Hey Gresham, I was planning to call Randy on Monday but since you popped up... My rot culture has been going strong since December ( Reeds starter). Now it has fizzled and I have heard from others that 6-9 months is about normal. My thinking is that you are basically inbreeding for 1000's of generations and without new genetic material you evenyually run into trouble. Is that the case or am I way off? In any event I'm going to order more on Monday, my question is... Should I start completely over or disperse the new rots into my (5) culture tanks to gain the "new blood" advantage?

I don't know David, I think I've had my main L-Strain cultures going for about a year now...had some crashes early on but it seems now they're going pretty solid (of course, now that I've said this I realize I've just jinxed myself).
I wonder if the small particle size on the OSI Aritificial Rots could be helpful with SMALLER fry (i.e. gobies) for people who don't have access to S / SS-Strains...
HMM.

sorry about your cultures, and while I am weary of cultivating my own... it will be just a matter if time before I expand... I use to breed different types of african cichlids but that was fairly easy and I quickly ran out of space. Most likely wont be a serious breeder anytime soon, I only have one clown at the moment and I doubt if she will reproduce through fission. The good news is that the new pair should be coming in on tuesday.

Rotifers beginning to recover, all cultures are nearly clear this morning and I had them emerald green last night. The even more exciting news is that I have to believe the frozen rots saved my butt, the gsm's are going strong on this the third day, modest losses and I had very few live rots in there, mostly frozen. My hope was that having at least some live would intiate feeding and they'd end up taking som dead in the process. No way to doccument this but I think it worked
So... maybe while dead foods may never be a viable option on their own they may have some value as supplemental feed when cultures are down. Remember these were newborn larvae that I believe must have eaten the frozen rotifers, that is a good sign. They all had bright silver bellies an hour after I added the food.
I have another gsm nest going off in a day or two, I don't need them and wasn't even planning to pull the nest. Now I am thinking of hatching it and feeding only one initial innoculation of live followed by frozen exclusively just to see what kind of survival rate I get (if any)
I can tell you our IRC systems have been going strong for several years now. We never have crashes, but we do have a decline in density, when some one forgets to refill the feed doser, or Chloramx.
As far as the inbreeding goes, I don't know of any culture around that isn't inbreed. This is not my expertise though, I'd have to defer this Q to others in our company.

Hi Kathy and all,
About the enzyme hypothesis do you have any paper testing this ? I´ve digged a little and found one saying the opposite
"Ontogeny of pancreatic enzymes in larval red drum Sciaenops ocellatus" Aquaculture Nutrition 2000 6;183-192
Not to go against it, just trying to bring us food for thought.

David- Glad to hear about your good news!
I am getting my clown pair tomorrow =D and will post any results about my success rates for rearing black ocellaris (Tank Bred). Still, my clowns could take months to produce a nest but I will keep a log. If anything the serious breeders can sake their finger at me for making to many mistakes... ha
aomont, thanks for the article, I will see if the Clemson library has access to it the next time I am there. I would assume that we do since we have a fisheries major. thanks for all the info

David, so how was the survival rate with exclusive use of the frozen?

GSM survival rates are brutal at the best of times, after spawning regularily for over three years, I've only managed to get three really, really good sized batches past meta. I lost one to the heat wave May '05 (along with just about everything else) another to oxygen starvation/drowning after forgetting to turn the air back on after siphoning and the last one is 15 months old and just getting to market now. Anything smaller than really, really good survival ends up being brutalized by internal (infernal??) in-fighting. OK, too much info and I don't want to deter you, the opposite is true as I'm at wits end looking for the "magic bullet" if you will regarding survivability. Just keep us posted for sure, good or bad.

in the Naturose thread. Maybe this is worth a shot for your experiments..lots of increasing sizes...hear's the link...hope this helps, will be interested in any results. Carl

you guys are killing me ! lol
i just placed another order for the naturose, now i ll have to get the gps also lol
his challenge in raising larvae is very fascinating to me as a scientist. hopefully i ll have some success. ive acquired i believe ever food source attempted for larvae. now i just have to hope my pair spawns again!
