NOVELTY - Worm harvesting system comprises (a) vermiculture unit comprising (i) structural elements that define a hollow interior fillable with an introducible organic substance, (ii) perforated surface for supporting the organic substance, and (iii) solid and fixed walls of the structural elements extending upwardly from the perforated surface to a void area located below an uppermost edge of the structural elements, and (b) an extractor insertable into the interior via the void area.    USE - The system is useful for harvesting worm (claimed).    ADVANTAGE - The system saves time and labor.    DETAILED DESCRIPTION - Worm harvesting system comprises (a) vermiculture unit comprising (i) structural elements that define a hollow interior fillable with an introducible organic substance and through which worms for converting the organic substance to environmentally compatible products are able to migrate, (ii) perforated surface for supporting the organic substance, and (iii) solid and fixed walls of the structural elements extending upwardly from the perforated surface to a void area located below an uppermost edge of the structural elements, removal of worms from a region of the interior that is below the void area being prevented by the solid and fixed walls, and (b) an extractor insertable into the interior via the void area, for extracting, from the hollow interior, solidified organic substance to which the worms have upwardly migrated, allowing grown worms to be separated from the extracted organic substance and collected. An INDEPENDENT CLAIM is included for vermicomposting apparatus, which comprises (a) structural elements that define a hollow interior fillable with an introducible organic substance and through which worms for converting the organic substance to environmentally compatible products are able to migrate, (b) perforated surface for supporting the organic substance, and (c) an inclined surface for receiving worm processed byproducts downwardly discharged through the perforated surface.
