Effect of different organic food sources on growth and production performances of earthworm (Perionyx excavatus)-a fish food

The project was developed with considering the importance and divers application of earthworm species in sustainable aquaculture and agriculture, and waste management. Among earthworm species identified taxonomically in Bangladesh, Perionyx excavatus was selected to be cultured in different organic food sources as this species is a suitably potential species for vermicomposting, and feeding roosters and fishes. The project was conducted in the vicinity of Khulna University for one year. The principal aim of the project was to evaluate the effect of four treatments namely, C, T1, T2, T3 containing varied composition of different organic materials[C: (soil: cow-dung = 5:95), T1 (soil: cow-dung: paddy straw: water hyacinth: kitchen waste = 5:50:5:30:10), T2 (5:40:10:20:25), and T3 (5:30:15:10:40)] on the growth and production performance of this earthworm. Five wild-harvest adult earthworms were stocked in each cemented ring tank, and let them reared with feeding of respective organic composites. The treatment T3 was found to be effective for production performance, and theT2 for supporting growth of this species. In addition to development of suitable food composite for this earthworm species; one Ms dissertation was produced, and one undergraduate thesis is likely to be produced. The outcomes of the proposed project may provide basis for mass culture of this species, and may help in developing earthworm farming in Bangladesh, if it is meticulously extended by further research.
