One of the main reasons for the decline in fish numbers is the insufficient quality of water used in hatcheries. The degree of purification of recycled water does not meet the requirements for water in pools. Thus, in order to reduce pollution concentrations, it is necessary to develop new technologies for the treatment of recycled water from fish farming plants, including through the integration of a lighting and aeration plant into them, as well as a sorption unit using agricultural waste, namely rice straw

The article is devoted to the development of new professional standards aimed at improving the quality of vocational education. A new generation of standards professional education will develop and innovative educational programs. Uniform requirements to professional activity help to maintain the uniform quality of labour in all enterprises of the industry, conduct training needs and improving qualification of personnel and certification of personnel, to develop modular training programmes to introduce new technologies of training based on competencies, to conduct an independent assessment of learning outcomes, to create the new classifier of professions, and to form a coherent system of continuous professional education. Currently, due to the importance of activity of the enterprises of sphere of services to solve the problem of improving the quality of life of the population, Russia has adopted and is implementing various Federal programs, such as Federal target program «Development of domestic and outbound tourism in the Russian Federation for 2011–2018», «bases of state policy in the field of healthy nutrition of the population for the period till 2020», «Strategy of development of physical culture and sports in the Russian Federation for the period till 2020» and other documents. The experience of socio- economic development of leading countries shows that the transition to a qualitatively new level of economy associated with the intensive mobilization of sources of growth, especially with the growing importance of using highly qualified personnel and the introduction of the evaluation system of vocational qualifications. Currently there are many forms of support for professional level performers of services. A key instrument for the formation of professional requirements to the specialists, workers, artists, etc. are of professional standards. Developing market processes in the field of services for the modeling and design of apparel, fur, leather, knitwear for in- dividual orders and the impact of professional community allow us to state that due to competition the quality of services increases significantly, and a key criterion in assessing the quality is the qualification of executors. Foreign and domestic experience shows that in the current conditions of socioeconomic development, develop- ment of professional standards «Specialist in modeling and designing sewing, fur, leather, knitwear for individual orders» becomes extremely important. The development of professional standards will take into account the spe- cifics of the actual services for the modeling and design of apparel, fur, leather, knitwear for individual orders to reflect the contemporary activities of a specialist in the field of fashion and beauty. The professional standard will be fully and clearly describe the requirements for specialists, to give an indication of the set of normative documents, regulating this activity.

Now a day’s water pollution became a national and global issue not only in India but over the whole world. Like India other countries are also facing the same problem of water pollution due to agricultural waste, industrial waste, sewage waste and so on. In this paper it has been explained clearly with the help of considerable number of references. It gives the information about the pollutants which pollutes the water. Sensors have a ability to Control and monitor the quality of water as well as able to detect the contaminants added due to human generating activities. Sensors can be used for the selection and identification of the techniques which will be suitable for performing the given task that is identification of pollutants present in water. Various pollutants found in water are pesticides, harmful chemicals, heavy metals, nutrients, etc. We will also going to discuss about the different techniques used for water pollution detections.

The clean water service of PDAM Loa Janan Sub-district has not yet reached all villages, including Batuah Village, which has not yet received clean water services from the government. To meet the need for clean water for the people of Batuah Village, they use drilled well water, dug water that does not meet health standards because it contains heavy metals that are toxic (poisonous). This activity aims to meet the needs of clean water for the community in Batuah Village. Activities start from identifying the potential and quality of raw water sources which include physical, chemical and biological parameters, designing and manufacturing clean water treatment units as well as testing the quality of water products produced, socialization and training to partner groups on the process of operating clean water treatment technology and monitoring the sustainability of the water treatment process after being managed independently by the partner group.

