"Experimental work on the mass culture of invertebrates
for production purposes began in Russia at the end of
the nineteenth century (Ivleva 1973). White or pot worm
cultivation was developed in the 1940s as a result of
expanding fish culture programs in the former USSR. Studies
on the biology, nutrition and cultivation of white worms are
reported in Russian-language publications but few have been
translated into English (Vedrasco et al. 2002). Published
reviews describe rooms of wall-to-wall racks stacked with
wooden boxes (50 x 40 x 12 cm) of worms (100 - 300 g/box).
Many fish breeding facilities maintained over 1,000 of these
boxes and produced 500 kg to several tons of white worms
per season to feed 2.5 to 3 million juvenile sturgeon (Ivelva
1973 et al. 2004)." (Marsh 2014)
