The Tiger shrimp (Penaeus monodon) was the leading commodity in order to improve Indonesia's shrimp exports. One of the problems today's the shrimp farming is broodstock limitations because it only get up the natural stock, while the need broodstock increased for disease free . The limited number of broodstock from the sea can be overcome by maintaining broodstock in ponds because its potential is quite large in generating prospective broodstock candidate. Maintenance of broodstock in ponds is done to ensure the availability of brood as needed. Based on this reality, the supply of tiger shrimp broodstock in ponds be a right choice.

This research was conducted at 2 ponds of land with an area of each 2,500 m2, which is then partitioned into two portions being replicates in the study. Then performed the pond preparation, includes drying, repair construction, processing of land, fertilizer and water filling, then dotted tiger shrimp juvenile was 22 days (average weight of 0.02 g/ind). The treatments that are : A) stocking 5 ind/m2 and B) stocking 10 ind/ m2.

Observation of biological variables such as body weight were measured every two weeks.

Observation of water quality variables such as temperature, salinity, pH, soluble oxygen and brightness was measured in situ, while ammonia, nitrite, BOT, alkalinity and plankton were observed every 2 weeks. Shrimp survival rate calculated at the end of the study.

The results showed that the production of tiger shrimp broodstock can be done in the pond with a density of 5-10 individuals / m2. The density of 5 individuals / m2 tiger shrimp broodstock candidate growth reaches a weight of 20.5 g / ind., within 60 days of maintenance, while the density of 10 ind. / m2 growth of black tiger shrimp broodstock weight average is only 12.56 gr/ind. with the same of time maintenance.
