STUDY ABOUT CORPORAL INDICATORS IN JUVENILE OF RUSSIAN STURGEON (ACIPENSER GÜELDENSTAEDTI) RAISED IN RECIRCULATING SYSTEM
Keywords:
Acipenser güeldenstaedt, corporal indices, RASAbstract
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.
