Abstract
The article presents the results of a long-term (1990–2024) study of the fish species composition of the lower reaches of the Neman River within the Kaliningrad Oblast, based on the analysis of commercial and scientific catches. A total of 42 species of fish and fish-like species were identified. Differences in species diversity depending on the type of fishing gear (scientific vs. commercial) and season are demonstrated. The most complete data on species composition were obtained using a combination of scientific fishing gears during the spring season. A logarithmic relationship was established between the number of hauls and the number of species detected: describing the complete ichthyofauna of a large river requires more than 3000 hauls per year. The presence of invasive species (round goby, monkey goby, Amur sleeper) is noted.
