Abstract
Based on ichthyological materials collected in 2022-2024 on the Samur coast of the Caspian Sea, the biological indicators of silver carp, red and perch are considered.
It is shown that in the years under consideration, the average indicators of length, mass, and age consistently decreased in silver carp and perch. In 2023, compared to 2022, these indicators increased for the red, but decreased in 2024, becoming lower than in 2022.
