Abstract:

An experiment was conducted for 160 days to culture tubificids (aquatic oligochaetes) in a medium containing 35% wheat bran, 25% cow dung, 20% mustard oil cake and 20% fine sand under running water in outdoor culvert (160 x 25 x 10 cm). A harvesting schedule of four different quantities was tested to obtain a sustainable yield. A harvest level of 30 mg.cm^-2every 10 days was more sustainable and significantly (P<0.01) better than other levels tested, with total production of 852.42 ‡ 4.13 mg-cm^-2 of tubificids.
