A description of biotechnical methods of harvesting pike perch in natural reservoirs, methods of catching pike perch spawners, keeping in adaptation cages and transporting pike perch from fishing sites to the farm is given. Pike perch breeders were caught from the reservoirs with fixed and floating nets during the period: in the Kapshagai reservoir from 10 to 20 April; in the Syrdarya river — from April 20 to May 5. The adaptation was carried out in cages located in the coastal zone. Transportation to the fish farm was carried out in live fish tanks with a volume of 1 and 3 m³ with water aeration. The reproduction of pike perch was carried out in two fish farms of the Republic of Kazakhstan. The data on spawning of pike perch in two ways are given: in cages on nests; as well as the receipt of reproduction products by the factory method from “flowing” producers. In the first case, females and males were placed in cages in a ratio of 1:1 and 1:2; a spawning nest was installed in each cage and spawning was monitored. In the second case, from the “flowing” pike perch breeders ready for spawning, reproductive products (eggs and sperm) were obtained, fertilization and degluing were carried out with a suspension of white clay. The monitoring of hydrochemical indicators was constantly carried out, the dates of the beginning and end of spawning of pike perch were determined. The article presents the fish-breeding and biological characteristics of pike perch producers participating in spawning. The mass of spawned pike perch females in LLP “Halyk Balyk” ranged from 2 kg to 2.5 kg, males — 1.5–2.5 kg; females weighing 2.1–2.6 kg were used in the Republican State Enterprise “Kamyshly-Bashsky Fish Hatchery”; males — from 1.2 kg to 2.4 kg. Based on the results of the research, biotechnical standards were developed for the preparation of pike perch producers in water bodies, for transportation to fish farms, standards for spawning of pike perch in various ways.

Objective of research: to perform the parasitological monitoring we have to study the parasite fauna in fishes from different fish farm factories, calculate the index of similarity, estimate the influence of abiotic and biotic factors on the ecosystem of fish-breeding reservoirs. Materials and methods: parasitological monitoring of factory fish farms was conducted by the method of complete and incomplete parasitological examination taking into account the data obtained from various fish-breeding reservoirs. Results and discussion: the parasite fauna of cyprinid fishes is represented by 56 species, carriage of causative agents of parasitic diseases in fishes is detected. Index of similarity of parasite fauna in carps has been studied and typification of agricultural reservoirs carried out. Index of similarity between the parasite fauna in carp and herbivorous fish was 22–33 %, carp and rough fish - 18–30,7 %. Influence of abiotic (oxidability, reduction of oxygen and nitrogen ammonia concentration, mineralization) and biotic – anthropogenic factors (violation of processing technologies, veterinary and sanitary rules of fish transport and fish farming operations) on fish infestation with parasites was studied. The role of parasitological monitoring in prevention and elimination of fish diseases was shown.

Mixed Feeds

When growing fish in conditions of intensive technologies for normal growth and development, the main task is to provide them with a balanced full-fledged food. Currently, the most widely used in industrial fish farming are granulated mixed feeds of various formulations that fully meet the needs of the farmed fish. The objects of the study were the same-age sterlet fingerlings of ordinary color with an initial weight of 112–132 g and albino sterlet fingerlings weighing 99–105 g. We used mixed feeds from two manufacturers Aquarex (Russia) and Le Gouessant, which differ in fat content. Manual feeding. The temperature range is 21–23 °C. When feeding young sterlets of the usual color with the Aquarex compound feed, the average daily increase was 1.93 g, and when feeding with the Le Gouessant compound feed — 2.76 g, which is 43.0 % more. Albinos, on the contrary, had higher rates when fed with Aquarex compound feed — the average daily increase was 2.77 g, and on Le Gouessant compound feed — 2.13 g, which is 30.0 % lower. As a result of the conducted studies, it was found that the highest fish-breeding and biological indicators were achieved by sterlet fingerlings of the usual color when feeding them with Le Gouessant compound feed, and albino sterlets-when using Aquarex feed with a higher fat content. This indicates that for the successful cultivation of albino sterlets, mixed feeds with a fat:protein ratio of 1:2.5 should be used, and sterlets of ordinary color — 1:4.3, which should be taken into account when selecting mixed feeds, or making a diet.

Over recent years much attention has been paid to the fishery use of geothermal sources. The prospects for this area are enormous, as it opens up possibilities for managing fish-breeding processes, regardless of climatic conditions. The main objective of the research was a comprehensive study of the technological processes of growing. One of the promising reserves for increasing fish production is the rational fishery use of waste warm water and geothermal sources. Research work was carried out in 2019 based on the farm of “Tengri Fish” LLP, which is located 270 kilometers from Almaty. The collection and processing of materials were carried out according to generally accepted methods in ichthyology and fish farming, followed by their analysis on a PC. Based on the results of the research, technological primaries of growing tilapia in a RAS (Recirculating Aquaculture System) using geothermal waters were determined. During the research, work was carried out to optimize the hydrochemical regime. The main fish breeding and biological indicators for the growth and development of tilapia were established. The optimal stocking density of tilapias in recirculating aquaculture systems using geothermal waters and the temperature when tilapias have a higher average daily weight gain were found. The novelty of the research: a complex study of biology and adaptation of a new object of industrial fish farming of tilapia and clarium catfish has been carried out outside the range and determined the adaptation possibilities of tilapia and clarium catfish to extreme factors of the aquatic environment.

