The article presents the results of studying the hydrochemical regimes of carp ponds in polyculture and for the introduction of sterlet (Acipenser ruthenus) into polyculture. The highest pH values were in pond 2, and in the second half of June and the first half of July exceeded the upper limit of normal (norm 6.5–8.5) by 0.3 and 0.5, respectively. In July, the upper limit of the norm was exceeded in the water of pond 1, by 0.1 and 0.2, respectively. From August, the pH of water increased in both ponds until October and in pond 2 the active reaction of water was higher, compared to pond 1, 5.08.2020, by 18.3 %, 20.08.2020 by 12.3 %, 5.09.2020, by 3.8 %, 20.09.20 and 5.10.20, respectively by 2.5 and 2.4 %. Higher in pond 2, compared with pond 1, was the permanganate oxidation of water in all studied periods, but the largest difference was 5.07.2020 and amounted to 6.9 mg O/l. In the second half of July, permanganate oxidation of water was the lowest, but was at the upper limit of normal, then in August increased sharply and was highest in October – 26.3 mg O/l in the pond 1 and 26.5 mg O/l in the pond 2. Dichromatic oxidation of water of the studied ponds was during the experiment in pond 2 slightly higher than normal and ranged from 50.5 (5.06.2020) to 57.9 (5.07.2020) mg O/l and only 20.07.2020 it was the lowest and was 34.2 mg O/l. In pond 1, the dichromate oxidation of water at the beginning of the experiment was 52 mg O/l, gradually decreased and 20.06.2020, was 46 mg O/l, in July, the chemical oxygen demand (COD) increased sharply to 63.6 and also decreased sharply up to 40.5 mg O/l. From 05.08.2020, COD rose by 27.8 % above normal, remained at approximately the same level during September and decreased to 62 mg O/l in early October. The content of free ammonia in the water during the whole period of fish farming exceeded the norm from 2.6 to 5 times, and the highest, except for 20.06.2020, it was in pond 2. The highest difference in ammonia content in the water of the studied ponds was 5.07.2020 and 5.10.2020, and was, respectively, 0.1 and 0.08 mg N/l. The content of ammonium nitrogen and mineral phosphorus in the water of the studied ponds exceeded the norm, and the nitrogen content of nitrates and nitrites was within the norm. In pond water, the concentration of Ca2+, Mg2+, Na+, CO32-, HCO3-, SO42-, Cl-did not exceed the norm. was 5.07.2020, and was 1.20 mg/dm³, which is higher than the norm by 20 %. The total hardness and mineralization of water in the studied ponds did not exceed the norm.

Water Quality Indicators

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.

Monitoring of lakes and ponds water quality parameters is important to evaluate the interactions between quality and effects on aquatic organisms’ growth and health. Even if each water parameter individually may not be relevant, several parameters together can reveal dynamic processes that occur in the water. For instance, unbalanced pH values may increase ammonia and hydrogen sulfide toxicity. Nitrogen and phosphorus are associated with plant and algae growth, although phosphorus is generally the limiting nutrient in freshwater bodies. Accordingly, it is recommended to monitor and assess water quality parameters based on routine analyses. Therefore, the aim of this study was to generate an overview of our researches related to the monitoring of water quality collected from lakes and fish ponds. The parameters on the basis of which was evaluated the quality of water were: pH, electrical conductivity (EC), total hardness (TH), chemical oxygen demand (COD), nitrate-nitrogen (N-NO3-), nitrite nitrogen (N-NO2-), ammonium nitrogen (N-NH4+), phosphate phosphorus (P-PO43-).

