Abstract: Wide breeding of peled (Coregonus peled) began in the lakes of Western Siberia in the 1960-s. A lot of lakes were stocked yearly. Total catch of fish exceeded 5 000 tons during fishery arrangement with the share of peled about 90%. Now the amount of 1,400 tons of peled are planting yearly. We study the data set collected for the last 40 years about peled culture in the lakes of Ural and Western Siberia. Till now, MDA methods have not been applied for data processing of Russian fish culture industry. The goals of the research are: the explanatory analysis of MDA methods feasibility in fish culture and prediction of whitefish breeding effectiveness in the Tobolsk region lakes. Steps of analyses: 1) Construction of the PCR model on the whole data set. The results show essential difference between lakes located in different regions. Distinct clusters may be seen in the score plots. 2) For one cluster (Tobolsk region lakes) the PLS1 model is used for prediction of fishery yield. 3) For the groups of lakes with total square less then 60 sq. km, the PCA model helps to analyze the influence of lake conditions on productivity. Software Unscrambler 8.0 was used for data analysis.
