The research was conducted from September 2017 to November 2017 in Tambak Bulusan Village, Demak, Central Java. The material used is seaweed. Tiger shrimp used in size PL 30 measuring 2.0-2.9 cm. In length the stocking density is 80 individuals/m. The feed used is pellets given by using a fixed feeding rate of 5%. This research used an experimental method with complete randomized design with 5 treatments and 3 replications. The treatment of seaweed stocking used is 50 g, 100 g, 150 g, and 200 g. The results showed that different stocking of seaweed had significant effect on growth of weight, relative growth rate, survival rate of tiger shrimp. The best treatment of seaweed density is treatment A1 (50 gram), treatment A1 can increase the value of tiger shrimp growth with absolute weight of 1.67 ± 0.05 gram; the relative growth rate of 36.36 ± 1.04 %; and the survival rate of 78.75 ± 1.25 %. While the best growth value of seaweed is at treatment A1 (50 gram) with weight growth value of 73,21 ± 4,26 gram, and daily growth rate of 2,15 ± 0,08 %/day. Seaweed can balance the quality of waters with the results of nitrate water quality of 0.02 mg / L - 0.08 mg / L, nitrites of 0.00 - 0.42 mg / l, and ammonia levels of 0.02 - 0.59 mg / l. The results are quite feasible for shrimp farming activities.
