This report reviews the production systems and practices of tilapia broodstock production in sewage ponds in southern Vietnam. Interviews were carried out with hatchery operators to gather information on the source of seed, broodstock and nursery management. The survey covered both socioeconomic and technical issues relating to the quality of fish seed. The report concludes that to fulfill the potential demand for high quality tilapia fry, a larger scaling up in the capacity of hatcheries will be needed.