The present work was conducted by monitoring the water from twelve major tin mine ponds water in Plateau State, North Central Nigeria (Bokkos, Barkin – Ladi and Jos – South) used for irrigation. Their quality was assessed in terms of physico-chemical parameters for dry and rainy seasons. The physico-chemical parameters such as; Turbidity, pH, Temperature, Electrical Conductivity (EC), Cation Exchange Capacity (CEC), Total Dissolved Solids (TDS), Total Suspended Solids (TSS), Total alkalinity (TA), Total Hardness (TH), Dissolved Oxygen (DO), Chemical Oxygen Demand (COD), Biological Oxygen Demand (BOD), Phosphate (PO43-), Sulphate (SO42-), Chloride (Cl- ), Fluoride (F-), Sodium (Na+) and Potassium (K+)  were investigated to ascertain the water quality for irrigation purposes. Water quality parameters with regards to its use for the purpose of irrigation such as FAO/WHO/FEPA standards satisfy the requirement for use in agriculture. However, turbidity which ranged from18.1 – 27.4 and 15.9 – 18.8, dissolved oxygen 20.9 – 26.3 and 20.2 – 27.4 mg/L, Total alkalinity 101 – 134 and 122 – 167mg/L, total phosphate 6.3 – 8.9 and 6.5 – 10.5 mg/L, BOD 7.4 – 23.8 and 7.2 – 29.2 mg/L, potassium 1.13 – 1.18 and 3.81 – 4.63 mg/L both in dry and rainy seasons, respectively were found to be above the irrigation water standard limits. The study therefore recommends that the mining pond water should be used with caution as some of the parameters are liable to be toxic to the irrigated crops. The positive correlation exhibited among some of the parameters examined is a clear indication of a common relationship between these sources of water.

The hydro geochemical features of Neyyar River for a period of one year from May 2015 to April 2016 were analyzed. Six sampling sites were fixed considering physiography and present landuse pattern of the river basin. The residents in the drainage basin are primarily responsible for framing a better landuse and thereby maintain a good water and sediment regime. Geospatial pattern of the present landuse of the study area indicated that the sustainability of this river ecosystem is in danger due to unscientific landuse practices, which is reflected in the river quality as well. The parameters such as hydrogen ion concentration, electrical conductivity, chloride, Biological Oxygen Demand, total hardness and sulphate of river water and Organic Carbon of river bed sediments were analyzed in this study. The overall analysis shows that the highland areas are characterized by better quality of water together with low organic carbon, which is mainly due to better landuse and minimal reclamation. The midland and lowland areas are characterized by poor quality of water with high organic carbon, which is due to high anthropogenic activities and maximum pollutants associated with the region together with the alteration in landuse from a traditional eco-friendly pattern to a severely polluted current pattern.

Sterlet Acipenser Ruthenus

DNA damage caused by exogenous or endogenous factors is a common challenge for developing fish embryos. DNA damage repair (DDR) pathways help organisms minimize adverse effects of DNA alterations. In terms of DNA repair mechanisms, sturgeons represent a particularly interesting model due to their exceptional genome plasticity. Sterlet (Acipenser ruthenus) is a relatively small species of sturgeon. The goal of this study was to assess the sensitivity of sterlet embryos to model genotoxicants (camptothecin, etoposide, and benzo[a]pyrene), and to assess DDR responses. We assessed the effects of genotoxicants on embryo survival, hatching rate, DNA fragmentation, gene expression, and phosphorylation of H2AX and ATM kinase. Exposure of sterlet embryos to 1 µM benzo[a]pyrene induced low levels of DNA damage accompanied by ATM phosphorylation and xpc gene expression. Conversely, 20 µM etoposide exposure induced DNA damage without activation of known DDR pathways. Effects of 10 nM camptothecin on embryo development were stage-specific, with early stages, before gastrulation, being most sensitive. Overall, this study provides foundational information for future investigation of sterlet DDR pathways.

This paper shows the results obtained in field analysis performed at the Tamis River, starting from the settlement Jasa Tomic - border between Serbia and Romania to Pancevo - confluence of Tamis into the Danube. The Tamis is a 359 km long river rising in the southern Carpathian Mountains. It flows through the Banat region and flows into the Danube near Pancevo. During the years the water quality of the river has severely deteriorated and badly affected the environment and the river ecosystem. In situ measurements enabled determination of physico-chemical parameters of water quality of the Tamis River on every 400 m of the watercourse, such as: water temperature, pH value, electrical conductivity, contents of dissolved oxygen and oxygen saturation. The main reason of higher pollution of Tamis is seen in connection to DTD hydro system. Sampling was performed at 7 points with regard to color, turbidity, total hardness, alkalinity, concentration of ammonium nitrogen, nitrite nitrogen, nitrate nitrogen, iron, chlorides and sulphates in samples. The aim of the present work was to evaluate water quality in the Tamis River taking into account significant pollution, which originates from settlements, industry and agriculture, and to suggest appropriate preventive measures to further pollution decreasing of the river's water.
