Pond water quality and its relation to fish yield and disease occurrence in small-scale aquaculture in arid areas.

The study was conducted to determine the associations between water availability and management practises with pond water parameters in small-scale aquaculture in arid areas. Further, the study determined the associations between fish yield and disease incidence with the pond water parameters. We visited 36 tilapia farmers in Dodoma, a semi-arid region in Tanzania, for interviews and measurements of pond water parameters.
