The article presents the results of the researches conducted on Lake Ozgent (the Kyzylorda region). The data on hydrochemical regime of the lake, ionic composition, composition of biogenous compounds, oxygen and thermal regimes were collected and analysed. There has been done the assessment of food supply and current state of the ichthyofauna. According to the obtained data, the recommendations about using Lake Ozgent were made, the recommended meliorative events (meliorative fishing, repair of hydroconstructions) were held and stocking the fishing material of carp was carried out. Based on the work results it has been established that in the conditions of Lake Ozgent the pure gain in 5 months of cultivation (on extensive technology when using only the natural food supply) made 385.6 g in a carp, 301.4 g in a white silver carp and 428.7 g in a grass carp. In the full catch of commodity fish species, the overall fish productivity of Lake Ozgent will make 101.9 kg/hectare, of them carp will take 43.4 kg/hectare, grass carp - 13.5 kg/hectare and white silver carp - 45 kg/hectare. The growth of the grown-up fish in Lake Ozgent corresponds to biotechnical standards of fish cultivation in the in polyculture of the feeding lakes.

It is shown that the leading role in the aquaculture of Iraq belongs to Cyprinids, which account for over 80 % of all fish farming production. The most widespread in the country are four main world species of carp aquaculture: common carp (Cyprinus carpio), grass carp (Ctenopharyngodon idella), silver carp (Hypophthalmichthys molitrix) and bighead carp (Aristichthys nobilis). Basically, the traditional technology of growing Cyprinids in ponds is used, which includes the main fish farming processes: care of broodstock to prepare them for spawning, collecting eggs and milt, eggs fertilization and incubation of embryos, raising juveniles and marketable fish. Currently, there are about 2 thousand private fish farms, which have ponds of various sizes from 4 to 100 hectares. Cultivation of Cyprinids in Iraq is carried out mainly by extensive methods: the use of the natural food base of reservoirs with low fish stocking density in polyculture. The fish productivity of ponds varies greatly in different fish farms from 1,5 to 6 t/ha, which is due to economic reasons. The data on changes in the temperature of pond water during the year and hydrochemical indicators are given, which shows favorable conditions for Cyprinids rearing. Information on the use of compound feeds for growing carp in ponds is provided, and data on the composition and nutritional value of the feed used. The fish culture indicators for the main biotechnical processes of the rearing of four Cyprinid species in Iraq are described in detail. In the conclusion, it is indicated that for the effective development of aquaculture in Iraq, government support is needed in the form of a developed long-term program and legislative acts.

Objective of research: to present the actuality and novelty of application of fish and grass “rotation” because this allows to reveal new data on pond drainage planning which is the most effective in sanitation of the fish farm. Materials and methods: to determine the most effective cycle for the summer drying of ponds, we studied ecological and epizootological features of fishing ponds, which had been used after drying within 1 and 5 years. As research object served 8 fish ponds: 4 drained ponds under crop (40 ha), 4 — overflowed (40 ha) and filled with one-year carps (2,5-З thousand ind./ha) and silver carps (1,2-1,4 thousand ind./ha). Results and discussion: The results of comparative research on anti-epizootic efficacy of pond drying at different periodicity of 1 and 5 years with the use of fish and grass “rotation” are provided. Data on decreased invasion of fishes (carp, silver carp) by parasites, absence of causative agents of infection, improved blood indicators, increased fish production at annual pond drying (with the use of fish and grass “rotation”) compared with the pond drying of 5 year periodicity are presented. Advantages of economic efficacy of the annual frequency of pond drying are confirmed: twice increased commercial fish production; reduced expenses for purchase of food (own barley and wheat production), drugs, disinfectants, fertilizers that allow increasing economic revenue and making profit.

