Commodity qualities of rainbow trout grown on feed “Aller Aqua”

Keywords: rainbow trout, feeds of Aller Aqua companies, Biomar, balanced nutrition, biochemical parameters, amino acid composition, lipid composition, morphometric evaluation


Growing trout under closed water supply is linked to economic issues such as high planting density per unit area and the choice of granular feed, which in terms of value should be inexpensive and fully meet the needs of fish with all the necessary nutrients and nutrition. This approach is reflected in the materials of the scientific and practical publication on the intensity of growth and assessment of marketable qualities of trout for use in the feeding of granulated compound feeds of the firm “Aller Aqua”. Scientific research consisted in determination of morphometric indices of different age groups of trout, studies of chemical, amino acid and lipid composition of tissues, which allowed us to draw conclusions about the efficiency of feeding fish with the investigated feed. The research and production experiment was conducted in the conditions of PJSC “Bilshevtsi-Fish”, located in the village Bilshevtsi of Ivano-Frankivsk region. In order to study the effect of different types of compound feed on the exchange processes in rainbow trout, three-stage studies were conducted. The research is based on a comparative assessment of the impact of the above granular feed on the overall functional state of fish growth and quality indicators of the products obtained. The selection of appropriate feed for the rational supply of fish needs with all the necessary nutrients is of particular importance in the planned production of salmon fisheries, the demand for which is constantly growing in human nutrition. Therefore, the nutrients contained in the feed should not only support the vital activity of the organism, but also promote its growth and ensure the normal functioning of the whole organism. The feed used granular feed from the manufacturer Aller Aqua and Biomar, the recipe and the diameter of the granules according to the age and weight of the fish. Feed composition and nutrition were consistent with the period of fish cultivation. The daily rate of feed was calculated in accordance with conventional methods in fisheries, taking into account the temperature of the water and the weight of the fish. The purpose of the study was to study the effect of the tested feed on the functional state of growth, biochemical parameters of muscle tissue and liver. Only healthy fish without visible damage, which were caught immediately prior to the study, were used for the study and were not fed for 24 h. During the research, the main linear indicators were determined using conventional techniques in fisheries. The conducted studies allow us to conclude on the direct link between the marketable qualities of rainbow trout and the feed consumed, their quality composition and nutritional value. In addition, the influence of abiotic factors, which were the same for all trout groups studied, were considered, which are equally important and, along with rational feeding, occupy a key place in production.
