ABC Science: Ann JonesBut the reintroduction failed to take, and in the meantime, disaster struck some of the reserve dams where the fish were being kept, according Nick Whiterod, who has been involved with the rescue attempt.
"The water level [in the dams], just one summer I got a call from the land owner and he said 'it's plummeted'. So it dropped probably 4 metres down to a metre," Dr Whiterod said.That was about three years ago. Dr Whiterod said they hadn't got any fish back from there since.They were able to salvage some of the Yarra pygmy perch in the dams and they have been trying to breed numbers up again in captivity, but Dr Whiterod describes the situation as"precarious".
The long-term hope is to be able to attempt another reintroduction of the fish into the Murray-Darling. But in the time that they've been keeping the breeding stock alive, inbreeding has significantly reduced the genetic diversity of those remaining fish. This, together with small numbers of fish, and the previous failure of the reintroduced fish to survive, mean hope is fading, according to Dr Wedderburn."We'll probably have another year or so at the most to get these fish that are in captivity bred up to reintroduce into the wild."
I’m honestly surprised that this would be the first. Timeliness of this article is also interesting
I know that I will remember this at the ballot box, but I doubt that many other people will even know that it's an issue.
Pure disgust at those who have enabled this..
