Abstract

Aquaculture has been recognized to play a vital role in food production to support the expanding global human population. However, concerns over the negative environmental impacts of aquaculture have made integrated multi-trophic aquaculture (IMTA) receive increased attention. A study on the pond environment was conducted to show the distinction between primary and secondary productivity in a typical IMTA system and a monoculture system. The paper focused on the abundance of phytoplankton, zooplankton, benthic macroinvertebrates, and sediment quality in monoculture and IMTA treatments assessed through morphological analysis using marine shrimps (Penaeus indicus) integrated with sea cucumbers (Holothuria scabra) and cockles (Anadara antiquata). Results of microscopy analysis revealed the occurrence of 5 phytoplankton classes. Bacillariophyceae was the dominating class consisting of 13.04 ± 20.62 cells/m3 in IMTA treatment and 6.57 ± 17.84 cells/m3 in monoculture treatment. Among the zooplankton, the class Maxillopoda had the highest abundance of zooplanktonic organisms at 930 ind./m3 for IMTA and 390 ind./m3 for monoculture. Naididae family was the most dominant among benthic macroinvertebrates having an abundance of 8.9 ind./m 2 for IMTA and 3.4 ind./m2 for monoculture treatment. Sediment quality evaluated the environmental conditions of both systems. The findings of this study show that IMTA may lead to better utilization of pond communities to improve pond productivity further.
