Someone in my school did a project on this for his aquaculture master degree, not with the shrimps we keep but for food shrimps. The conclusion was that 11.5hrs/day got the best growth rate (breeding wasn't part of the experiment since the breeding shrimps are mostly wild caught for those food shrimps). I tried but couldn't find the link anymore and gave up, so believe it or not and take it with what it's worth. I try to do 8 to 11 hrs myself.
