The article is focused on the problems of protection of biological resources and their habitats, the construction of new and improvement of existing fish breeding enterprises, the introduction of modern automation and mechanization of the most labor-intensive stages in the production of fish is a set of priority measures for the development of fish farming aimed at increasing fish production in inland freshwater bodies. Harvesting the fish ponds, regardless of their category, is a difficult and energy-intensive process. Choosing the type of fishing gear and fishing methods used to catch fish ponds primarily depends on the type of reservoir, the state of its hydraulic char-acteristics, as well as the type of fish caught and the time of year. The main categories of water bodies by the method of fish fishing and their features are considered. The used fishing gears are divided into 3 groups according to the principle of fish retention: entangling nets, strainers and sta-tionary gears (traps). It is noted that when fishing in the ponds, it is necessary to take into account the behavior and distribution of the fish. The effective methods for catching pond fish with different fishing gear are presented. The choice of the optimal fishing gear or device for fishing ponds will allow you to clearly plan and coordinate the work of the enterprise, since pond fishing is carried out in the shortest possible time, depending on the timing and needs of the market.

The research is aimed to reveal opportunity development of the capture fisheries in Talaud Islands Regency by using bionomy approach with Gordon-Schaefer model (Fauzy, 2005) con-cerning the dominant of illegal fishing activities around the area. The research was started by co-llected some secondary data on fish production and number of fishing units. Primary data were collected on catch composition and types of fishing gear. Gordon-Schaefer methods was applied to evaluate the tuna and skipjack resources in the area. The troll and pole and line are indicated as the dominant fishing gears used to catch the skipjack and tuna. In case of open access condition, the production will end up to 25,09 tons, while the resource rent will be end up to zero. For the development, simulations were exercised in 3 scenarios: 1) scenario of enhancing domestic fleet, 2) scenario of illegal fishing, and 3) scenario of net surplus. With those scenarios, if the illegal fishing could be eliminated, the capture fisheries in this regency could render economic value to 10 billion rupiah.

The use of the crop rotation method in fish farming makes it possible to increase fish productivity and crop yields in ponds. In the countries of the Middle East, in recent years, the Aqua Crop rotation practice has been developing, in particular, the consistent cultivation of fish and rice in fish ponds, which allows eliminating the contradictions between these crops and increasing production efficiency. In Iraq, an experiment was carried out on the variable cultivation of rice and carp in fish ponds for four years, with the aim of introducing this practice into the country’s agriculture. Four ponds, each with an area of 7.5 hectares, were involved. The research was carried out in two variants: in experiment No.1 rice was grown in the first year, fish in the second, then rice again and in the fourth year — fish, in the second experiment, on the contrary, at the beginning of the fish, then rice, etc. The fish-breeding season lasted 9 months (March to November). Fish-breeding indicators were studied in detail: survival rate, feed costs, fish productivity, the results of rice cultivation were judged by yield. In addition, indicators of economic efficiency were determined according to a simplified scheme. The results indicate that, in general, fish-breeding indicators turned out to be higher when growing fish in ponds after rice, so fish productivity increased by almost 30% with an average value of 3.9 t/ha, feed costs decreased, while rice yield increased by 15–16% and averaged 3.6 t/ha. The best fish-breeding indicators were obtained in the second experiment after rice was grown in the ponds for two years. Economic calculations confirmed the advantages of using the aquacrop rotation practice, so in the second experiment the cost of marketable fish decreased by 10%, and the profitability increased by almost 30%.

The article provides information on the most common invasive diseases of fish, which are the main objects of cultivation in aquaculture in Belarus, and information on new products developed by the employees of the RUE “Institute of Fisheries” RUE “Scientific and Practical Center of the National Academy of Sciences of Belarus for live stock breeding” to combat these invasions.Aquaculture of the Republic of Belarus is characterized by a global trend – an increase in fish production due to the cultivation of various types of fish in artificial conditions. In spite of the fact that today industrial-type enterprises are actively developing in Belarus (production is carried out under conditions of RAS or PSO), the main share of production, about 93%, falls on pond-type farms.Successful fulfillment of tasks to increase fish production, with constant pond fund areas, requires new solutions in such areas as working with new species of fish, conducting breeding work, developing balanced feed, improving fish farming technologies, studying microbiology and hydrobiology of ponds and so on.An important component of modern pond fish culture, which allows to significantly increase the yield and quality of fish products, is the ichthyopathological part. Due to the fact that production ponds have a close relationship with the biocenosis of natural water bodies, monitoring of invasive diseases in fish in both production ponds and the water source (the head pond, water sources flowing into it and nearby natural water bodies) comes to the fore. Monitoring of fish invasions in turn forms the need to develop ecological, highly efficient, and economically low-cost methods for the protection of pond fish.

Purpose: development of a layout-structural solution and technology for fish-breeding and reclamation complex operation for ecological improvement of phyto-contaminated reservoirs and fish farming in them. One of the urgent environmental problems typical for river and lake reservoirs is the overgrowth of their shallow waters with higher aquatic vegetation. Phyto-contamination of water bodies leads to a depletion of their ecological biodiversity, displacement of valuable species of aquatic flora and fauna, the decrease in their biological productivity and deterioration of conditions for various environmental management (water supply, fish farming, recreation, etc.). Rational and efficient use of natural resources cannot be ensured without ecological improvement of such objects. One of the directions of phyto-contaminated water bodies treatment is to carry out their biological reclamation by the introduction of herbivorous fish species into them. To increase the efficiency of such reclamation, it is proposed to create and use reservoir fish-breeding and reclamation complexes. Materials and Methods. The experimental and theoretical basis for the development of layout-structural solutions and technologies for the operation of such complexes was provided by known information and author's observations of the stocking of reservoirs. Results. The established shortcomings of the applied technologies led to the need to create the complexes that ensure the cultivation of fish stocking material adapted to the conditions of the stocking reservoir and the implementation of acclimatization measures for introducing herbivorous fish into the water body. Conclusions. The layout-constructive scheme and technology of fish-breeding and reclamation complex operation are proposed, which makes it possible to carry out the ecological improvement of phyto-contaminated reservoirs and, in general, to improve conditions, to increase the complexity, efficiency of using their resource potential and fulfillment of nature management.

Negative Effect

Fish ponds have been always built for purpose of fish farming and some additional functions. We evaluated fish farming operation (in years 1990–2007) on the Sykovec and Medlov pond in altitude 700 meters above sea level and Jaroslavický dolní pond in altitude 200 m. The samples for hydrochemical and hydrobiological analyses were taken regularly at monthly intervals in 2008. We chose some parameters as a total nitrogen (NT), total phosphor (PT), chlorophyll-a and chemical oxygen demand (COD) and structure of phytoplankton which has an impact on fish production. We compared our result with former research work from 1996–1997. Higher levels of monitored parameters have got a negative effect on spectrum of fish kind in managed fishponds.

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.
