There is an article by Gbewonyo et al., (1994) on large scale cultivation
of C. elegans which may be of use to you: Bio/Technology 12:51-54.  You
could also try using baffled flasks to increase aeration of liquid
cultures, and hopefully, the worm yield.  I use grinding in a liquid
nitrogen-cooled mortar and pestle (1.5-2 ml buffer per gram worm pellet)
to get lysates which yield cytosols of around 8 mg/ml protein.
