This rice field shown in the photo receives its water from a dam (Rwojya) located in Kirehe. The government stocks the dam with tilapia. The fishermen operating in this dam are the owners of the land used in dam construction. Rice fields receive the fertile water from Rwojya dam and hence enhance rice productivity as well as production economics. There are two cooperatives involved; the first is for fishermen while the second is for rice farmers.

The photo shows the market display of snake skin gourami (Trichogaster pectoralis) in a Thai fish market. The freshwater species enjoys a high consumer preference in its salted-dried form. Drying is often carried out as sun-drying while some producers use hot air drying. Aquaculture is the only source of this species. Market price is 150-200 baht/kg (5-8 US$) based on fish size as well as the moisture content of dried product.
