I have a couple here and one of them has eggs. I'm trying to find out what colour the eggs are when fertile as different species seem to have different coloured eggs.
I have googled and yahoo'd all afternoon to no avail  :(

This is an older picture of the one with the eggs...

Penny,

The crayfish in the picture you posted is not a western australian marron, but a female cherax quadricarinatus, or "Redclaw" cray.
You can tell by the very pointed shape of the rostrum (point on the end of its head), the rather deep and pronounced post orbital ridges (ridges on its head either side of the rostrum) and the distinct red blotches on its abdominal segments (tail section). And you can tell its a female because of the rather narrow profile of its propodus (hand/claw) in comparison to the width of a male c.quadricarinatus' propodus, also the lack of the bright red soft uncalcified membrane on the outside margin of the claws usually tends to mean a female specimen.

The picture that wayne posted is indeed a cherax tenuimanus or "western australian marron". You can tell by the shortened and curved rostral spine in comparison to the redclaw and the irregular calcified and slightly raised spots on its carapace (middle section) and abdomen.

Hope this helps!

Thanks everyone.
The egg she was carrying are orange anyway, so infertile.

lol about the eating, though I'm not sure if I'd eat anything that has spent it's life in a fishtank and chemicals  :lol:

They're pretty good these ones because you don't have to worry about them harrassing the fish and they add a bit of nice colour. Not to mention the interest for little kids watching them come out and eat their pellets.

Just an update on this.....

When moving house the weekend before last the kids noticed the yellow eggs had black dots (yes these were eye's).
As of Saturday they have started to release from their mother, she still has many yet to release.
Now the next problem is what to do with them all  :roll: .

aaron,
Both male and female are identical, though the male is alot younger and only half the size.

Even though they may both look the same, the cray in the pic you posted is deffinately a female redclaw crayfish. Depending on how small your male cray is, he may not have developed his soft red membrane on his claws yet. Alternatively you may have a male of a different species and the babies will be cross breeds.

Post a pic of your male cray and i'll tell you exactly what species it is.  :wink:
