| Abstract | This study was conducted to investigate the potential utilization of fish feed particulate waste by freshwater mussels of Aspatharia chaiziana and Aspatharia marnoi (Family: Iridinidae) cultured in an integrated multi-trophic aquaculture (IMTA) system. The utilization of fish feed waste was assessed using some indicators related to growth performance and proximate composition, to evaluate if co-cultured freshwater mussels enhanced their IMTA system. Physical properties data for several cooked forms and processing methods of mussels was evaluated. The results showed that the net biomass production of Nile tilapia, Nile catfish, thin-lipped grey mullet, prawn and freshwater mussels in IMTA system are 327.63, 273.8, 96.76, 19.67 and 188 kg/6 month. The combination of Nile tilapia and catfish with thin-lipped grey mullet and prawn as detritivorous fish, increases dietary nitrogen (N) and phosphorous (P) utilization efficiency to 17.49 and 24.44%, respectively. By Added freshwater mussels in the system as herbivore consumption, increased dietary efficiency of N and P by 12.67 and 19.89%, respectively. Finally, dietary N and P efficiency increased by addition hydroponic systems (HS) by 35.76 and 44.31%, respectively. In the present study, Metals bioaccumulation in the flesh mussels did not exceed the permissible limits set for heavy metals. Therefore, these mussels in this study did not pose any threat to human upon their consumption. Concerning the effect of applied cooking methods (boiled, fried, steaming and France sauce, respectively), on mussel's values contents of Trimethylamine-nitrogen (TMA-N), total volatile basic nitrogen (TVB-N) and thiobarbituric acid (TBA) was decreased. Appearance scores for all cooked methods samples slightly increased than taste scores; while the odor and tenderness of the boiled and steaming mussel samples received a lower score than other cooked methods. The limit of acceptability (score lower than 6) for juiciness was recorded for fried mussel samples only. This result indicates that IMTA as a bio-integrated food production system is not only a successful method for biomass production as food crops, but also a useful system to recycle aquaculture wastewater and it is applicable to desert, rural and urban area in development countries. |
