The water source gained directly from sea water comes from Madura Strait by using submersible pump. Whereas water quality which was measured were temperature 30-310C, salinity 32-34, pH 7,9-8,2, nitrit 0,013-0,019 mg/l and ammonia 0,001 mg/l, dissolved oxigen (DO) 4,67-5,64 mg/l. Nursery was started from mouse grouper breed in size of 3 cm or D90 until the size was ready to be placed in KJA (10 cm). The breed in size of nursering were reared in  concretetank with the density of breed was 500-600 breeds / m3. Feed given in this nursery is artficial pellets made from factory. Every 1-2 weeks, grading was undertaken. Grading was undertaken to make the similarity of breed size to decrease competition in gaining the feed.