The elements of circular technologies in aquaculture on various types of energy are considered. The development of forms of aquaculture from pasture to industrial with an increase in the share of circular technologies is shown. It is noted that the use of cage fish farming on the waste warm waters of energy facilities is complicated by eutrophication at high fish planting densities and the peculiarities of temperature and hydrochemical regimes. The need to select new aquaculture objects with a fast growth rate, thermophilic and not demanding to the oxygen content in the water is noted: the African clarias catfish (Clarias gariepinus) is a promising object for growing in warm waters. The possibilities of including other representatives of catfish - shilbovye catfish (Pangasius) - are considered. It is shown that due to the expansion of biotechnologies for growing valuable objects in installations with a closed water supply cycle, thermophilic hydrobionts, for example, the Australian red-clawed crayfish Cherax quadricarinatus, can be used as elite delicatessen products. It is shown that the complex hydrobiocenosis of fouling is formed by a set of consults of different orders. A fish-breeding system with elements of circular technologies becomes similar in structure to a natural ecosystem. The results of experimental cultivation of spicy vegetable crops on the waste products of carp and clary catfish are presented. Aquaculture and aquaponics as specific components of the modern agricultural sector in development are focused on industrial production technologies with the use of circular technologies for the efficient use of resources.

The article describes aquaculture as a main factor saturating the domestic market with high-grade fish products in the world. In last decades, food production in this sector has increased by 12 times with an average annual increase of 8.8%. The Republic of Kazakhstan has rather high potential for developing different lines of commercial fish farming. Modern industrial fish farming is based on keeping fish in fully controlled water environments. In modern conditions, when fish are kept in cages and pools, natural feed is no longer of fundamental importance. Artificial feed is widely used; it should be balanced for the main nutrients and meet the needs of aquaculture facilities. There have been given data on nutrient requirements for the fish species that are new for aquaculture of Kazakhstan: larvae and juveniles of zander, tilapia and clarid catfish. There have been given the standards of adding components to the feed recipes, suggested the premix recipe for producing these feed and shown the quality parameters of starter feed for larvae and juvenile of zander, tilapia and clarid catfish developed in the Republic of Kazakhstan. The nutritional value of starter feeds for these fish species has been defined. Halyk Balyk LLP conducted the production tests in order to determine the effectiveness of using the feed and their uptake by the fry. Feed for trout Aller Agua produced in Denmark served as a reference. Research and business experiment showed that food coefficient of the feed prepared for clarid catfish (0.92) is slightly inferior to the imported feed, with fry survival rate at 71%, average daily increase at 54.3 mg. The designed recipes of starter feedstuff may solve the problem of import substitution for feed products in the country. The data on nutritional needs of the fish mentioned may be used to calculate the feed recipes for fish farms.

Strict Compliance

In two parts of the article, more than 70 errors and violations of the Biotechnics of artificial breeding of Pacific salmon in salmon hatcheries are collected and summarized, which lead to an immediate or delayed deterioration of the quality of reared fry and a decrease in their survival rate. Deviations from the biological basis of fish farming are shown and possible consequences of such errors or violations are predicted. In the first part of the article (#7,2020) there were General errors (throughout the entire fish-breeding process), as well as violations of Biotechnics during the work with producers, collecting eggs and preparing them for incubation, in the second part-violations of Biotechnics during the incubation of eggs, holding pre-larvae, rearing and release of young. Their correction, prevention or minimization of consequences will significantly improve the quality of sexual products and offspring from producers, increase the linear and weight gain of juveniles during rearing, improve the coefficient of feed payment, reduce the time of rearing, improve the epizootic situation by developing immunity in fry and mobilizing other protective reactions of their body, significantly reduce waste at all stages of the production process, increasing survival by 10–15%. In conclusion, it is noted that the first and most important condition for an efficient salmon hatchery is the creation of optimal environmental conditions at each stage of the production process. The second condition is strict compliance with the Biotechnics of artificial salmon breeding and the complex of veterinary and sanitary, fish-breeding and meliorative and therapeutic and preventive measures. The third is the availability of competent specialists who regularly improve their skills in accredited Universities to implement, control and manage the first two conditions.

The Impact

The main environmental problems associated with fish farming in Denmark are attributable to the dam, the “dead reach” and nutrient and organic matter discharge. The environmental regulation of fish farming in Denmark started with the Environmental Protection Act of 1974, the Statutory Order of 1985 forbidding wet feed, and the Action Plan on the Aquatic Environment of 1987. In the case of freshwater fish farms, the latter was implemented through the measures stipulated in the 1989 Statutory Order on Fish Farms. The impact of Danish legislative measures to reduce and regulate the environmental effects of freshwater fish farms can be summarized as follows: - the number of fish farms has been reduced from about 800 in 1974 to about 500 at present; - production has tripled since 1974 and has been stable since 1989; - a change from wet to dry feed has reduced the environmental impact of the farms; - the national goals of the Action Plan on the Aquatic Environment of 1987 for reducing fish farm discharges of organic matter, nitrogen and phosphorus have been fulfilled. The main remaining problems are that: - the local impact of fish farms on downstream stream quality is still much too high in about 15% of cases; - the problem of the passage of migrating invertebrates and fish is still unsolved at some farms; - the problems posed by “dead reaches” are still unsolved. It is concluded that sustainable fish farming is possible in Denmark, but with the present technology production will have to be significantly reduced.
