Utilization of crude palm oil as a fish feed ingredient has been carried out in recent years. Crude palm oil can replace fish oil on dietary fish. The use of CPO has been applied to barramundi (Lates calcarifer), Rainbow Trout (Oncorhynchus mykiss), Japanese sea bass (Lateolabrax japonicas), salmonid species, and Nile tilapia (Oreochromis niloticus) diets. palm oil appears to boost protein efficiency when being added to oxidized fish feed. The various advantages of palm oil include superior energy sources (saturated and monounsaturated fatty acids), high content of natural antioxidants (carotenes and E vitamin), lessening fatty acid deposition, and low cost and producing high oil yield. Moreover, palm oil-based diets for fish indicated no effect on the fillets either in their texture or color Fish growth is not disturbed if you change fish oil to crude palm oil in fish feed. The level of use of palm oil is different for each fish species.

“…A conceptual framework known as the water-energy-food (WEF) nexus acknowledges the interdependencies and connections between water, energy, and food systems [1,2]. It emphasizes the necessity for integrated and sustainable management techniques and draws attention to the complex relationships and trade-offs among various areas [3,4]. Water is necessary for many human activities, such as residential use, industry, and agriculture.…”

Due to their toxicity, Cr(VI) levels are subject to strict legislation and regulations in various industries and environmental contexts. Effective treatment technologies are also being developed to decrease the negative impacts on human health and the environment by removing Cr(VI) from water sources and wastewater. As a result, it would be interesting to model and optimize the Cr(VI) removal processes, especially those under neutral pH circumstances. Microbial fuel cells (MFCs) have the capacity to remove Cr(VI), but additional research is needed to enhance their usability, increase their efficacy, and address issues like scalability and maintaining stable operation. In this research work, ANFIS modeling and artificial ecosystem optimization (AEO) were used to maximize Cr(VI) removal efficiency and the power density of MFC. First, based on measured data, an ANFIS model is developed to simulate the MFC performance in terms of the Cu(II)/Cr(VI) ratio, substrate (sodium acetate) concentration (g/L), and external resistance Ω. Then, using artificial ecosystem optimization (AEO), the optimal values of these operating parameters, i.e., Cu(II)/Cr(VI) ratio, substrate concentration, and external resistance, are identified, corresponding to maximum Cr(VI) removal efficiency and power density. In the ANFIS modeling stage of power density, the coefficient-of-determination is enhanced to 0.9981 compared with 0.992 (by ANOVA), and the RMSE is decreased to 0.4863 compared with 16.486 (by ANOVA). This shows that the modeling phase was effective. In sum, the integration between ANFIS and AEO increased the power density and Cr(VI) removal efficiency by 19.14% and 15.14%, respectively, compared to the measured data.

“…Li et al 7 developed a network DEA model for assessing the efficiencies of WFEE nexus in 13 cities of China; the results indicated that environmental governance and policy intervention have a positive effect on the improvement of the system efficiency. Rubinsin et al 8 used AHP for investigating interlinkages between the WFEE nexus in the biomass value chain, where the priorities of the environmental and economic impacts were evaluated based on experts' judgements. Although the above studies were effective for quantitatively analyzing WFEE nexus, most of them focused on deterministic analyses which could encounter difficulties in reflecting complexities and uncertainties existed in the nexus system.…”

A copula bi-level fractional programming (CBFP) method is developed for planning the water–food–energy–ecology (WFEE) nexus system. CBFP has advantages in (i) dealing with ratio-objective problems, (ii) balancing the conflicts between hierarchical decision levels, and (iii) reflecting joint risks of correlated uncertain variables. Then, a CBFP–WFEE model is formulated to the Ili-Balkhash basin in Central Asia, in which 108 scenarios associated with different irrigation efficiencies, ecological-flow demands (EBW), and water–land resources have been examined. Solutions of water allocation, hydropower generation, and land-use pattern are obtained. Our major findings are as follows: (i) from 2021 to 2050, water allocation to livestock in East Kazakhstan would remarkably increase (by 40.9%) when water allocation to food is satisfied; (ii) hydropower generation would increase with the rising ecological flows and arable land resources; (iii) EBW is the key factor influencing the water inflow to the Balkhash Lake; (iv) the share of ecosystem water allocation would exceed 17.5% by 2050, and grassland area would rank in the first place of the ecosystem. Compared with conventional bi-level stochastic programming and single-level fractional programming models, the CBFP–WFEE model can achieve a higher ecosystem service value and higher efficiency of water–land resources, which can provide more feasible and sustainable alternatives for the WFEE nexus system. The obtained results can help balance the contradictions among water shortage, economic development, and ecology protection, as well as provide synergic management strategies for regional sustainability.
