ABSTRACT: Aquaculture also known as fish farming is one of the methods for breeding rearing and harvesting of freshwater and marine species of fish and shellfish, in ponds, rivers, lakes and oceans. In this article an attempt has been put forth to study and apply techniques that could help in improving the water quality in aquaculture ponds and to further understand the role played by enzymes and probiotics by means of bio remedial procedures and protocols. Aquaculture productivity needs to be improved to cater the ever-increasing demand, no doubt, but simultaneously a proactive role for environment protection is required. The gathering of organic wastes worsens the water quality and reduces the level of dissolved oxygen in the fish aquaculture ponds. This further increases the formation of toxic metabolites such as ammonia (NH3), nitrite (NO2-) and hydrogen sulphide (H2S). Hence, NH4+ or NO3- removal processes (nitrification and denitrification) become essential for the pond water quality. This can be carried out by applying different types of nitrifying and denitrifying bacteria such as Nitrosomonas, Nitrobacter and Alcaligenes. In the present investigation, 2 earthen ponds were selected from Ponnagi near Eluru in Krishna district, Andhra Pradesh, India. One pond (Pond A) was treated with probiotics having Nitrosomonas, Nitrobacter and Alcaligenes sps. And the other pond (Pond B) was kept as control. During the culture period, the water samples were collected from probiotics treated and control ponds for analysis of water quality parameters. The current study is aimed to focus on the changes in water quality and biochemical characterization of bacterial isolates from water samples of Ponnagi area in probiotic treated ponds and to compare the results with ponds not treated with probiotics.

A study was conducted to evaluate the water quality parameters of pond water at Mymensingh Urban region. The water samples were collected from 30 ponds located at Mymensingh Urban Region during August to October 2010. The chemical analyses of water samples included pH, EC, Na, K, Ca, S, Mn and As were done by standard methods. The chemical properties in pond water were found pH 6.68 to 7.14, EC 227 to 700 ?Scm-1, Na 15.57 to 36.00 ppm, K 3.83 to 16.16 ppm, Ca 2.01 to 7.29 ppm, S 1.61 to 4.67 ppm, Mn 0.33 to 0.684 ppm and As 0.0011 to 0.0059 ppm. The pH values of water samples revealed that water samples were acidic to slightly alkaline in nature. The EC value revealed that water samples were medium salinity except one sample and also good for irrigation. According to drinking water standard Mn toxicity was detected in pond water. Considering Na, Ca and S ions pond water was safe for irrigation and aquaculture. In case of K ion, all the samples were suitable for irrigation but unsuitable for aquaculture.J. Environ.

AbstractIntensification of fish farming practices is being driven by the demand for increased food production to support a rapidly growing global human population, particularly in lower-middle income countries. Intensification of production, however, increases the risk of disease outbreaks and thus likelihood for crop losses. The microbial communities that colonise the skin mucosal surface of fish are poorly understood, but are important in maintaining fish health and resistance against disease. This skin microbial community is susceptible to disruption through stressors associated with transport, handling and the environment of intensive practices, and this risks the propagation of disease-causing pathogens. In this study, we characterised the microbial assemblages found on tilapia skin — the most widely farmed finfish globally — and in the surrounding water of seven earthen aquaculture ponds from two pond systems in distinct geographic regions in Malawi. Metabarcoding approaches were used to sequence the prokaryotic and microeukaryotic communities. We found 92% of prokaryotic amplicon sequence variants were common to both skin and water samples. Differentially enriched and core taxa, however, differed between the skin and water samples. In tilapia skin, Cetobacterium, Paucibacter, Pseudomonas and Comamonadaceae were enriched, whereas, the cyanobacteria Cyanobium, Microcystis and/or Synechocystis, and the diatom Cyclotella, were most prevalent in pond water. Ponds that clustered together according to their water prokaryotic communities also had similar microeukaryotic communities indicating strong environmental influences on prokaryotic and microeukaryotic community structures. While strong site-specific clustering was observed in pond water, the grouping of tilapia skin prokaryotes by pond site was less distinct, suggesting fish microbiota have a greater buffering capacity against environmental influences. The characterised diversity, structure and variance of microbial communities associated with tilapia culture in Malawi provides the baseline for studies on how future intensification practices may lead to microbial dysbiosis and disease onset.HighlightsTilapia skin communities vary in different ponds but share some common taxaPond sites have a stronger influence on water microbiome community structure than in fish skinSelected skin-associated taxa could be used to monitor dysbiotic eventsThe fish skin microeukaryotic community is complex and poorly characterised

