Breeding Procambarus clarkii
- Hi, I am a new member. My son and I recently raised a batch of babies
after buying a female in berry. We now have a dedicated crayfish tank
and would like to try breeding the female again and raising some
more. We have the female and a newly acquired male in a 58 gal tank
with lots of rocks, caves, artificial plants, and a couple of logs.
Are there any tips on getting these guys to breed? Thanks!
- Keep the water at a warm level. When it gets cooler they slow down and they
would rather eat each other than mate. Your in for a real spectacle if
you're lucky enough to see the courtship and mating. It's a quick strike by
the male, put one claw around her two claws, the other around her torso and
15 minutes of bliss. Then its off and let's pretend it never happened.
Several weeks later you will have your berried female, if the male did his
best. Good Luck.
- After mating, how long should it take for the female of this species to
produce eggs? Is it simply a matter of time or does there have to be
certain environmental conditions before she will produce?
- Usually it takes around 6 weeks but it depends on the species, and
environmental conditions. Again warmer is faster.
Find a piece of 1" to 2" PVC pipe and cut a piece about 4" long. I spray
paint mine black because they end up that way anyway (algae). I also cut some
cross cuts in the top so I can see if a crawdad is occupying the pipe. You
may want a few so she can choose.
When she is gravid or berried the PVC also gives the fry a place to hide, as
you must have seen with your first batch they come and go from her pleopods
or flappers until they eventually can stand on their own. I generally don't
move them until they are about one and a half inches in size.
You can go to Walmart and but some flake food or granule type food for the
fry. If you see the food isn't being eaten its too much.
If you put some plastic plants in the tank you will see true territorialism
at its best.
The largest on the top and on down. When they get about an inch get some
plecostamus type food (disks of algae) from Wally world and drop them in the
tank. You will see a tiny crawdad eating the disk like it was a big round of
cheese, continually turning it as if they were a buzz saw. Good luck. Jake
