The catfish Mystus gulio is a small indigenous euryhaline fish found in fresh and brackishwater environments of the Sunderban delta of Bangladesh and India. A fast-growing species with high nutritional value, market demand and hardy nature, M. gulio is a desirable candidate for aquaculture in Asia. It is co-cultured with other brackishwater species in paddy fields, but expansion of culture in pond systems has been held back because of a shortage of seed. This article reports on induced breeding techniques and the development of a farmer-friendly modular hatchery and farming system suitable for use at the homestead level or by small-scale operators.
