Stripped catfish seed has long been produced in Indonesia. However, it still uses silk worms (Tubifex sp) as one feed and no substitution until today. While silk worms (Tubifex sp.) can not be produced economically. During this time, Tubifex obtained from nature so that its availability fluctuated because it is influenced by the season. Therefore, the amount, timing and location of stripped catfish seed production is strongly influenced by the availability of Tubifex sp. Therefore, it is necessary to develop a seed production technique of stripped catfish without using silk worms (Tubifex sp.) Stripped catfish seed so that can be produced throughout the year, the amount in accordance with the needs and close to the raiser location. In an effort can be done to eliminate the dependence on  silk worms (Tubifex, sp.) is rearing the larvae in the nursery pond (outdoor pond). The pond is used for nursery had been prepared so that natural food can grow to the maximum and minimum presence of predators. The larvae are stocked into the pond are 7 days-larvae and 1 day-larvae. Stocking density of 7 days-larvae is 300 larvae / m2.  While stocking density of 1 day larvae is 400 larvae/m2. The average survival rate of 7 days-larvae is 73.01 ± 11.52%. While the survival rate of 1 day-larvae is 55.44 ± 24.98%. Thus, reared 7 days larvae at the pond could be one solution in seed production stripped catfish without silk worms (Tubifex sp.) While reared 1 day-stripped catfish larve in the pond is promising technology but need further development.
