ABSTRACT


In the present paper changes of biometric characters
of a total of 249 juvenile specimens of Siberian sturgeon in the heated water
culture are discussed. Investigations were made on specimens from
0+ and 1+ age groups in the five total length classes. The analysis involved
11 meristic and 34 metric characters. In addition, the analyses of the so-called
Soljan index – SOLJ, the relative position of barbels CA, width of snout FB as well as the length and weight of fish were performed. Most of the metric characters of the Siberian sturgeon show an allometric growth affected
by the specific conditions of culture. Meristic characters of the species examined
in the aquaculture are subjected to the significant variability in different
directions.

Key words: aquaculture, meristic and metric characters, morpho-monitoring.
