Worm breeding is an activity involving mainly the raising of worms which are later used for other purposes. By tradition, the commercial aspect of worms has been associated with fishing. However, this is perhaps one of its least important applications.

This flour is used in the preparation of food for human use as a protein complement in the making of hamburgers, minced meat and sausages. It is also employed in the manufacture of balanced animal food products.

The alive worm is also used as food for frogs and fishes in aquariums or hatcheries, as well as bait in the fishing industry.

The collagen present in the worms is used in the pharmaceutical industry, and antibiotics have been obtained from the ceolomic liquid. Medicine experts are also studying this annelid because of its immune and tissue regenerative capacity.

Another aspect of worms is related to the production of humus, which is intimately and inseparably connected to waste recycling: they eat waste and excrete humus.
It turns a serious problem into one of the richest organic fertilizers.
