Growth rates at the four stocking densities for
E. andrei fed on fresh green waste (21, 15, 14 and
11 mg worm - ’ day - ‘) were broadly comparable to
published results for E. andrei and Eisenia fetida
(Savigny) fed on various types of waste. Neuhauser
et al. (1980) found that E. fetida gained weight at
rates which were dependent on population density
and food type. When fed 250 g of horse manure at
densities between 3 and 16 per dish, rates of growth
