    The aims of this study were to describe both the role of small-scale freshwater aquaculture practices and the livelihood of fish farmers in Indonesia. Focusing on freshwater aquaculture, aquaculture practices and fish farmers’ capital (livelihood) were compared based on 3 types of pond practices, i.e., raceway, excavated, and paddy field ponds. The impacts of aquaculture practices on the environment (water quality) were also examined. Data were collected from 98 fish farmers (households) in West Sumatra province using structured questionnaires, and water quality was analyzed using 15 outlet-water samples from 3 kinds of ponds. Results showed that the excavated pond farmers had better livelihood capitals than the other types of pond farmers. Fish production in raceway ponds was generally higher than excavated and paddy field ponds, but many limitations were observed in the raceway-culture. The main problem among raceway pond and paddy field farmers was the high price of feed, while that of excavated pond farmers was a high cost of pond construction. In the dry season, most of the water quality variables of the three types of ponds were significantly different from those in the rainy season. Some variables of water quality (chemical oxygen demand (COD) and nitrite, in particular) exceeded the safety level of good aquaculture practices in all types of ponds, and this may result in public concern in the near future. Generally, the water quality of raceway ponds was better than that of other pond types.
