FIELD: vermiculite cultivation, in particular, selection of optimal conditions for cultivation of annelids.
SUBSTANCE: method involves placing annelids into container filled with different substrates; holding; opening container; determining preferendum by frequency of encountered annelids and amount of laid cocoons; charging annelids from the top into container; arranging substrates in layers and dividing said layers by means of netted partitions; holding annelids during 1-2 days at temperature of 18-22 C.
EFFECT: simplified method for determining of optimal substrate composition for cultivation of annelids, increased number of substrates tested for one cycle and reduced time consumed for experiment.
