settled larvae during transfer to grow out 

about 85 days after settlment i think

You are doing without a kriesel?  I find if my boggessi larvae settle on the bottom of the vessel they die.  Do yours not settle on the bottom of the 20 gallon tank you're using as a larval tank?

i am using a 20 gallon BRT . i guess i missed that while writing my journal on my smart phone .
to answer your question : i have not noticed loss associated with the larvae settling on the bottom unless there is a lot of detritus build up .
i have seen some kind of harpacticoid pod swarm boggessi larvae as they were resting on the bottom but it seemed like it was more of an annoyance to the larvae than anything. 
i have played around with a kriesel before but i didnt get better results than i can with the BRT.
last year i kept them alive for 3 weeks in 2 liter cylindrical containers while doing some experiments with different foods . i had the containers aerated at i bubble per second and about 70F room temp. 
after the trials i transfered the test subjects into the BRT. 
 
 

one thing i see to be important in raising these guys is to give the larvae enough space and dont let them clump up in a tight group . the larvae bumping into each other interferes with feeding and causes them to drop limbs . in my trials with the kriesel they were to concentrated and always bumping into each other causing alot of loss . 
part of it was me trying to dial the flow on my kriesel (i am not a kriesel pro) but after some adjustments i wasnt able to get them distributed as evenly as i wanted but it was a little better and i saw less loss . 
latley i have been working with larger volume tubs and i can spread them out evenly but now my hang up is stocking the large tubs with food.
keep me posted on your trials and ill do the same 
good luck  
 
 

Ok, thanks.  Hmmm...I'm not sure what I have been wrong.  I was working with them last fall quite a few batches using a fish bowl "kriesel" and could not get them past 12 dph I think it was.  I tried a couple batches fed a co-culture of NHBBS and L-type rotifers.  The longest living shrimp larvae were fed only NHBBS.  The population of BBS would always increase and age as the larvae never ate them all.  I was never able to figure out a good way to flush uneaten BBS out of the system.  I think I have figured this out now, and will try it on future batches.
 
I haven't collected a batch in a couple months at least (they weren't breeding in a high nitrate system they were in), but I did collect a batch on Dec 26th and just put them in one of my rotifer cultures (which actually happened to be in a BRT at the time), added some decapped brine eggs.  They didn't last 24 hours.  I was too busy to deal with them properly.
 
I talked with Andy Rhyne awhile back and got some ideas from him on flushing out uneaten BBS.  When I get this set up I will share in my breeding journal.  Hopefully working together we can get these guys nailed down. 

are you decapsulating your artemia before hatch? 

Yes, I do.  I set the Artemia hatcher in the same tank that I have the larvae tank set in where there is a heater that keeps both the Artemia and the larvae at about 81F.  Add a strong light to the Artemia and they will hatch in 6 hours if they are decapped.
