ABSTRACT
Aim of the study:
The aim of the work was to use the Rembrandt multicriteria decision support method to select the best type of fish pass for the analyzed barrage, depending on the priorities used.

Material and methods:
Hydraulic structures interrupt the continuity of morphological and biological watercourse, divide it into sections, where the borders of fish and other aquatic organisms can not exceed. It is particularly disadvantageous because they are moving as a result of various necessities of life. That is why fish pass are built on the barrage to facilitate their migration. The work was carried out hydraulic calculations assumed for the three types of fish passes. Next, a hierarchical tree was prepared in accordance with the Rembrandt method. This tree has been resolved three times in accordance with the investor's preferences, the organisms that use it, and without imposing a second level of calculation on weights.

Results and conclusions:
The results of calculations using Rembrandt's multi-criteria decision support method indicated that according to the investor's priorities the best pass was the slot passes, for water organisms the bypass channel, and for calculations in which the balances assumed equal values for individual level II factors also the slot passes.
