“…The results showed that the apparent IMTA-FCR was 0.90, which is better than the industry standard FCR of 1.50 for intensely commercial tilapia or cat sh monoculture systems 38,49,50 . As a result, the IMTA system appears to be one of the most important strategies to boost feed utilization in aquaculture.…”

Water quality in land-based fish production can be controlled through either instantaneous water exchange or costly wastewater treatment followed by recirculation. Agricultural-aquaculture integration is an excellent alternative technique for lowering nutrient discharge levels, increasing profitability, and transforming fish culture wastewater into valuable products. The current study employed a solar energy system to power two separate IMTA-aquaponics systems (Nutrient Film Technique, NFT, and Floating Raft Systems, FRS) for the cultivation of Nile tilapia, African catfish, thin-lipped grey mullet, freshwater crayfish, freshwater mussels, and a variety of vegetables. Tilapia and catfish were fed exclusively on diets under the IMTA system. All wastewater from tilapia and catfish ponds, including dissolved and solid, flows sequentially to ponds of other cultivated species. The water then flows through the IMTA system's terminal point to the NFT and FRS systems before returning to the tilapia and catfish ponds, with complete control of the nutrient flow throughout this entire circular system. Two 147-day production cycles were carried out. The findings of the second production cycle are presented. Total biomass gain for aquatic species in the IMTA system was 736.46 kg, compared to 145.49 and 271.01 kg in the tilapia and catfish monoculture systems, respectively. The current IMTA system had a cumulative feed conversion ratio (FCR) of 0.90, whereas monoculture systems for tilapia and catfish had FCRs of 1.28 and 1.42, respectively. Nile tilapia and catfish consumed 571.90 kg of feed containing 25.70 kg of nitrogen (N) and 9.70 kg of phosphorus (P), respectively, and gained 11.41 and 3.93 kg of dietary N and P, representing 44.40 and 40.46% dietary N and P retention, respectively. In the IMTA system, the addition of mullet and prawn as detrivores aquatic animals improves dietary N and P utilization efficiency to 59.06 and 51.19%, respectively, and the addition of mussels as herbivore animals improves dietary N and P utilization efficiency to 65.61 and 54.67%, respectively. Finally, the use of FRS and NFT as hydroponic systems increased dietary N and P efficiency to 83.51% N and 96.82% P, respectively. This study indicates that the IMTA-Aquaponic system, as a bio-integrated food production system, can convert the majority of fish-fed residuals into useful products suitable for desert, rural, and urban areas in poor and developing countries.

“…This understanding can lead to the development of more efficient fish capable of utilizing new diets, ultimately improving fish nutrition in the future. By focusing on the nutritional programming of metabolism linked to the early life stages of fish, we can also contribute to the development of sustainable aquaculture practices (Panserat et al, 2019; Aboseif et al, 2022aAboseif et al, , 2022bAboseif & Goda, 2022). Furthermore, the nutritional programming could be employed as a strategy in aquaculture to promote sustainable feeding strategies (Hou & Fuiman, 2020).…”

INTRODUCTIONThroughout the past few decades, the emergence of new scientific challenges to improve fish nutrition and the rapid development of aquaculture production has been observed. Moreover, fish nutrition is vital for the development of a sustainable aquaculture (FAO, 2018). The diet formulations used for farmed fish have been largely modified in the past few years. However, bottlenecks still exist in being able to suppress
