“…Eutrophication in lakes and reservoirs is rapidly increasing due to excessive discharge of nutrient-rich effluents originating from industry and agriculture in basin areas [11][12]. Primary production in terms of Chl-a production is a commonly used surrogate of eutrophication that is mainly based on phosphorus and nitrogen availability [13], and Carlson [14] has developed the trophic state index (TSI) for the assessment of eutrophication that is primarily based on Chl-a level in a water body.…”

During the past few decades, freshwater resources are subjugated to increasing anthropogenic activities such as the construction of reservoirs for accruing the benefits of power generation, municipal water supply for drinking and household, transportation, flood control, recreation, agriculture, fishing [1], aesthetics, raising aquatic animals, and so on. Due to natural flow manipulations coupled with intensive rainfall [2], degradation of physiochemical water quality is very recognizable [3], besides trophic disarrays such as oligotrophy due to higher water retention time and

“…The TLI values of all aquaculture ponds peaked in August. Temperature is considered to be one of the primary factors determining the seasonal dynamics of eutrophication levels [43] . However, the trophic levels of pond II were notably lower than pond I, indicating that the polluted sediment had been gradually restored by the application of immobilized EM combined with sediment aeration.…”

The endogenous release of nitrogen and phosphorus from aquaculture sediment can continuously pollute the water quality in aquaculture ponds. In this study, an integrated bioremediation approach that combined effective microorganisms (EM) with aeration techniques was designed to restore contaminated aquaculture sediment. Initially, a set of laboratory-scale experiments was designed to evaluate the feasibility of the technology for the bioremediation of nitrogen and phosphorus. The removal and transformation efficiency indexes of both the overlying water and sediment were measured. From the obtained results, the combination of sediment aeration and immobilized EM significantly improved the nitrogen and phosphorus removal rate from the overlying water and sediment when compared to other methods. Subsequently, a series of field-scale experiments was further implemented to assess the integrated technique in practical applications. In field experiments, the variation in the comprehensive trophic level index (TLI) and sediment biodegradation activities (G value) was used to assess the effect of sediment bioremediation. In pond II which promotes sediment biodegradation, the values of TLI varied from 70.13 to 54.16, and the classification level changed from Hypereutrophic to a Light eutrophic. In addition, the G value increased from 0.98 kg/(kg•h) to 2.12 kg/(kg•h). The organic matter (OM) and sediment thickness (ST) decreased by 17.4 g/kg and 2.3 cm, respectively. The obtained results indicated that the combination of EM and sediment aeration might be feasible and effective for the remediation of nitrogen-and phosphorus-polluted aquaculture sediment.

“…In this way, ecological modelling can be used to understand several environmental conditions, allowing the prediction of the future state of aquatic ecosystems submitted to some environmental/anthropic stress. This predictive capacity is particularly important in tropical continental environments, which are naturally vulnerable ecosystems with a high risk of environmental degradation (GUO et al, 2018).…”

Continental aquatic ecosystems play a fundamental role in economic and social development; however, they are vulnerable to environmental degradation due to the various stresses to which they are submitted. Aquaculture is among the main anthropic activities that influence these environments. Mathematical modelling of aquatic ecosystems performed using a set of computational tools allows simplified representation of environment regarding its biotic and abiotic components. Some of the most used techniques are: hydrodynamic modelling, focusing on the dispersion of nutrients; nutrient-mass balance modelling, especially phosphorus; bioenergetic modelling in animal production systems, with an estimate of the generation of residues in the environment by farmed animals; and trophic and ecological modelling, focusing on aquatic communities and their interactions. These techniques help understand changes caused by aquaculture systems in aquatic environments. In this way, it is possible to estimate the magnitude and extent of the impacts of these activities by simulating the possible environmental changes over time. It can be concluded that techniques involving mathematical modelling can provide relevant information for future impacts prediction on aquatic environments, promoting the management of water resources and their multiple uses.
