Species used in vermiculture
Annelid worms are currently about 20,000 species, many of which are susceptible to cultivation. Among the sea earthworms, we must mention the Nereids, worms used as fishing bait and even for human consumption.

Earthworms arouse more interest due to their importance as soil stabilizers and biofertilizer production. Of the more than 4,000 species of worms that live in freshwaters and ground, about fifty are cultivated or are in the process of being investigated to be transferred to private companies. The best known family for these matters is that of the Lumbricids, although other nearby groups also bring significant environmental benefits.

Obviously, commercial species meet the requirements of all biological separation for mass rearing:
Short life cycle.
High reproductive tax.
High environmental tolerance.
High adaptability to overcrowding.
High disease resistance.
