The Tasmanian government is developing new research to investigate how Tasmanian and northern crayfishes are different, and that could lead to a more effective response to the threat of invasive species.
The new study, which is expected to be published in the journal Marine Ecology Progress Series, has also been launched to give a better understanding of how different species of cray-fish are being affected by climate change.
“The idea is to have a clearer understanding of what’s happening to the marine food webs in Tasmania, because we have this big problem with invasive species in our region,” Tasmanian Minister for Fisheries David Heffernan said.
“It’s going to be quite interesting to see what we discover.” “
New research into Tasmanian, northern and western crayFisherman John Devereux says the idea of combining the different species together is a good one.””

“There is a lot of complexity in the digestive system of all the different craycrows in Tasmania,” he said.
Tasmanians are looking for solutions to the issue of invasive predators. “
But what we’re doing is trying to look at how the different organisms are different.”

Mr Devereaux said research showed the presence of an invasive predator such as a white-tailed deer could cause a change in the fish’s digestive system.
“It changes their whole diet and that’s not the best thing,” he explained.
“What we’re trying to do is look at different things, to see if there’s a more efficient way to control that than just just to put a fence around it and not put a predator into it.”
The idea of using a single, large fish to control an invasive species has been discussed before.
The Government announced last month it was working on a plan to reintroduce the northern crayshaft cray to Tasmania.
But it has been months since the plan was announced.
TAS Government said the plan would not be ready for commercial release until after next year.
It has also said the northern and southern cray were still too complex for commercial capture.
