Possible use of earthworm Eisenia fetida (Sav.) biomass for breeding aquarium fish

The aim of this research was to find further arguments advocating the idea of vermicomposting in household and school conditions. An alternative use of Eisenia fetida biomass was feeding it to aquarium fish (Poecilia reticulata). Fish were bred in two groups, each with six specimens of both genders. The control group consisted fish fed on standard food whilst the treatment group was fed on earthworm biomass. Compared to those fed on a standard food, earthworm-fed fish increased brood number significantly and produced twice the offspring (P < 0.001).
