New Euastacus ?



From Geoff Edney 

I caught three of these crays using hoop nets and liver. They were living in a stream with narrow riffles and shallow pools with some deep holes. It was about 500m (above sea level) and the vegetation was becoming alpine. There was dense undergrowth and many over hanging wattles and eucalypts. These are adult crays and I could only guess at the age. Alpine species tend to grow slowly so they could be ten years old or two.




In the same section of stream are Euastacus armatus , in fact I caught an E. armatus in the same net at the same time as one of the new species (this is unusual form my experience). It was late autumn before the major bushfires! I have been back to the site about a year after the fires and it was completely burnt out. All the vegetation had been burnt, however, there was regeneration in the Eucalypts and some understory plants were sprouting. There was a huge sediment load in the creek and no sign of any crayfish although I only had a day there. I look forward to shearching for these crays again and hope a few more years of recovery will see the habitat and the cray recover.
