Adrian,
I just had a quick look through the last couple of years. About 35
papers on cryopreserving sperm and embryos in everything from barramundi to
sturgeon. Not much interest in eggs as such it seems. From stuff I've looked
at in the day job, there's no reason you couldn't, given the equipment
(liquid nitrogen, tanks, etc) but working out the correct freezing regimes
and protecting solutions would be a big job.
To everyone,
MYSTERY FISH
Effie and I were getting our little group of lacustris out for a
holiday in an outside pond, when we realised we had a ringin. We have
lacustris from 2 sources, an older group and a newer group bought quite
small at ANGFA Canberra 95 conference, and I think that's where this fish is
from.
It is about 50mm long, looks to be male. Base colour of the body is a
uniform warm gold. Inner halves of the fins and tail are same gold colour,
outer halves are clear. No black on fins or tail. There is a reasonably
pronounced black body stripe with fine red lines immediately above and below
the black. There's a faint red earspot, and fine black lines on the lips.
The eyes are normal rainbow size rather than the big eyes on the lacustris.
Pretty fish, altogether. Any ideas? If we can't sort him out we'll just keep
him as a display animal with our other lost soul (a probable inadvertant
cross from a display tank). Fortunately we found him in time and have no
suspect progeny.
Thanks
Chris Howe
