This poster details a simple system of improving the quality of fish fry production and distribution from hatcheries using a nylon bag called a hapa, which was suspended in existing water sources. It was found that the hapa system allowed small scale farmers to cheaply and easily intensify production without making extensive changes to existing ponds or rice fields. The scheme has expanded and now encompasses 70 hatchery farmers in 15 districts of nothern Thailand.
