Temperature is one of the most dominant water quality parameters on the survival of fish, and almost every living organism has the optimum temperature for its life. One of the obstacles in the cultivation activity is the high level of death in the most critical phase of the larvae so that the handling and carrying capacity of optimal environmental conditions can minimize the death of the larvae as well as the extreme temperature changes will also cause higher death rates of larvae. In the maintenance effort, the quality and quantity of the resulting larva becomes an important factor, as the success of production support to reach the next phase. Therefore, to find out the larval synthesis is done research about the optimum temperature with treatment temperature 240C, 260C, 280C and 300C to the survival of maintenance of botia larvae (Chromobotia macrachantus). The water quality parameters of CO2, NH3, DO, and pH are carried out at the beginning and end of the study for 28 days. The results showed that the highest survival rate at temperature treatment 240C and 260C with a value of 100%.Keywords : Botia Larvae, Temperature, Survival Rate AbstrakSuhu merupakan salah satu parameter kualitas air yang sangat dominan terhadap kelangsungan hidup ikan, dan hampir setiap organisme yang hidup didalamnya memiliki suhu optimum untuk kehidupannya. Salah satu kendala dalam kegiatan budidaya adalah tingginya tingkat kematian pada fase paling kritis yaitu larva sehingga penanganan dan daya dukung kondisi lingkungan yang optimal dapat meminimalisir kematian larva demikian pula dengan perubahan suhu yang ekstrim juga akan menyebabkan tingkat kematian larva semakin tinggi.

This trial aimed to evaluate effects of stocking densities of 1-5 fish/m2 on growth performance, survival rate and economic efficiency of Asian seabass (Lates calcarifer) in earthen ponds. Fish with an initial length of 90.7 ± 0.1 mm and weight of 20.8 ± 0.1 g/fish and ponds with 600 m2 each and 1.5 m depth were used for this study. Experiment was designed with three treatments, including different stocking densities of 1, 3 and 5 fish/m2. The fish was fed with pellete feed containing 43 - 44% crude protein. Water quality parameters including temperature, dissolved oxygen, pH, salinity, transparency and ammonia concentration were measured once a week. Fish were sampled every 30-day intervals for length and weight measurement then for their growth estimation. Costs were recorded for economic efficiency estimation. Results showed that the water quality parameters were in suitable ranges for growth and development of Asian seabass. The final average length and weight of density 1 fish/m2 was significantly higher than those at 3 and 5 fish/m2 (P < 0.05). However, there was no significant difference on the fish growth in terms of daily length and weight gain, as well as survival rate and feed conversion ratio between different stocking densities. Asian seabass culture at 3 and 5 fish/m2 resulted in a higher profit compared to at 1 fish/m2. The highest economic efficiency in terms of area pond was showed at 5 fish/m2 treatment.

The aim of present investigation was to analyze the variations in the physio-chemical properties of the ground water of Cuttack district Odisha. In the present study 98 samples were collected and analyzed to assess the quality of ground water. The pH, electrical conductivity (EC), total hardness and total alkalinity of the collected 98 samples were in the range of 4.6-7.3, 36-4550 μS/cm, 40-200 mgl-1, 20-680 mgl-1 respectively. Similarly, the other important water quality parameters such as; chloride, nitrate sulphate and phosphate concentration were varies between BDL-327, 1.8-86.25, BDL-194 and BDL to 3.2 mgl-1 respectively. The pH of the alluvial groundwater is controlled by the HCO3. The fluoride concentration was varies from BDL to 2.38 mgl-1. Apart from few samples, 90.81% fluoride contaminated samples comes under the category of quality group A (< 1 mgl-1flouride). Similarly, out of total samples collected only in three samples the uranium concentration estimated to be more than 5ppb. Among the water quality parameters there exist a positive correlation between pH and fluoride with a correlation coefficient of 0.641. From the correlation analysis it is found that, higher concentration of fluorid correlated with higher pH. Similarly the correlation coefficient between calcium and chloride is very high i.e. 0.500, which strongly supported the existence of calcium in the study area is predominantly in the form of CaCl2. Most of the ground water samples meet the requirements of the WHO drinking water standards with respect to salinity, main constituents and potentially toxic trace elements such as uranium

Two water effluents that drain from the abandoned coal mine of São Pedro da Cova (NW Portugal) were characterized in terms of their physic-chemical properties and suitability for irrigation purposes. Samples were also collected in a local surface stream, upstream and downstream from the mine drainage points, also used for irrigation by local farmers. Water samples were analyzed for major and minor ions and for trace element concentrations. Sampling campaigns started in 2017 and ended in 2019 and there were 46 water quality parameters tested. There were also proposed all-inclusive indices (the Water Quality Index and the Contamination Index, and also the Trace Element Toxicity Index) based on specific groups of 18 and 17 physic-chemical parameters, respectively, to achieve adequate monitoring requirements for mine effluents and surface water from coalfield. From the physical and chemical aspects of mine water it is inferred that the mine is not producing acid mine drainage. The coal mine water is of medium to high salinity, having almost neutral pH and a high thermal stability during the year, which is a distinguishing feature of the effluents. When compared to international irrigation water quality standards, as Food and Agriculture Organization of the United Nations admissible concentrations, the impacted waters are unsuitable for irrigation. The major outliers to the guidelines were iron, manganese, potassium, magnesium and bicarbonates, being also detected carcinogenic polycyclic aromatic hydrocarbons. Cost-effective ways of monitoring water quality parameters are needed to help control and manage the impact of coal mine effluents that should be treated before releasing into a ditch system that could be then used by local farmers to irrigate their crops.
