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.
