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

在人工饲料中添加海葵叶提取物对凡纳滨对虾生长的影响

红树树叶含有丰富的生物活性化合物，可以促进虾的生长。本研究考察了在饲料中添加海葵叶对白对虾生长和FCR的影响，并确定了最佳添加量。以PL-20白对虾种子为试验材料，采用RAL法，分4个处理，3个重复。使用不同剂量的海葵叶提取物:(A) 125 ppm/500 g饲料，(B) 175 ppm/500 g饲料，(C) 225 ppm/500 g饲料(D)。饲料量为每次处理总生物量的3%，每天5次，连续30天。对虾生长的最佳剂量为225 ppm/500 g (D)，绝对生长量为7.71 g, FCR为1.27。然而，处理对虾的SR没有影响，在所有处理中SR都达到100%。水质参数为温度27.4-30⁰C, DO 6.3 - 7.9，盐度13-15 ppt, pH 7.5 - 7.8。关键词:海棠，生长，凡纳滨对虾
