Economic efficiency of growing commodity trout in farms in the Western Ukraine while feeding with forages Aller Aqua
Fish farming, as an agricultural sector, plays an important role in providing people with valuable food. In order to maintain fish stocks in reservoirs at the industrial level, the introduction of additional industrial species, as well as their hybrid forms, is important. Growing trout is promising in Ukraine, especially in the western region. The urgent task for modern freshwater fish farming in Ukraine is the restoration of effective development of trout fishing. An increase in the production of high-quality trout products in Ukraine will make it possible to significantly reduce imports of salmon fish. According to the working meeting of the trolling development team in Ukraine, held on September 6, trout growing in the Ukrainian market reached 6 thousand tons, while 10 thousand tons per year of grown trout is the absolute minimum that can be grown. In our country trout is not a traditional breeding object, its production is only 1.5% of all species of fish. The increase in the production trout fishing of products is possible due to the expansion of production areas, the integration of production processes, the transfer of experience from foreign producers, as well as investments in the fishing industry, which would allow small farms to supply domestic products to the market. An important moment in the development of profitable trout farms is the definition of the optimal commodity weight of trout. So in foreign trout fishing, small trout is not realized. Freshwater economies in Germany, Denmark, and Turkey face high feed costs and relatively low productivity. In the US, for example, during the year the trout reaches a mass of 410–450 g; in Japan, rainbow trout weighing 100–120 g is used as a landing material for garden cultivation in seawater, which is carried out from October to July next year at a water temperature of 8–14 °C. At the end of the period, the fish grown up to 2 kg. Growing rainbow trout as commercial fish in trout farms is organized with different terms of implementation, depending on the different weight of fish. Currently, trout is considered to be commodity in Ukraine with an average weight of 250–350 g. But given the current state of the market of fish products, it is not feasible to sell such fish because it does not show its food and taste preferences and does not have a commodity condition. Along with this, in the commodity trout weighing 500 g or more, except for meat, caviar are a valuable food product. Fishery productivity is a key indicator of the efficiency of farm fish farming and reflects the state of technology and production culture, and the level of management affects all economic performance of the fish industry. In modern trout fishing, traditional feeds are finally replaced with highly effective granulated dry feed mixes. Therefore, the purpose of our work was, based on a review of literary sources and analysis of the economic activity of the investigated farms, to give a general description of the forage for Aller Aqua, which is used for fish feeding, and to determine their effectiveness.