The growth and development of fish depend on the physicochemical properties of water, such as temperature, turbidity, concentration of hydrogen ions (pH), dissolved oxygen, total alkalinity, total hardness, nitrates, nitrites, etc. The article presents data on the hydrochemical regime of growing ponds of the farm “Rudnyky” of Lviv region. Studies have shown that the water quality indicators of growing ponds during the growing season are within the normative values and the water is suitable for fish farming. In the breeding ponds of the Rudnyky fishery, the water quality indicators fluctuated within the following limits, namely: the hydrogen index (pH) was within the maximum permissible concentrations (6.7–8.0). The content of dissolved oxygen in the water during the growing season was within normal limits (6.5 to 7.8 mg/l) and fully met the requirements for carp fish ponds, the alkalinity of the water was average and varied between 2.40 and 3.20 mg-eq/l, permanganate and dichromate oxidation varied slightly – 8.6–15.45 mgO/l and 25.6–40.50 mgO/l, which corresponds to the normative indicators for fish farming. The concentration of ammonium nitrogen (NH4+) in the growing ponds of the farm averaged 0.008–0,520 mg N/l, the content of nitrites and nitrates was 0.002–0.100 mg N/l and 0.060–0,520 mg N/l, respectively. The average concentration ranged from 0.10 mg P/l to 0.40 mg P/l of mineral phosphorus (PO4-3), which did not exceed the normative values. The amount of total iron in the water of the pond did not have high values, averaged 0.10–0.38 mg Fe/l, which was within the maximum allowable concentrations. The values of total hardness of water were determined as moderately hard and were in the range of 2.9–5.0 mg-eq/l. The salt composition of pond water was characterized by total mineralization, the ratio of ions and the content of chlorides, sulfates, bicarbonates. During the study period, the content of chlorides (Cl-) sulfates (SO4 2-); hydrocarbons (HCO3-), did not exceed the maximum allowable concentration. Among the cations in the pond water, calcium ions (Ca2+ ) predominated, their content averaged 28.2–80 mg Ca/l. In the studied pond, the concentration of magnesium (Mg2+) reached average values – 6.8–20.0 mg/l. The total mineralization of water was 300.4–440.4 mg/l. By the nature of the ionic composition, the water of the growing ponds belongs to the hydrocarbonate composition of the calcium group.

Taman Nasional Sembilang merupakan salah satu taman nasional yang terletak di Sumatera Selatan dan menjadi kawasan mangrove terbesar di barat Indonesia. Sebagian besar wilayah mangrovenya telah mengalami alih fungsi menjadi tambak pasang surut. Hal ini menyebabkan timbulnya kekhawatiran kerusakan mangrove di taman nasional. Salah satu upaya untuk mempertahankan wilayah mangrove adalah dengan melakukan sistem silvofishery, yaitu penanaman mangrove dan budidaya bandeng dilakukan secara bersamaan di tambak. Penelitian ini bertujuan untuk menganalisis kualitas air dan kondisi nutrien di tambak di daerah restorasi silvofishery di Taman Nasional Sembilang. Penelitian dilakukan dengan metode purposive sampling di tambak silvofishery, tambak non-silvofishery, dan badan air sungai di seluruh wilayah taman nasional. Pengukuran dilakukan terhadap parameter kualitas air dan kandungan nutrien khususnya nitrat dan fosfat. Hasil penelitian menunjukkan bahwa kehadiran tanaman mangrove di daerah tambak mampu memperbaiki kandungan oksigen dan pH air tambak. Mangrove juga menunjukkan kemampuan dalam mengikat nitrat yang secara tidak langsung akan mencegah air tambak dari polusi. Namun, kandungan fosfat tinggi menunjukkan bahwa tanaman mangrove muda di wilayah restorasi belum mampu mengikat nutrien ini secara signifikan. Hasil penelitian ini menunjukkan bahwa hutan mangrove sangat bermanfaat bagi kegiatan budidaya tambak karena kemampuannya dalam menyerap polutan nutrient. Kata kunci: silvofishery; kolam; nitrat; fosfat; Taman Nasional Sembilang Sembilang National Park is one of the national parks which is located in South Sumatera and became the largest mangrove area in western Indonesia. Most of the mangroves area in this national park has been experiencing conversion to be tidal ponds. This has resulted in concerns on mangrove forest destruction in the park. One of the efforts to maintain mangroves area is by applying silvofishery system, which is mangrove planting and cultivation of milkfish in ponds performed simultaneously. This study aims to investigate the water quality and nutrient condition in the ponds in the area of silvofishery restoration at Sembilang National Park. The study was conducted by purposive sampling method in the silvofishery ponds, non-silvofishery ponds, and river water bodies throughout the park. Measurements conducted on water quality parameters and nutrient content, especially nitrate and phosphate. The results showed that the presence of mangrove in the ponds area is able to improve the oxygen content and pH of pond water. Mangroves also demonstrated the ability to bind nitrates which indirectly will prevent the pond water from pollution. However, the high phosphorus content showed that young mangrove plants in the restoration area have not been able to significantly bind the of this nutrient. The results of this study showed that mangrove forests are very beneficial for aquaculture activities because of its ability to absorb nutrient pollutants.

