They say it's probably normal...but One thing that has always disturbed me is ballast water...I wonder if these are a WA item or not...good if they are..not so good if they are not! You would think after all these years the guys crayfishing would have said..ohhh look what I have caught.

Covered in coarse hair and sporting a pair of crab-like pincers, the first known live specimen of a red reef lobster was caught off the WA coast last week.

Thousands of kilometres from its normal breeding grounds of South Africa, Madagascar, Hawaii and Java the creature was pulled in a rock lobster pot at the Abrolhos Islands about ten days ago and caused a flurry of excitement in WA fishing circles.

For 29-year-old Dongara fishermen Clay Bass it was just another day fishing when he pulled what he described as a cross between a lobster, prawn and scampi in his pot.

"It was about 5.30am and we pulled a pot which had an unusual small lobster in it, at first I thought it was a scampi so I brought it back to a friend's place in Port Denison, who recently studied biology in Queensland and who passed it on to the Department of Fisheries," he said.

"The interesting to part of it was no other sample has been caught in WA before so this is the first live specimen caught in WA."

Mr Clay said the hairy lobster was 12-15cm in length - which is their full length - and unlike WA lobsters it has claws like a crab.

Department of Fisheries senior research scientist for rock lobster Simon de Lestang said the lobster has been identified as a male and could come from a naturally occurring habitat in WA.

"I think they live there, I don't think it's come from anywhere else, they are commonly found in Hawaii because people look for them, but I would say there is a naturally occurring population in our waters," he said.

"It is relatively elusive and that is why we haven't seen it before and because it is nocturnal that reduces its chances of being seen."
The lobster which has not yet been named will be put on display in the Marine Discovery Centre at Hillary's Boat Harbour.


From my window in Hobart, I look out over the Derwent River. It's a fantastic view across the slate-grey sea. But below the tranquil surface of the Derwent, there is a battle raging between the locals and some aggressive new arrivals - northern Pacific seastars. The first of these seastars probably arrived as stowaways on ships from Japan about 20 years ago. They thrived in the cool Tasmanian waters and bred so furiously that there are now almost 30 million of them in the estuary.

Community divers pulled 30,000 sea stars from the Derwent River in 1993 and hardly put a dent in the population

It is quite possible but unlikely that they are an introduced species. Many people do not appreciate the wide variety of crayfish, both marine and fresh water. Australia has the widest variety of freshwater crays, from memory over one hundred, some of which live in very small specific environments. It would be no surprise to find a new species off shore.

The risks of larger species invading a coast line are small but have a look what can happen: en.wikipedia.org/wiki/Lamprey

Like the oil spill in the Carribbean, it is only a question of when and where. In Newcastle we have an a verage of 40 ships per day waiting to be loaded. They all dump their ballast and they come from everywhere.

Wish some bloke would introduce green lip mussels up this way!

I wish there was strong legislation in place that required water ballasted ships to change their ballast water multiple times while en route to our waters.

That is one kind of immigration no sane person wants.

Ballast water carrying exotic marine life has totally buggered the fishery in Port Phillip Bay.
