Assessment of market parameters of multiple age groups of the galician carp

Purpose: To assess the productive potential of the Galician carp taking into account its morphometric parameters. To assess the market parameters of the Galician carp produced in the conditions of commercial aquaculture in ponds of the Subcarpathian region. To determine the output of fish products depending on fish age-related differences. Task: to determine major morphometric parameters in age-2 and age-3 cap produced at the end of the culture season in ponds of the Subcarpathian region; to assess the output of edible and non-edible parts of the body of the Galician carp. Methodology: The study was carried out in 2016 at the fish farm «Korop», Lviv region. The object of the study were age-2 and age-3 Galician carp produced at the end of the culture season. Fish were investigated according to methodical guidelines. The largest part of the body weight of the examined Galician carp was filet with skin. The smallest part in both age groups was scales that is due to the framed type of their scale covering. The quantity of edible parts in age-3 fish was 4.3% higher than in age-2 fish. The parameter of potentially edible parts in age-2 and age-3 fish was at the same level and did not exceed 32%. The non-edible part of the body in both age groups did not exceed 16%. In age-2 Galician carp, the edible part was 1.5% larger than in carp of the Lubin type of Ukrainian framed strain. In age-3 fish, the percent ratio of the head was 4.45% lower than in the Lubin type.  After analyzing the obtained experimental  data, a conclusion can be drawn that the output of edible parts in both age groups of the Galician carp from the marketable fish mass exceeded the normative values. At the same time, age-3 fish had 4% more filet than the age-2 fish. The Galician carp have a high level of the output of high quality market products compared to fish of the Lubin type of Ukrainian framed strain. An assessment of market parameters of the Galician carp produced during commercial culturing in ponds of the Subcarpathian region. The quantities of edible and non-edible parts in age-2 and age-3 fish of the examined array were determined.
