The aim of this work is to compare the temperature influence on activity level of the digestive enzymes of the intestinal mucous tunic of Russian sturgeon, Siberian sturgeon and their hybrid ROLO. There have been studied four enzymes – α-amylase, maltase, alkaline phosphatase and total proteinases researched in the temperature range from 0 to 60 °С. The main method of the data processing was multidimensional scaling. In the capacity of the method of estimation of the distances between multidimensional variables which contain information about activity level under the temperature influence the city-block distance was used. After the data processing by nonmetric multidimensional scaling of the experimental data studied variables were plotted on the two-dimensional map. Values of the stress-function and alienation coefficient were 0.045 and 0.059 accordingly which is indicative of correctly computed conversion of the initial distances. There has been demonstrated that reactions of the digestive enzymes of the hybrid under the influence of different temperature are the most similar with the enzymes of Russian sturgeon. In all cases data containing information about influence of moderate and low temperature on enzymes and analogical data about high temperature are in different clusters which signify about essential changes of adaptive reactions of the enzymes. Data of influence of temperature 60 °С are moved away from the main data array. The conclusion about prospects of application of multidimensional scaling for the complex data analysis in the ecological physiology when multidimensional experimental data array processing is made.
