Feeds were prepared to be iso-nitrogenous (35.00%±0.20) and iso-caloric (kcal/kg 4700.00±0.52). Proximate compositions of test feeds, fecal matter and chromium contents also were determined. Results revealed the maximum value of ADCs for dry matter (DM) was found in reference feed (68.09%), while the minimum value was found in (test diet 4) 4 (50.36%). Similarly, the maximum ADCs values for crude protein content, gross energy, ether extract and crude fiber were found in control feed, while the minimum values were found in the feed 4. The survival rate was found to be significantly low among studied fish fed with feed 4. The study has shown that red tilapia efficient maximum digestion to nutrients is only up to 20% inclusion of water hyacinth in the feed.

Experimental units were set up with different amounts of supplemented organic and inorganic (complex minerals) nutrients to carry out the study. The results indicated that desirable growth of M. rosenbergii might be possible in RA systems when supplied sufficient levels of macro-micro nutrients. Analyses of nutrients in the prawn culture tanks demonstrated that ammonia and nitrate concentrations were critical in maintaining proper water quality during the culture period. Five-day biological oxygen demand (BOD5) increased significantly with the increased loading of organic supplement in the rearing tanks. A significant linear relationship of chlorophyll a and N:P ratio was observed among the treatments. The combination of complex minerals and organic chicken manure (CM15) displayed a higher N:P ratio, maximal total yield and did not show adverse effects of NH3 concentrations and other important water quality parameters.

The purpose of this study is to improve the available visual IAAS (Integrated Agriculture-Aquaculture System) program for evaluation of freshwater prawn (Macrobrachium rosenbergii) and plant (Lactuca sativa) yields.
