Waste to wealth: A sustainable circular bioeconomy approach of chicken manure powder for increasing productivity of Lanchester’s freshwater prawn (Macrobrachium lanchesteri)

A biorefinery is ideal because it can combine many processes to produce multiple bio-products from organic solid waste. Moreover, in view of socially rising energy demands and biodiversity conservation, contributed as a sustainable strategic tool for the emerging circular bio-economy. In this research objective was study some techniques increase productivity Lanchester’s freshwater prawn earthen ponds. The experiment using completely randomized design conducted. six Nattearthen ponds, different amounts chicken manure were applied phytoplankton (green algae). first pond control, then, 2nd 6th ponds with 30, 60, 90, 120 150 kg/rai/week, respectively. prawns fed twice daily 5% total body weight 40% protein diet. results showed that feeding densities algae) affected Lanchester's significantly. highest 566.30 ±4.88 g kg/rai/week. 0 kilograms/rai/week 416.53 ± 9.89, 295.43 5.46, 281.13 4.63, 275.39±4.78 265.86 ±4.79 g, conclusion, effect increased (Macrobrachium lanchesteri).
