“…Yuan et al reported higher paddy rice yields [28], while Abdelraouf and Ragab reported a yield increase in wheat [29] from using fishpond water compared to freshwater, which was associated with increases in nitrogen and phosphorus and was also confirmed by this study (Tables 3 and 4). Recall that both ditchwater-and fishpond-water-irrigated fields receive compost and manure from the geese on the farm.…”

“…The study results reveal that watering with fishpond water for almost two decades has positively affected grape yields compared to irrigating with just ditchwater (Figure 2), which is consistent with similar studies from other locations and systems. In different studies, fishpond water increased paddy rice [21,22,28] and wheat [29] yields. The positive yield effects from fishponds relate to soil fertility and health improvements, as observed by others [28,29], which is also consistent with the findings of this study.…”

Climate variabilities continue to hinder sustainable food production with an increasing need to use resources such as water and soil efficiently. The quest for these efficiencies in agriculture systems drives innovations among farmers. However, limited data on farm practices, such as irrigating with fishpond water and their effects on soil health, hinder their adoption as climate-smart innovations. In a nearly twenty-year-old vineyard with two distinct irrigation practices (irrigation with recycled fishpond water and irrigation with ditch water), this study was carried out as an exploratory study to investigate the influence of recycling fishpond water on soil health parameters and yield. Soil samples were taken from two different irrigation fields in summer and winter for lab analysis on soil health parameters (organic matter and carbon, nitrogen, phosphorus, microbial biomass, and microbial respiration). Averages over the two seasons of field measurements indicate that long-term irrigation using recycling fishpond water increased the measured soil health parameters (organic matter (13%), organic carbon (30%), nitrogen (17%), phosphorus (46%), microbial biomass (18%), and microbial respiration (56%)) in both summer and winter months when compared to fields receiving just ditchwater irrigation. Using water in a way that can improve soil health increases biodiversity and improves the efficiency of our limited water resources in semi-arid agricultural lands, and this strategy is a climate-smart tool that can help reduce water risks in dry agricultural regions such as Arizona.

“…On the other hand, aquatic animals only absorb one-third of the nitrogen present in their feed [ 3 , 21 , 22 ]. The remaining unabsorbed nitrogen is retained in aquaculture wastewater and sediment [ 23 ], which is subsequently discharged into the river to cause environmental pollution together with the aquaculture wastewater.…”

“…Li [24] found that it can nevertheless fulfill the nutrient requirements of rice when used in aquaculture wastewater, under 80% of nitrogen conventional fertilizer. Meanwhile, Zhou [22] and Yan [3] discovered that 80% of the standard fertilization treatment resulted in comparable yield levels to traditional fertilization, and the yield was still above 9000 kg/hm 2 , without the potential risk of reduced yield. Therefore, the irrigation of paddy fields with aquaculture wastewater could satisfy the demand for rice of water and nutrients, reduce the use of water and fertilizing amount, which means it has important economic benefits.…”

Irrigating aquaculture wastewater in appropriate irrigation and drainage modes in paddy fields could reduce water and fertilizer loss. However, the precise mechanisms involved in the degradation and movement of nitrogen in various water and fertilizer modes are still not fully understood. This study involves conducting a controlled experiment using barrels to examine the effects of various water quality, irrigation and drainage methods, and fertilization levels. The aim is to analyze the patterns of nitrogen degradation, loss, migration, and absorption in surface water, underground drainage, and soil leakage at different depths. The results showed the following: (1) The paddy field has a significant purification effect on aquaculture wastewater after one day of irrigation, reached at 78.55–96.06%. (2) Aquaculture wastewater irrigation increased nitrogen concentration in the plough layer, which helps rice roots absorb nitrogen and boosts plant TN. (3) In special dry years, underground seepage is the predominant method of nitrogen loss, and underground drainage nitrogen concentration peaks 2–6 days after fertilization. (4) Under aquaculture wastewater irrigation, the TN loss load of II decreased by 27.65–42.45% than FSI. Compared with IA-80, the TN degradation rate of IA in surface water increased by 18.51%, TN loss load decreased by 5.48%, TN absorption rate significantly increased by 14.61%, and yield increased by 31.14% significantly. IA is recommended in special dry years, which can improve the TN absorption rate and ensure high yield while significantly reducing the loss load of nitrogen. The findings can provide a basis for the purification of aquaculture wastewater through paddy field ecosystems in response to fertilizer supply levels.

In recent years, due to water pollution water quality in Jingzhou City has been deteriorating and does not come up to the national standard of drinking water. Incompetent water over the district leads to scarcity of potable water, especially in the rural area more than 60% of the total population has a low reliability in drinking water security. For solving this problem some useful strategies should be taken, including: a) environmental supervision at Jingzhou section of Yangtze River; b) prevention and control of water pollution where has been or will take place in rivers and lakes within the district; c) financial and technological support on rural drinking water project and rural environmental protection; and d) establishment of central water supply construction in the rural area.
