This investigation examined the behavioral responses of freshwater mussels to neonicotinoid pesticide exposure, a widely implemented agricultural crop protection agent. The study systematically evaluated modifications U. tumidus under controlled laboratory conditions, with particular emphasis on shell dynamics and activity patterns during both acute (2.5 h) prolonged (20 exposure imidacloprid at 50 µg/L concentration. experimental findings revealed consistent statistically significant alterations. Upon initial specimens exhibited an immediate reduction in aperture, followed by sustained period enhanced opening amplitude. Activity metrics demonstrated elevation immediately post-exposure, indicative stress-induced responses, subsequently achieving homeostatic equilibrium before declining later temporal phases. These statistical significance across all four iterations, indicating robust reproducible stress response pattern. that high concentrations significantly affects mussel causing significant, repeatable changes behavior: closure increased activity, subsequent toxic effects.
