Nilem (Osteochilus hasselti) is one of endemic fish Indonesia especially at West Java region living in fresh water. Nilem having a similar to the carp, because the fish still in the same family to the carp. The advantage of nilem not only of the nutrition, but also because of price is very affordable and very popular by the community in West Java. Field Work Practice was held in the “Balai Pengembangan dan Pemacuan Stok Ikan Gurame dan Nilem (BPPSIGN) Tasikmalaya, Jawa Barat” on January 23th , until February 23th, 2017. The working method used in the Field Work Practice is by following the nilem fish enlargement activity starting from the preparation of ponds, the provision of aquaculture water, the source of the water used and the stocking of nilem seeds in the “Balai Pengembangan dan Pemacuan Stok Ikan Gurame dan Nilem (BPPSIGN) Tasikmalaya, Jawa Barat”. The results of the field work practices on the grow out technique of nilem fish is started from the preparation of ponds, the pond condition must cleaned, soil reversal, pond drying for 5 - 7 days, then do salting and liming with a ratio of 1: 1 and each dose of 75-100 gram / m2 and left for 5 days. Furthermore, water is flowed from the filter basin to the pond until the height of 100-120 cm. Restocking done in the morning to avoid stress fish. The fish seed are obtained from own hatchery, within a size of 5-6 cm in the phase of the third nursery. Feed is given twice daily, in the morning and sick days with a dose of 1.45 kg each time. The water source that used on enlargement nilem pond derived from the Cipakat river irrigation channel and when entering the dry season using wellbore. The water quality parameters measured every once a week. The average temperature for nilem between 23,140 C - 27,730 C, the average pH is 6.22 and the average DO is 5.45 mg / l. At the field work practice we are not to do the water replacement of pond because, the condition of organic matter sorted not excessive, so can not be mortality in fish. This is because the density of fish is not fully effective in pond. Pests and diseases prevention of nilem are done by the provision of babadotan plants (Ageratum conyzoides) and jarong (Achyranthes aspera) in the preparation of the pond and the provision of sente leaves (Alocasia macrorrhiza) and cassava leaves (Manihot esculenta) at the time of sudden death.
