The worms are fed in accordance with a continuously growing nutritional chain (28, 29) in a manner such that a migration of a work population following said chain is produced. At least once an accretion (5) of the worm population is separated therefrom, leaving a migrating stock population (6) in the nutritional chain (28, 29), whereas the accretion (5) migrates in the direction of an accretion nutritional chain which starts from the stock nutritional chain, and can be harvested therefrom. Means, e.g., inhibiting means (20), anti-creep means, supplying means, and heat-exchanging means, are described for raising the worm under conditions which are optimal for the farmer and depend, for instance, on economical and on season conditions. …<??>The method and/or device can be advantageously used for producing work casting, since the worms can be maintained under conditions, whereby the nutrition conversion velocity of the nutrition offered to the worms is maximal over a long period of time. |
