Purpose. Definition and analysis of biological criteria for qualified materiality harm caused by the fishing industry as a result of illegal extraction of water biological resources.

Methodology. The calculations were carried out for the top of the Kanev reservoir and were based on data from the Water of Life reserves the Kanev reservoir identified Institute of Fisheries NAAS within acceptable elaboration of industrial catches for 2013 year. Index of an average natural mortality were determined by the method of P. V. Tyurin. In the calculations indicators used listed in the acting regulatory and technical literature.

Findings. As a criterion for determining the materiality of damage used daily natural mortality rate, which is accepted at 0,1 % of the balance. It is established that for certain types of top of the Kanev reservoir extraction already 1 ind., can lead to consequences that are assessed as significant. However, the simultaneous extraction of several species in an amount which is less than the limit also requires evaluation from the standpoint of materiality. To this end, proposed criterion is expensive - in calculating losses greater than 266 tax-free minimum incomes of citizens, damage fisheries can be considered significant.

Originality. First proposed procedure for assessing the impact on the ichthyopopulation of illegal fishing from the standpoint of materiality damage.

Practical value. The results are used in the preparation of expert reports for regulatory environmental agencies.

Keywords: ichthyofauna, natural mortality, illegal removal, harm to fisheries.
