Awesome thanks. Will start to gear up the lab to run the scale when it arrives. Might seem like an anti climax to age a fish that we already know the age of, but this small piece of information will allow us to confidently all wild caught lungfish for this monumental research project.
Some new developments on our AUL research in Australia. We wanted to better understand the population genetics and as with most things dealing with AUL's they didn't make our job easy. Using standard genetic analysis that works for 99% of all other fish, did not work as clearly for AUL's. So our next step is to throw everything at them including the kitchen sink and use a new technique called next Gen (SNP) sequencing which will open up much more of the genome to understand how the different populations stand genetically.

We have a meeting this coming week bringing together 10 researchers working on a large research effort to know how vulnerable AUL's are to extinction. Will provide more feedback on ageing wild fish soon, as well as some work to understand their diet In the wild and how often they seem to breed in the wild.

A bit of exiting news for AUL fans. They have a small piece of the centre stage on a new production from ICON films who produce River Monsters. Jeremy from River Monsters has a new 2hr show tracing the linkages of living ancient fish back to the rhizodont. Here's a link to the clip on Australian lungfish that I was lucky enough to help the film crew catch a few and film this piece.

Unfortunately we have to wait for a release date but it appears in the USA this weekend I think.

Thanks again Egon, the scales arrived safely. Now off to the lab to check we get the same age from the atomic bomb radiocarbon measurements.I sent the scales, hopefully they get through customs
Egon, wow how time flies. We processed your scales and unfortunately, the results were great. What we are finding with captive-raised fish is that the artificial feeds many people use typically contain old marine carbon sources which affect the radiocarbon dating method. We are writing up the results of the research now so given a few months for the publication process to proceed i will post it up. Thanks so much for helping us out. I'll send you some photos of what your scale went through in the lab.
