The release of nutrients and anti-nutrients from mangrove leaf litter plays an important role in the biogeochemical cycling in aquatic environments and directly or indirectly affects water quality and food availability to shrimp. In this study, we assessed nutrient and anti-nutrient loss during decomposition of leaf litter at a concentration of 1 g/L for four mangrove species (Avicennia officinalis, Heritiera fomes, Sonneratia apetala, Sonneratia caseolaris) to monitor water quality and to estimate how leaf litter influences shrimp post larvae (PL) growth and survival. There were significant differences (P < 0.05) between the studied species in terms of mass loss of the leaf litter during the investigation period. There were also significant differences (P < 0.05) between the studied species in terms of loss of nutrients and anti-nutrients in the shrimp PL rearing tank during the four-week experimental period. Decomposing mangrove leaves stimulated availability of natural food for shrimp PLs. There was a strong positive correlation between mass loss and PL production. At the concentrations of leaf litter used, the anti-nutritional factors did not affect the PLs. PL survival with mangrove leaf litter was 75–82%, whereas all the PL died without any leaf litter. PL weight gain ranged from 0.83–3.33 mg/d where S. apetala leaf litter resulted in the highest PL growth rate, followed by A. officinalis, S. caseolaris and H. fomes, in that order (P < 0.05). Overall, mangrove leaf litter had a positive effect on shrimp performance in terms of growth and survival and this effect was highest for S. apetala leaf litter.

红树林枯枝落叶中养分和抗养分的释放在水生环境中的生物地球化学循环中起着重要作用，并直接或间接影响虾的水质和食物供应。在这项研究中，我们评估了4种红树林物种（Avicennia officinalis，Heritiera fomes，Sonneratia apetala，Sonneratia caseolaris）在凋落物分解过程中养分和抗养分的损失，浓度为1 g / L，以监测水质并评估如何凋落物影响虾幼虫（PL）的生长和存活。有显着差异（P 在研究期间，根据叶片凋落物的质量损失，研究物种之间的差异<<0.05）。 在四个星期的实验期间，在虾PL饲养池中，营养成分和抗营养成分的损失在被研究物种之间也存在显着差异（P <0.05）。分解红树林的叶子刺激了虾PL天然食物的供应。质量损失与PL产量之间存在很强的正相关关系。在使用枯叶凋落物的浓度下，抗营养因子不影响PL。红树林凋落物的PL存活率为75-82％，而所有PL死亡时都没有任何凋落物。PL增重范围为0.83–3.33 mg / d，其中S. apetala凋落物导致最高PL生长速率，其次是A.巴戟，海桑和H.腐，以该顺序（P  <0.05）。总体而言，红树林凋落物对虾的生长和存活具有积极的影响，而这种影响对于S. apetala凋落物来说是最高的。
