Hi Gang,
Just to chime in, well, yeah. The ability of any captive breeding program to unhinge a wild-caught market largely depends on the ratio of demand to complexity of rearing. Several have tried to make a business of breeding, rearing and selling cephalopods (Cephsource, OctoPets, LongArmLabs) with no real success. I don't know how LLL is doing, but if anybody can do it, it's Chris.
There's also not a lot of money in raising cephalopods. Yeah, WE think they're neat, but the real aquaculture research money is going to come from the food market. If we could show Asia that cephs could be massively cultured, then the science and technique refinement would really take off.
Until then, it's us fanatics tearing our hair out and coping with Joe Six-Pack budgets.
If you want a bimac, patience is your best friend. After keeping dozens of them over the years, I noted a pattern: bimacs start showing up in pet shops and iShops around late summer through about February - and they seem to die off between March and June.
My guess is that eggs are laid in the late Spring/early Summer, and the new generation of bimacs are too small to be found by collection divers until close to fall, when they're about the size of a lime.
This is merely an anecdotal observation and hasn't been tested. If anyone has done a formal study, I'd love to hear about it.
On a side note, my wife and I are rearing not one but TWO clutches of small eggs of an unidentified species from indonesia. The first clutch is due to hatch any second now- the embryos flipped inside the eggs last week and as of this morning there were no yolks left. They're in an experimental rotary current plankton breeder. It'll be interesting to see if we can get them to the benthic stage, let alone grow them out completely.
Good luck with your eggs! CephJedi
