| Popis: | Studies were conducted on a population of Russian sturgeon (Acipenser güeldenstaedti) age between 132-175 days, raised in recirculation system. Based on body weight, the population was divided into two categories: 50-100 g and 100-150 g. On the 42 individuals were performed determinations of weight, length, width, height and circumference. It was also determined the number of shields which comprise the five lines of shields, which are endowed with Russian sturgeons. On the basis of weighing and measurements taken have resulted following body indices: the index of profile (height), the index of thickness (width spinal), the fattening index (Fulton index), quality index and the index of fleshiness. At the lot of Russian sturgeons with average body weight of 127.55 ± 3.75 g, body length is 76.27% of total body length, head length is 20.11% of the total length of the body, caudal peduncle length measured 16.39% of total body length and length of snout reaches 45.56% of head length. Index of profile (height) has highlighted that juvenile Russian sturgeon has an elongated body and a straight back. |
