Significant Damage

The influence of ecological, epizootological and technological factors on fish health was studied. It is shown that disregard of environmental, technological and veterinary-sanitary requirements in the reproduction and cultivation of fish leads to the emergence of contagious and non-contagious diseases and causes significant damage to fish farming. The analysis of previously approved veterinary and sanitary rules, instructions, recommendations for breeding and commercial fish farms, as well as patent documentation and scientific publications in the field of ecological and veterinary research in fish farming is carried out. The possibility of using modern ecological and veterinary-sanitary achievements for the protection of fish health is shown. The complex system of preventive measures (organizational, environmental-technological and veterinary-sanitary), supplemented by modern ecological and veterinary achievements, in its implementation will allow to reduce losses of fish products and increase efficiency of production.

A robust body of evidence has demonstrated that the lunar cycle plays an important role in the reproduction of fish living in natural environments. However, little is known about the influence of the moon on tilapia reproductive activity in intensive fish farming systems. This study aims to evaluate the influence of the lunar cycle on the reproductive performance of tilapias in an intensive outdoor tropical production system in Latin America. Records of two tilapia strains (Nile tilapia [ Oreochromis niloticus; n = 75] and Red tilapia [ Oreochromis spp.; n = 1335]) reared in concrete tanks in a commercial fish farm were analyzed. Over a 3-year period, 60,136 captures were made in intervals of 12 to 14 days and 6,600 females were manually spawned. The number of females spawned and the volume of eggs collected from each tank ( n = 9) were recorded. Data was analyzed by the general linear model and means were compared by least squares means method. A very slight or no variation was observed when the lunar cycle was split into two halves (crescent and waning). The proportions of females spawned and the volume of eggs per spawned female and per female in the tank varied considerably across the eight periods of the lunar cycle, with greater values in the waning than in the crescent phase. A significantly greater proportion of tilapia spawned and yielded more eggs around the full moon than around the new moon and remaining days of the lunar cycle. The moon cycle affected the reproductive activity of tilapia, which were more reproductively active around the full moon and most of the waning phase.

The state program “Development of aquaculture (commercial fish farming) in the Russian Federation for 2015-2020” (hereinafter referred to as the State Program) determines the main directions for the development of the fisheries complex and its financial support. However, the current program does not sufficiently elaborate the forms of state support for this sphere of agricultural production, which would contribute to the accelerated development of the industry. It should also be noted that the existing potential of aquaculture in Russia is not fully utilized. The Institute of Economics of the Irkutsk State Agrarian University named after A.A. Ezhevsky, in collaboration with the Ministry of Agriculture of the Irkutsk Region, assessed the fulfillment of tasks of the State Program, identified factors hindering the development of aquaculture in Russia and its regions, and developed recommendations for improving the forms of state support for economic entities in the industry.

The paper presents the results of artificial reproduction of sterlet (Acipenser ruthenus Linnaeus) carried out at the Scientific Production Center KazakhOsseter, LLP (the Mangistau region) in conditions of a recirculating aquatic system (RAS). The conditions for carrying out the main reproduction measures are described: wintering, qualifying, hormonal stimulation, obtaining reproductive products and rearing larvae. As a result, the sterlet spawning campaign was carried out in conditions of RAS in the Mangistau region, the native grown viable sterlet larvae being obtained. In the course of the work carried out in conditions of RAS in the Mangistau region there have been developed the scientific foundations and technologies for the formation and using production stocks of sturgeon, which are involved in the process of artificial reproduction. The results of the work performed could help to effectively organize the production at the commercial fish farming enterprises in the Mangistau region. The entrepreneurs of the region will have the opportunity to get acquainted with the technology of fish growing in conditions of RAS and to apply the technology for obtaining and reproducing sturgeon species in the ir local hatcheries in the future.

Abstract The analyze of dynamic of quantity and composition of the Russian catches in the Sea of Azov, Black and Caspian Seas in the 21st century was made. It has been shown that catches decrease with a simultaneous increase in the proportion of marine fish proper. The analyze of aquaculture development in southern regions is provided and also identified the prospects for its development in the near future. Currently, there is a positive dynamics of growth in the production of commercial fish farming products. Since 2000 this parameter has decreased from 77 to 328 thousand tons in 2020. The volume of aquaculture in the southern regions of the country in 2020 amounted to more than 78 thousand tons, which is 24% of the total Russian. In Rostov and Astrakhan region, Krasnodar territory obtained 90.6% aquaculture production. The perspective ways are pasture aquaculture, ponds and industrial fish farming, recreational aquaculture, mariculture. The expansion of the species diversity of farmed fish is possible both due to the aboriginal ichthyofauna and the use of previously acclimatized species.
