Analysis of 4 sampling surveys on Jiangsu Shilianghe reservoir in May, July and October of 2011 and January of 2012, 109 species of algae belonging to 7 divisions were totally identified. The green algae and diatoms were the main species while Euglena and Cryptomonas were rare. The algal cell density in each season was compared as follows: summer (63.77 × 1000000 / L) > autumn (61.87 ×1000000 / L) > spring (43.31 ×1000000 / L) > winter (37.922 ×1000000 / L). Algae Shannon-Wiener index and Pielou indexes of each season were compared and described as follows: summer (2.71, 0.41) > winter (2.09, 0.32) > autumn (2.05, 0.31) > spring (1.85, 0.28). The Margalef indexes of each season were compared as follows: summer (1.51) > spring (1.38) > autumn (1.19) > winter (0.86). The water quality was assessed as α-medium pollution according to biological indicators. Sand mining, cages and obstruction between rivers and lakes may be the main reasons that lead to high algal cell density and low index of species diversity.

Abstract. Aquatic ecosystems and biota are often adversely affected by anthropogenic activities. Consequently, zooplanktons have been used to monitor anthropogenic impacts because of their sensitivity to their environment. Water quality and zooplankton community of the Eme River, Umuahia, was assessed between December 2017 and November 2018. The study was carried out in six stations in relation to human activities. Human activities in the watershed were dominated by sand mining. A quantitative filtration method was used for the zooplankton sample collection while standard sample collection and analytical methods were used for the water samples. The zooplankton species recorded were 27 while the most abundant zooplankton group was Rotifera. A known pollution indicator, Daphnia pulex, had the highest number of individuals. The effects of human activities in the watershed were reflected in the results of some of the physicochemical parameters of the river. The zooplankton assemblage and community structure also reflected the effects of human activities in the river. Combined effects of human activities and season contributed to the relatively low zooplankton abundance recorded particularly in some downstream stations. The impacts of sand mining on water quality and zooplankton were more remarkable in the downstream stations (4 6) where the activity was intense while a large number of children swimming and related activities during the dry season had some impacts in station 1. The dominance of indicator and tolerant species indicated that the river was undergoing eutrophication. Sand mining among other observed anthropogenic activities was a major contributor to the nutrient enrichment in the river. The major water quality parameters influencing the zooplankton community structure was revealed by canonical correspondence analysis.

The Impact

Aquatic ecosystems respond differently to diverse anthropogenic activities in their watersheds. Phytoplankton is sensitive to their environment and is used to monitor anthropogenic impacts. A study was carried out in a South-eastern Nigerian River between December 2017 and November 2018 in 6 stations; to assess the phytoplankton community, water quality, and anthropogenic impacts. Sand mining was a major activity in the river among others. The phytoplankton was sampled with the filtration method while water was collected and analyzed using standard methods. A total of 36 phytoplankton species were recorded with Chlorophyceae being the most abundant group. The most abundant species - Melosira granulata is a pollution indicator. The water quality and phytoplankton structure showed that the water was tending towards eutrophication. This is attributed to the observed anthropogenic activities and cumulative impacts of all the activities in the watershed. The impact of sand mining activities was observed more in the downstream stations (4 – 6) while perturbation from swimming children and related activities was observed in station 1. The community structure reflected the impacts of the activities while CCA showed the major water quality parameters that influenced the phytoplankton community structure.

This study uses the Islamic legal approach with qualitative research methods with techniques for collecting data through observation, interviews, and documentation. The research aims to reveal the commercialization of sand mining in Koto Kandis Village, Dendang District, East Tanjung Jabung Regency, and see how Islamic law views the sand mining activities carried out by the community in Koto Kandis. Based on the research carried out, the results are as follows: First, the process of commercializing sand mining is carried out by the Kandis City farmers using water and land lines. Second, this sand mining has positive impacts such as being able to increase economic income and help meet children's educational needs and deepen river water for smoother waterway trips. The negative impact of sand mining is road damage, air pollution due to dust, increased noise due to sand transport trucks, and a decrease in water quality due to sand mining. Third, in the view of Islam, natural resources in its essence belong to Allah's absolute mandated management, utilization and preservation to humans. In the management, exploration and exploitation of natural resources must pay attention to the preservation of nature and the environment and the sustainability of development. In the process of commercializing sand mining that occurs in Koto Kandis Village can be viewed from various aspects included in Islamic law including: Judging from the Word of Allah SWT in the Qur'an, Judging from the Word of the Prophet Muhammad, Judging from the Fatwa of the Indonesian Ulema Council (MUI) , Judging From the Istinbath Method of Islamic Law, Viewed From the Muhammadiyah Tarjih, Judging From the Principles of Fiqh.

Sand mining activities in Pasir Sakti District, East Lampung Regency, have changed the landscape and the allotment of land around it. The former sand mining area now becomes large puddles that are not utilized. This study aimed to analyze the suitability of water quality in ex-sand mining areas for tilapia (Oreochromis niloticus) culture. Observations were carried out at three stations in January-October 2019. Water quality measurements were performed to check water depth, clarity, temperature, current, dissolved oxygen, pH, salinity, nitrate, phosphate, iron, sulfate, and phytoplankton density. Analysis of suitability for aquaculture was carried out using weighting and scoring methods. Based on the results of the suitability analysis, the scoring result of the sand mining land for O.niloticus culture was in the range of 64% -68%. This score is classified as marginally suitable. The parameters with low scores are clarity, dissolved oxygen, temperature, pH, ammonia, phosphate, and iron (Fe) concentration parameters. Meanwhile, salinity, nitrate, sulfate, and phytoplankton density indicate conditions that are suitable for aquaculture. Therefore, severe treatment is needed to improve water quality to make it ideal for O.niloticus culture.
