Abstract

The research was held in 14th July  – 20th August 2018. Located in Brackish water Laboratory, Fisheries Faculty of Pekalongan University. The aim of this research is to find out the impact of curcuma to increase the growth and survival rate of Nile Tilapia. The treatment that be implemented was extending dosage of curcuma flour (gram)  in 1 kg of artificial  fish feed, such as followed : treatment A 0 ml ( control), B  9 g  of curcuma, C 12 g  curcuma and D 15 g curcuma. The method used was the Completely Randomized Design Method consisting of 4 treatments and 3 replications. The result which had given from the research was treatment D showed the highest growth.  The average of weight of fish which can be reached by every treatment A, B, C, D as described 3,31 g, 4,77 g, 6,8 g, and 8.04 g, The analysis of result showed that all treatments have different effects for growth of fish. The water quality during the research such as temperature between 27-290 C, pH revolve 7,1-7,3 and the salinity was 16-17 ppt which mean all parameters was supported to fish growth.

Abstract

Mangrove leaves contain abundant bioactive compounds that can optimize the growth of shrimp. This research examined the effect of adding Avicennia marina leaves to feed on the growth and FCR of Whiteleg shrimp and determined the optimal dose. Whiteleg shrimp seeds of PL-20 were used in experiments that employed RAL method with 4 treatments and 3 replications. Different doses of Avicennia marina leaf extract were used: (A) 125 ppm/500 g feed, (B) 175 ppm/500 g feed, (C) 225 ppm/500 g feed (D). The feed amounted to 3% of the total biomass per treatment every day administered in 5 meals daily for 30 days. The most optimal dose for the growth of shrimp was 225 ppm/500 g (D) with an absolute growth of 7.71 g and FCR of 1.27. However, the treatment did not affect the SR of shrimp for its value reached 100% in all treatments. The parameters of water quality were temperature of 27.4–30⁰C, DO 6.3 – 7.9, salinity 13–15 ppt, and pH 7.5 – 7.8. Keywords: Avicennia marina, Growth, Litopenaeus vannamei
