MORPHO-BIOLOGICAL CHARACTERISTICS OF ACCLIMATIZED SILVER CARP (HYPOPHTHALMICHTHYS MOLITRIX) IN THE WATER BODIES OF THE BUKHARA REGION
Abstract
This article analyzes the morphometric and plastic characteristics, growth rates, and condition factors (Fulton's coefficient) of silver carp (Hypophthalmichthys molitrix) acclimatized to the arid climate and unique hydrochemical composition of water bodies in the Bukhara region. Fish samples of various ages obtained from the Tudakul and Shurkul reservoirs, which are characterized by complex hydrochemical profiles, were selected as research objects. Based on statistical data, the article highlights the impact of the hot climate and high water mineralization (salinity) on the body structure and growth dynamics of the fish. Morphometric analyses conducted using the Pravdin methodology revealed the specific ecological plasticity and hydrodynamic adaptation traits of the acclimatized population. The research findings demonstrate that the hot climate and water mineralization levels significantly influence the morphometric indicators and overall productivity of the fish.