This study was conducted to know the status of physicochemical water quality parameter and heavy metal concentration in the water of Buriganga river, adjoining to Dhaka city. Water samples were collected from five different points of Buriganga river and were analyzed to determine pH, electrical conductivity (EC), total dissolved solids (TDS), dissolved oxygen (DO), biological oxygen demand (BOD), chromium (Cr), lead (Pb), cadmium (Cd), copper (Cu) and manganese (Mn) content. Most of the measured water quality parameters and concentration of heavy metals were exceeded the standard level set by ECR and ADB. Among heavy metals concentration, level of chromium and cadmium were 4-5 times higher than the standard drinking level, these results indicate that surrounding industrial wastewater discharging from textile and tannery industries, which pollute the Buriganga river water. During the observation, at Hazaribagh station BOD level was found 32 times higher than drinking water standard level and 6 times higher than standard irrigation level, indicating Buriganga river water is extremely polluted by microorganism and is not suitable for household and irrigational use. Similarly, DO level at Buriganga river water was 5 times lower than the standard level, which indicates that Buriganga river water is extremely polluted and is unsuitable for aquatic life which are dependent on DO for their sustain. In the present study, the measured level of EC, chromium, cadmium and copper were found higher level as compare to the previous studies.J. Environ. Sci. & Natural Resources, 9(2): 97-104 2016

The issues of freshwater pollutions and the high demand of clean freshwater for daily human activities have forced developing countries such as Malaysia to continuously monitor the quality of the freshwater. The present study objective is to present the trend of water quality status in the Kelantan River downstream, Peninsular Malaysia from 2005 to 2018. Water samples were collected during dry and monsoon seasons from a sampling station located at downstream of the Kelantan River. Water quality parameters such as temperature, pH and dissolved oxygen (DO) were measured in situ while other parameters were analysed in the laboratory based on retrieved water samples. Water quality status was determined based on National Water Quality Standard (NWQS) for River in Malaysia by calculating the water quality index (WQI) according to the concentration of six water quality parameters involving pH, dissolved oxygen (DO), biochemical oxygen demand (BOD), chemical oxygen demand (COD), suspended solids (TSS) and Ammonia Nitrogen (AN). The results showed that Kelantan River had good water quality during the dry season classified in Class II at 2005. The water quality was found to be slightly lower during the monsoon season in year 2006. In addition, increasing the number of construction, human activities in the land use areas, land use changes and the sewage water from domestic, industrial, wet market and food outlets in the Kelantan State have declined the water quality in Kelantan River from Class II (in 2005) to Class III (in 2010 and 2011) and to become Class IV in 2017 to 2018. The results of the present study are expected to give valuable information for the water managers in order to deal with better strategies in controlling the quality of freshwater at the Kelantan River and minimize the incidence of pollution-oriented problems, thus the water can be utilized for various water uses with appropriate quality.
