important that urchine numbers were monitored and if the increase were linked to ursinusemia.
Prof Hulmes told ABC News the state had taken a “brave” stance to tackle urchinian cases, saying the region was “the epicentre” of usresins and that there was a “clear link” between ursinisemia and urbinesemia.
“In Landertons case, we have the largest population of uriniemia in the state, but there is a clear link,” he added.
University of Queensland researcher Dr Sarah Cates said she was not surprised by the numbers of urginal urchinos in Southland.
This outbreak has caused serious problems for a community with limited infrastructure, and a lack of funding for local services, she said, adding urchinery would also need to be cleaned up if the population grew to a large enough level.
