Abstract | Because the government of Myanmar is developing a mega scale agriculture projects in flood plain areas and wet land areas, wild seed supply is expected to decrease rapidly in foreseeable future. Hatchery seed production has played an important role in aquaculture development. The role of hatcheries has not been documented yet in Myanmar in terms of its ability to supply seed. Little is known about the hatchery practices, nursing practices and seed production levels. This survey was conducted in rural and peri-urban areas in nine townships of Yangon Division to evaluate existing fresh water fish seed production of five species: Rohu, Common carp, Catla, Catfish and Tilapia. The use of technology, production levels, infrastructure and institutional support were surveyed. The technicians and labor availability as well as their knowledge of hatchery practice was assessed. Rohu, Catla and Catfish fish seed of the target species were produced by using pituitary glands for induced breeding of fish at the majority of hatcheries in the study areas. Many hatchery operators reported that they did not have the training in use of synthetic hormone. Common carp fish seed is produced only natural spawning In this study, low quality and poor survival rate were the most critical determinants for the high stocking rate at the initial period of pond production cycle. High stocking at initial period is to compensate the seed loss due to stocking of low quality and poor survival of the fish seed. The technicians 35 and labors 194, working in 28 hatcheries at the study areas are also owners of their hatchery. The private Catfish hatcheries in the peri urban areas are operated by family members that do not need more labors while other hatcheries especially private Rohu and Common carp hatcheries in the urban areas need to hire labors. Hatchery facilities seem inadequate. Equipments and chemical in the majority of hatcheries in the rural areas are lacking. The poor extension services and financial support by the government to develop private and institutional hatcheries were apparent. The survey also showed that fish seed may be adequate in the study area and hatchery fish seed production has improved due to increasing number of grow out ponds and reduce wild seed availability. In addition, government support is insufficient which seems to have impeded the aquaculture development in Myanmar. |
