Characteristics of the ecological danger of illegal poaching fish catches in the lower reaches of the Irtysh river
Poaching of aquatic biological resources is one of the most common environmental crimes, causing direct and indirect harm to the entire amount of fish stocks.

Poaching of aquatic biological resources is one of the most common environmental crimes, causing direct and indirect harm to the entire amount of fish stocks. It is necessary to have a clear understanding of the composition and quality of poacher’s catches in order to properly manage fish stocks. This paper examines the poaching catches of the lower reaches of the Irtysh River, based on the data of forensic ichthyologic examinations over the past 9 years. The study showed that the basis of poaching catches is Siberian sturgeon, sterlet, ide, carpbream, nelma, burbot, less in demand, gibel carp, crucian carp, common roach, zander, perch, pike.
