“…Metal contamination in the Hainan mangroves is mainly from aquacultural sewage and agricultural runoff (Li et al, 2022), which may lead to the increased availability of nutrients with a concomitant increase in species richness (Grall and Chauvaud, 2002). The presence of these nutrients at low concentrations does not affect the macrofauna, which may even benefit from the additional supply (Ribeiro et al, 2016); however, an oversupply of nutrients will cause an opposite effect (Giles, 2008), especially in species with low tolerance to stressful conditions (Weisberg et al, 1997;King et al, 2005).…”

Few studies have systematically assessed the ecological status of mangrove wetlands following the stress of anthropogenic activities in China. This study investigated the spatial and seasonal distribution of benthic macroinvertebrate communities and assessed the ecological quality of mangrove habitats on an island scale in Hainan, China (containing the third largest mangrove area of China and the highest mangrove species richness). For the benthic macrofauna community structure, a total of 102 macrobenthic taxa belonging to 50 families were identified, with Crustaceans, Molluscs, Polychaetes, and Oligochaeta having relative abundances of 52.3%, 36.1%, 10.8%, and 0.8%, respectively. Decapoda and Gastropoda dominated the benthic community abundance. Non-metric multidimensional scaling and an analysis of similarities revealed significantly different macroinvertebrate assemblages among the regions during the two seasons. The South mangroves had the lowest macrofauna species numbers, biodiversity, richness, and abundance. The macrofaunal species richness, Shannon index, Margalef index, abundance, and biomass markedly affected by region and season. As indicated by the biotic indices AMBI (AZTI’s Marine Biotic Index) and M-AMBI, more than half of the mangrove habitats on Hainan Island were slightly to heavily disturbed and had poor to moderate ecological quality. Our results recommend long-term monitoring for evaluating the quality status of mangrove wetlands and avoiding extensive land-use conversion of mangroves. Holistic approaches considering ecological characteristics and combining information on both floral and faunal functionality would contribute to the effective management and conservation of mangroves in disturbed areas.

“…chemical, metallurgy, cosmetic, beverages, among others. Since then, the anthropogenic pressures in BTS increased progressively and several activities have been influencing the environmental quality of the Bay, such as terrestrial run off, shrimp farming, inputs of industrial and untreated domestic effluents, solid wastes, mining and intense harbor activities (Beretta et al, 2014;de Souza et al, 2011;Hatje et al, 2006;Hatje and Barros, 2012;Ribeiro et al, 2016).…”

“…The Todos os Santos Bay (BTS), northeast Brazil (Figure 1), is located in the vicinity of Salvador, the third largest metropolitan area in Brazil, with a population of 2.9 million (IBGE, 2016). Since the construction of the Landulpho Alves Mataripe refinery (RLAM) and the petrochemical complex, the bay has experienced a series of environmental pressures that impacted negatively the environmental quality, biodiversity and ecological services of the bay (de Souza et al, 2011;Hatje et al, 2016Hatje et al, , 2006Hatje and Barros, 2012;Ribeiro et al, 2016).…”

The evolution of the impacts of anthropogenic activities in Todos os Santos Bay was evaluated by profiles of trace metals and Pb isotopes determined in sediment cores. Fluxes of metals increased up to 12, 4 and 2 times for Cu, Pb, and Zn, respectively, compared to those recorded in the beginning of the 20 century. Stable Pb isotopes identified a decommissioned lead smelter and burning of fossil fuels as the main sources of Pb. Most metals showed minor to moderate enrichment factors (EF<4), but Cu and Pb were highly enriched (EF=28 and 6, respectively) at the Aratu harbor. Temporal changes in sediments were associated to different activities, namely Pb smelting, burning of fossil fuels, maritime traffic, petroleum related activities, inputs of domestic effluents, and changes in land uses. The effects of the implementation of environmental policies to improve the waters of the bay could not be identified in the evaluated cores.

“…In addition to producing organic waste, aquaculture systems also have an impact on the benthic environment [13]. In the study [13], the presence of organic waste will affect the nutrient cycle in the benthic environment and the relationship between sediment quality and the presence of benthic macrofauna in shrimp farming. Benthic macrofauna or so-called macrobenthos are basic aquatic organisms, in the form of animals and plants that live on the bottom surface or at the bottom of the waters [14].…”

In the shrimp pond aquaculture system, metabolic waste in the form of unfeed pellets and shrimp excretion can reduce water quality and increase both soluble organic matter in waters and organic deposition to sediments. A developed dynamical system was formed based on the interactions that occur between phytoplankton growth, macrobenthos density, and sediment in response to nitrogen and phosphate concentrations. The purpose of this research was to analize the stability of the proposed dynamical system. Furthermore, we determine the level of water quality in the aquaculture system based on the interaction between four variables, i.e. nitrogen, abundance of phytoplankton, abundance of macrobenthos, and sediment properties. The Lyapunov stability theory using the Gradient Variable method was used to determine the global stability of the systems. Assumption of this method is determine and for gradient variable function. In the Lyapunov function, if the value of the scalar function is definite positive and its first derivative is definite negative, then the system is globally asymptotically stable. Based on mathematical analysis and numerical simulation, the shrimp pond dynamical system model in BBPBAP Jepara, Indonesia was globally asymptotically stable at equilibrium point.