<em>Abstract</em>.—Numerous natural resource agency and media reports have alleged that Asian carps were introduced into the wild through escapes from commercial fish farms. This chapter traces the chronology associated with importations of Asian carps to North America and discusses the likeliest pathways of their introduction to the wild. The U.S. Fish and Wildlife Service first imported an Asian carp species, grass carp <em>Ctenopharyngodon idella</em>, in 1963. Since then, state and federal agencies, universities, and private fish farmers have interacted to import Asian carps, to develop production technologies, and to promote their use in both public and private sectors in a number of different states. These importations and stocking, whether in confinement or, in the case of the grass carp, sometimes in open waters, were purposeful and legal. Asian carps were introduced to take advantage of their unique food preferences (planktivory by silver carp <em>Hypophthalmichthys molitrix </em>and bighead carp <em>H. nobilis</em>, herbivory by grass carp, and molluscivory by black carp <em>Mylopharyngodon piceus</em>). The first known accidental release of diploid grass carp was in 1966 by the U.S. Fish and Wildlife Service in Stuttgart, Arkansas. Other early reports of grass carp in the wild were from waters in Alabama, Georgia, and Florida. Grass carp were reported from the wild in 1970, 2 years before the first private hatchery received grass carp. By 1972, grass carp had been stocked in open water systems in 16 different states. Silver carp and bighead carp were first imported purposely by a commercial fish producer in Arkansas in 1973. All silver and bighead carps were transferred to the Arkansas Game and Fish Commission by March 1974 where they first successfully spawned silver carp and bighead carp later that year. The first report of silver carp in the wild was in Arizona in 1972, although strong evidence suggests that this may have been a misidentification, followed by reports in Arkansas in the wild in 1975. The Arkansas report occurred 2 years before bighead carp and silver carp were returned to private hatcheries for commercial production. By 1977, silver carp and bighead carp had been introduced to Alabama, Arizona, Arkansas, Illinois, and Tennessee. Research and stockings of silver carp and bighead carp were conducted by at least six state and federal agencies and three universities in seven states in the 1970s and 1980s. Public-sector agencies, which were successful in encouraging development and use of Asian carps that today are in commercial trade, are the likeliest pathways for the earliest escapes of grass carp, silver carp, and bighead carp.

Pond fisheries are one of the promising areas of fisheries in Ukraine and the world. The vast resources of the inland waters of our country are a reliable source of valuable fishery products. However, the potential of this source is not fully exhausted. Therefore, a significant increase in the production of commercial fish can be achieved as a result of the construction of new commercial fisheries and factories, whose task is to recreate fish stocks. One of the leading places among all kinds of outdoor activities is sports and amateur fishing. Capture fishing has become a permanent fixture for hundreds of millions of people around the world. It is estimated that in Ukraine sport and recreational fisheries cover about 10 % of the population. The purpose of the work was to find out the current state of fish productivity of the Black Sea ponds of Odesa region for the creation of specialized fisheries. The fish productivity of the Black Sea ponds, the forage base and the ichthyofauna were investigated, the most valuable representatives of the ichthyofauna for amateur fisheries in these reservoirs were identified, the recommendations on the creation of a special cultural fishery on the Black Sea ponds were provided. It is established that the feed base in the Black Sea ponds for fish young is quite rich and varied. The current state of development of the forage base indicates the possibility of successful fishing activities and in particular the development of recreational fisheries. In case of intensification of economic activity there is a need to carry out a certain complex of fish-and-melioration works. As a result of the conducted researches it is established that the Black Sea ponds should be used for the creation of cultural fisheries for the purpose of organizing amateur fisheries, and the formation of ichthyocenosis should be carried out by purposeful fishing of valuable fish species suitable as objects of amateur and sport fisheries. Creating appropriate conditions for amateur fisheries as a popular way of recreational recreation of a large part of the population of Ukraine involves solving a number of biological, environmental and legal issues related to the reproduction and acclimatization of fish, the organization of sports and recreational fisheries, taking into account the characteristics of reservoirs, the impact of ecological and climatic conditions fisheries, etc.

