Extract

Fishery in the village irrigation-tanks has long played an important role as a source of food in the traditional villages in the Dry Zone comprising two-thirds of the area of Sri Lanka. Therefore, the villagers have traditionally developed various management practices which lead to sustainable utilization of fishery resources. This study is an attempt to explore such practices pertaining to fishery in the irrigation systems in the traditional villages and to investigate their relevance to designing appropriate resource-management systems leading to ecologically sustainable development. The study indicates that the traditional practices which contribute to the sustainable utilization of fishery resources are fourfold: (1) ecological, (2) technological, (3) institutional, and (4) cultural.

The ecological set-up of the irrigation system of any given traditional village has evolved in such a way that it could facilitate the survival of fishes during the dry season, which is the major threat to their continuous survival. Though all small tanks dry out during the dry season, small amounts of water remain in some big tanks. As all tanks in any given catchment area are interconnected, the fishes remaining in the big tanks can migrate to the small tanks at the beginning of the rainy season and so re-colonize them. While the buffalo wallow which is located at the lower end of the paddy tract acts as a drought refugium, the natural vegetation-cover associated with the irrigation system provides food, a favourable microclimate, and materials required for the construction of nests by those fishes that make them.
