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 (Feed Convention Ratio) of Vanname shrimp and determined the optimal dose. Vanname 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. The statistical analyze showed that the F count is greater than F table which is mean the treatments have had a significant effect on growth. However, the treatment did not affect the survival rate (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.
