This guide for using bio-slurry for commercial fishponds was developed as part of an experimental study to estimate the effects of using bio-slurry in fish ponds and identify methods for using it. The aim is to carry forth some information to help farmers use bio-slurry from biogas for growth out ponds.

It describes the pond preparation; fingerlings selection; bio-slurry preparation; method of applying the effluent; feed monitoring; pond environment monitoring and fish health.

Bio-slurry from biogas production has many advantages when used in aquaculture (reduced risk of infection in fish; increasing the growth rate of fish because of more effective nutrient enrichment aquatic biota in the pond). The growth rate can increase, and the survival rate of fish as well, while reducing the coefficient of food. As a result, ultimately it increases the economic efficiency of the pond compared to the fresh material used to fertilise ponds.

The Social Inclusion (SI) and Accountability Proofing Tool has been designed to help SNV advisors and other development practitioners consider and adequately address SI and accountability issues while planning, executing, monitoring and evaluating a programme or project. The tool has been structured around three key stages of project management: analysis and planning, implementation and monitoring, and evaluation. Therefore, the use of this tool is intended to be part of and add quality to the programme/project management process.
