“…Paddy fields that had been continuously flooded had improved soil reduction status, which changed Fe 3+ into Fe 2+ , and Mn 4+ into Mn 2+ (Dong et al, 2021; Yuan, Wang, Li, & Cao, 2020). In this study, the content of soil Fe 2+ and Mn 2+ in the RC farming system was significantly higher than RM system, mainly because the RC system was flooded during the rice and non‐rice seasons to provide a place for crayfish activity (Dien et al, 2019; Sun et al, 2021). High soil C, N, and P concentrations increase microbial biomass in paddy soils (Du et al, 2020).…”

Rice‐crayfish (RC) integrated cultivation, as a sustainable agricultural system, could significantly improve soil fertility. However, the soil quality under the long‐term RC farming system is still unclear. To examine the effects of RC cultivation on soil quality in paddy fields, this study utilized an integrated soil quality index (SQI) for examining the soil quality at different soil profiles (0–10, 10–20, and 20–30 cm depth) in rice monoculture (RM) and RC farming systems (after 1, 6, 10, and 15 years) scattered in Nanxian County, Hunan Province, China. The minimum datasets for evaluating soil quality were assembled using the soil pH, bulk density, total nitrogen, microbial biomass carbon, microbial biomass nitrogen, and β‐d‐glucosidase. The findings demonstrated that soil quality was greatly impacted by RC farming, which improved with the increase of years under RC management. The soil quality of 10‐ and 15‐year RC farming systems were significantly higher than RM system. Besides, soil quality declined with increasing soil depth. The SQI value, which may be used as an indicator to assess the soil quality of RC systems, was dominated by total nitrogen, which contributed 27.60% to the SQI value. On the whole, long‐term RC farming affected the soil quality of paddy fields through management methods including non‐rice season flooding, feeding, and no tillage. Through this study, it was found that MDS and SQI composed of appropriate physical, chemical, and biological indicators could more objectively analyze the soil quality of long‐term RC system and provide guidance for sustainable development of RC farming.

“…When the DO level in the surface water is less than 5 mg/L, it indicates a distressed environment to the aquatic lives such as fish [28]. It also indicates the appearance of sediment oxygen demand (SOD) caused by the algae in the water as well [29]. This value indicates an alarming sign as growth of aquaculture will be slow due to low exposure of dissolved oxygen.…”

Shah Alam is in Selangor, Malaysia and symbolized with several lakes that are popular among local communities and visitors for leisure and recreational activities. Among of these lakes, few lakes need management to look after its hygienic and well-being to serve its purpose as the recreational lake for the nearby community, such as Lake 7/1F, Shah Alam, Selangor. The secluded location of this water reservoir has made it unpopular, and improper management of it could invite an imbalance environment to its surrounding. Therefore, to initiate the effort, an Internet-of-Thing (IoT) water monitoring system is deployed at this lake to study the dissolved oxygen (DO) level in the water that could indicate the health status of this lake. The system consists of a DO sensor, embedded controller, self-charging power supply, wireless data transmission, and IoT dashboard for in-situ DO measurement. From the analysis, the lake has the normal cycle of DO production, but a dangerous condition is detected when the concentrated DO in the lake water is mostly below the saturation value.

“…The low dissolved oxygen concentrations in the water that affected the shrimp survival are related to the high oxygen demand in sediments (Dien et al . 2019a). In addition, those farmers who prefer to recruit wild postlarvae taking advantage of the inundation and water Exchange, eventually origin an accumulation of sediments in the ponds, causing a reduction of the culture área for rice, degradation of the ponds, and an extra additional cost for removing the accumulation of solids (Brennan et al .…”

Shrimp farming is one of the most important worldwide developed sectors; however, this development has induced a series of negative environmental impacts. One strategy to reduce these impacts is the integration or co‐culture of shrimp farming with agriculture. The integration of shrimp farming with commercial plants has been carried out with the objective of minimizing the environmental impact through the use of biosolids and effluents enriched with nutrients, taking advantage of available resources and generating greater income for producers. The aim of this review was to present the state of the art of integrated shrimp–vascular plant culture, focus on those plants with commercial interest and describe the different forms of integration. We reviewed over 158 studies dealing with integrated shrimp–plant cultures at different salinities, as well as the influence of salinity in the performance of both biological components. Plants suitable for the integration with shrimp farming are also examined, including advantages and disadvantages. Finally, several features that require further research are identified.