Florida water-resource professionals deciding whether to implement a costly water protection program or to invest in better tap water treatment technology may wonder: Are such investments justified? What are the benefits of the program or investment decision? Just how highly do Floridians value their water? This 5-page fact sheet written by Tatiana Borisova, Syed Irfan Ali Shah, Tara Wade, Xiang Bi, and Kelly Grogan and published by the UF/IFAS Food and Resource Economics Department reviews studies that help assess the value Floridians assign to maintaining or improving the quality of the water supply. http://edis.ifas.ufl.edu/fe1059

The success of a culture depends on the quantity and quality of water used in fish culture without water exchange, the concentration of aquaculture waste such as ammonia (NH3) will increase very rapidly and is toxic to the cultivated organism. One of the innovations applied in fish farming is integrating plants through an aquaponics system. This study aims to determine the effect of using a settling tub in reducing ammonia waste (NH3) and growth in tilapia aquaculture using an aquaponic tidal system. The size of the initial tilapia seeds used is 3-4 cm. There are two treatments used, without settling tub (A) and addition of settling tub (B) with three replications. However, the results showed no significant differences (P>0.05) between treatments for all parameters observed. It is necessary to carry out further research on different fish and plants to see the optimization in reducing ammonia waste (NH3).

The southern slopes of the Alps are facing a changing climate. This is acutely perceived in areas ideally suited to highquality agriculture, such as the Val di Non, in the northern Italian Province of Trento. Here agriculture has been constantly improving in technology and management. Drip irrigation now covers 100% of fruit tree cultivation, notably apple and cherry representing 90% of the over 8,000 hectares of farmed land.Cooperative management of resources, both in irrigation and land management, underpins and strengthens the agricultural sector in the Province of Trento. The Province's primary legislative control over agriculture and environmental protection maximizes the legislator's closeness to the interests and needs of agricultural producers and economic actors. This article illustrates the norms regulating agriculture and environmental protection in the Province of Trento. Secondly, it presents the ongoing complex research aimed at striking a new balance between environmental concerns (namely, the preservation of the quality of water streams in Val di Non) and growing demand for water for local agricultural production. The needto provide adequate water supply for agriculture conflicts with the necessity to guarantee minimum flow levels in local water streams, as provided for by law (environmental flow), as well as to preserve adequate quality of flowing water. The article proposes to connect existing irrigation infrastructure – irrigation networks, reservoirs and pumping stations. Itanalyzesa range of issues – parasite management; insurance against spring frost; labor protection; processing and marketing of produce. It connects with local research centers – the University of Trento for climatological research, the Mach Foundation for agronomic research and the Kessler Foundation for the application of new technologies to data harvesting and management.

Fish farming activities in recent years, many shows water quality conditions do not support fish life are maintained optimally and decreases the carrying capacity, one DO and pH parameters. As a remedial action is carried out either by probiotic bacteria One commonly used in the application of probiotics is Lactobacillus spp. Gram positive bacterium Lactobacillus spp. widely used as probiotics to improve the quality of air Penggunaan Lactobacillus spp. is expected to improve the quality of water that is accelerating the overhaul of organic material in the water and suppress harmful microorganisms that can affect the dynamics of DO, pH and increasing nutrient waters. Barley straw is a powdered extract of hay-producing H2O2 which serves to inhibit the growth of microalgae. The use of straw extract powder has become more common as an alternative method for controlling excessive algae growth by blocking and not get rid of it so that stabilization of the abundance of plankton in the water can be controlled well.To study the role of Lactobacillus spp. and barley straw in the management of organic matter and plankton abundance Giving a research study Lactobacillus spp. and barley straw to the dynamics of DO, pH and Abundance of Plankton.

Abstract A sample of 1,114 households in three countries located in the Limpopo River Basin was surveyed to investigate willingness to use (WTU) and willingness to pay (WTP) for different quality attributes of recycled water. The results indicate that 36% of the households are willing to use recycled water for potable uses and only 70% are willing to use it for non-potable use such as gardening. WTU recycled water was found to be associated with gender, age, education, occupation and perception of quality of water from the main source. Households are willing to pay 76% of the price of standard water for improved quality in recycled water with no colour.
