Studies on the accumulation of manganese in females and males in the scales and muscle tissue of the Sander lucioperca of the Novosibirsk Reservoir were carried out. Analyzes were taken in a A.M. Nikolaev analytical laboratory of the Institute of Inorganic Chemistry SB RAS. The pike perch were divided by gender. Then 34 samples of scales and muscle tissue were taken from them. The manganese content was determined by inductively coupled plasma atomic emission spectrometry on a Thermo Scientific iCAP-6500 spectrometer. High variability of manganese accumulation in females and males in scales and muscle tissue was revealed. It was found that the concentration of manganese in females scales was 7.7 times higher than in muscle tissue, and in males - 15.7 times. There were no significant differences in manganese content between the genders. The ratio of extreme variants of scales in females and males was 1: 5 and 1: 6, and in muscle tissue - 1: 35 and 1: 30, respectively. The average values of the concentration of manganese in the muscles of the Sander lucioperca of the Novosibirsk reservoir were determined. Differences in the deposition of manganese in muscle tissue in females and males of Sander lucioperca were revealed. The concentration of manganese in the muscles of females was 2 times higher than that of males. The results obtained on the accumulation of manganese in scales and muscle tissue can be used as reference values. The level of metal concentration is characterized by an uneven distribution in the muscles and scales of Sander lucioperca. The research results are suitable for a lifetime assessment of the Sander lucioperca interior. An average positive correlation was found between manganese in females with absolute length and body weight (r = 0.329 and r = 0.311). It was found that the amount of manganese and other heavy metals in the Novosibirsk reservoir is increasing.
