Abstract

This research aims to determine the effects of mangrove (Rhizophora mucronata and Avicennia alba) leaf litter on the water quality, growth, and survival of tiger shrimp, Penaeus monodon post-larvae (PL-60). Three levels of mangrove leaf litter, 0.125 g/L LS, 0.25 g/L LS, 0.5 g/L LS; 0.125 g/L TD, 0.25 g/L TD, and 0.5 g/L TD, were placed directly (LS) and placed in separate aquariums (TD) during post-larvae rearing. The post-larvae-fed pellets constituted 20% of the total biomass, with two daily frequencies. Ammonia, nitrite, total organic matter (TOM), phosphate, Vibrio, and total bacteria in water and sediment, as well as chlorophyll-a, were monitored every 10 days during a 1-month study. The highest ammonia was detected in the 0.5 g/L LS R. mucronata and A. alba leaf litter, whereas nitrite was detected in the 0.5 g/L TD R. mucronata and 0.125 mg/L LS A. alba leaf litter. TOM concentration > 25 mg/L in all the treatments. The highest phosphate coincided with the highest chlorophyll-a on day 20. The lowest total Vibrio in the water was found in the 0.5 g/L LS R. mucronata and A. alba leaf litter, whereas the sediment was found in the control treatment. The total bacteria in the sediment reached 10⁶ CFU/mL in the R. mucronata and A. alba leaf litter. A high tannin concentration was detected in the treatment where the mangrove leaf litter was directly placed, and it had a significant effect (p < 0.05) on post-larvae growth, survival, and production. The lowest post-larvae growth was found in the 0.5 g/L TD R. mucronata treatment. The lowest survival rate for post-larvae was found in 0.5 LS R. mucronata treatment.

红树林落叶对老虎虾（Penaeus monodon Fabricius, 1798）后期幼体的水质、生长和存活的影响

本研究旨在确定红树林（Rhizophora mucronata 和 Avicennia alba）落叶对老虎虾（Penaeus monodon post-larvae，PL-60）的水质、生长和存活的影响。在幼体饲养期间，将 0.125 g/L LS、0.25 g/L LS 和 0.5 g/L LS；0.125 g/L TD、0.25 g/L TD 和 0.5 g/L TD 三种红树林落叶直接放置（LS）和放置在不同的水族箱中（TD）。幼体后投喂的颗粒占总生物量的 20%，每天投喂两次。在为期 1 个月的研究中，每 10 天监测一次水中和沉积物中的氨氮、亚硝酸盐、总有机物（TOM）、磷酸盐、弧菌、细菌总数以及叶绿素-a。在 0.5 g/L LS R. mucronata 和 A. alba 落叶植物中检测到的氨最高，而在 0.5 g/L TD R. mucronata 和 0.125 mg/L LS A. alba 落叶植物中检测到的亚硝酸盐最高。所有处理中的 TOM 浓度均为 25 mg/L。第 20 天，磷酸盐含量最高，叶绿素-a 也最高。水中的弧菌总数在 0.5 g/L LS R. mucronata 和白藜芦醇叶屑中最低，而沉积物中的弧菌总数在对照处理中最低。在 R. mucronata 和 A. alba 落叶植物中，沉积物中的细菌总数达到 106 CFU/mL。在直接投放红树林落叶的处理中检测到了高浓度的单宁酸，它对幼体后期的生长、存活率和产量有显著影响（p < 0.05）。在 0.5 g/L TD R. mucronata 处理中，幼体的生长速度最低。0.5 LS R. mucronata 处理的幼体存活率最低。

期刊介绍： Aquaculture International is an international journal publishing original research papers, short communications, technical notes and review papers on all aspects of aquaculture. The Journal covers topics such as the biology, physiology, pathology and genetics of cultured fish, crustaceans, molluscs and plants, especially new species; water quality of supply systems, fluctuations in water quality within farms and the environmental impacts of aquacultural operations; nutrition, feeding and stocking practices, especially as they affect the health and growth rates of cultured species; sustainable production techniques; bioengineering studies on the design and management of offshore and land-based systems; the improvement of quality and marketing of farmed products; sociological and societal impacts of aquaculture, and more. This is the official Journal of the European Aquaculture Society.