The present study was conducted to know the present status of use of commercial aqua drugs and chemicals and their impact on fish health management in Jamalpur sadar upazila (sub-district). A questionnaire survey was conducted for a period of seven months from December 2013 to June 2014 from nineteen small scale fish farms, seven commercial fish farms, eight fish hatcheries and seven chemical retailers. Five categories of aqua drugs and chemicals were identified and noted in the study area. Those drugs and chemicals were produced by the following seven pharmaceutical companies: Square Pharmaceuticals Ltd., Novarties Animal Health, ACI Animal Health, Fish Tech BD Ltd., Acme Laboratories, Reneta, and Eon Animal Health. Different types of diseases such as edwardsiellosis, EUS (epizotic ulcerative syndrome), red spot and different parasitic diseases were found to occur in pangus (Pangasius hypophthalmus), tilapia (Oreochromis nilotica), sharputi (Puntius sarana), rui (Labeo rohita), mrigal (Cirrhinus mrigala), Thai koi (Anabas testudineus), shing (Heteropneustes fossilis) and silver carp (Hypophthalmicthys molitrix). Geotox, JV Zeolite, Aquakleen and Biomin Aquaboost were used for water quality management; Oxyflow, Bio Care and Oxylife to improve dissolve oxygen level; Megavit Aqua, Aqua Boost, Aquamin, Acimix Super-fish, Square Aquamix and Vitax-C as growth promoter; Oxysentin 20%, Captor, Aquamycine and Renamycin soluble powder as antibiotics; Hepaprotect-Aqua, Timsen, Virex, Polgard Plus as disinfectant; lime, salt, formalin, potash and malachite green were used against fish diseases. Susceptible months of disease outbreak in the study area were November to February. The recovery of fish diseases was found from 50% to 95% in Jamalpur region. Farmers’ poor understandings about the application of aqua drugs and proper withdrawal period were found in the study area which might have adverse effect on fish and human health. Proper training of fish farming community about the appropriate dose and administration methods should be suggested for safe and sustainable aquaculture practices.

Purpose. Investigate ecological conditions and determine fish productivity of ponds when growing young-of-the-year carp using a suspension of chlorella. Methodology. During the study, we used methods generally accepted in hydrochemistry, hydrobiology and fish farming. Findings. The article presents the results of the study on the use of chlorella suspension in the cultivation of carp. It was found that the use of chlorella suspension created favorable hydrochemical conditions resulting in intensive development of zooplankton, which had a positive effect on the growth of young-of-the-year carp and fish productivity of the pond. The development of the natural food supply was sufficient to meet the nutritional needs of juvenile carp. The average seasonal biomass of zooplankton in the experimental pond was 28.68 g/m3 that was 1.5 times higher than in the control. The share of cladocerans in the total biomass of zooplankton in the experimental pond was 76.6%, versus 36.8% in the control. The average biomass of zoobenthos for the growing season in the experimental was 1.3 times higher than in the control, and was formed by chironomid larvae, which are valuable in the food chain. Originality. The study investigated ecological conditions and fish productivity of growing ponds under conditions of the application of cattle manure and suspension of chlorella when growing carp in monoculture. Practical value. It was found that the use of chlorella suspension promotes the intensification of the development of zooplankton organisms in ponds. The obtained data can be used to develop practical recommendations for optimizing the conditions for growing carp seeds and increasing the biological productivity of ponds. Key words: nursery ponds, natural food supply, phytoplankton, zooplankton, zoobenthos, young-of-the-year carp, chlorella suspension, fish productivity.

The article describes the development of pasture lake fish farming within the forest-steppe Trans-Urals on the basis of improving the technologies of the fish-breeding process of one - year and two-year cultivation of commercial fish. Thanks to the introduction of integrated reclamation of lakes of the overseas type of the Trans-Urals and innovative fish farming technologies that use the reclamation effect of aeration of reservoirs in winter, loosening of bottom silt deposits during open water, the natural production potential of the lakes allowed to increase the fish productivity from 30-50 kg / year to 130-200 kg/ha per year. Based on the long-term monitoring of the ecological and fisheries situation of the lakes, it is recommended to intensify the process of modernization of existing fish farms and start creating new ones, which will significantly increase the importance of the Trans-Urals fisheries as part of the agro-industrial complex of Russia. It is recommended to include herbivorous fish – white Amur and white silver carp, and consumers of detritus and bottom silt-pilengas, which can effectively grow in salt water reservoirs, which are many within the southern Trans-Urals.
