Assessment of primary productivity of integrated multi-trophic aquaculture ponds


Author(s): Nesar Uddin, Abu Syed Md. Kibria and Mohammad Mahfujul Haque

Abstract: Primary productivity in integrated multi-trophic aquaculture (IMTA) systems was investigated in experimental earthen ponds. The experimental design consisted of three treatments (T1, T2, and T3) in triplicate, T1: carps and shing; T2: carps, shing and snail; T3: carps, shing, snail, tilapia and water spinach. Carps, shing and tilapia were fed with a supplementary feed. Five classes and 34 genera of phytoplankton were identified: Chlorophyceae was the most dominant group. Although no significant differences (P>0.05) in abundance of phytoplankton were found, productivity was the highest in T3, average concentration was 43×105±94×104, 36×105±19×105, and 49×105±91×104 cells/l T1, T2, and T3, respectively. Water quality parameters were within the suitable ranges of aquaculture in all treatments, except decreasing temperature in November when phytoplankton production increased. The results suggest that IMTA systems do not change the nature of primary productivity and water quality parameters significantly, and IMTA could be more productive towards increasing nutrition and income of the poor fish farmers.
