    Description: Recruitment to the vimba bream (Vimba vimba natio carinata (Pall.)) population with juveniles in the Azov Sea Basin occurs through both natural and artificial reproduction. This work presents the results of long-term studies aimed at the assessment of artificial reproduction and rearing the juveniles of vimba bream in the Azov Sea and Don River Region. The quality of the juveniles released into a natural water body has been assessed based on their morphometric characteristics and the chemical composition of their muscle tissue. The criteria for quality assessment based on the fat, protein, and ash content have been established. The correlation between morphobiological characteristics and fecundity has been identified; the equations for calculation of some parameters, such as weight of the gonads and estimated operational fecundity, have been derived. The recruitment to the stocks of aquatic biological resources with vimba bream juveniles for the last 7 years (2015–2021) is presented.
    Description: Пополнение популяции рыбца (Vimba vimba natio carinata (Pall.)) Азовского бассейна молодью осуществляется в т. ч. и за счет искусственного воспроизводства. В работе представлены результаты многолетних исследований по оценке искусственного воспроизводства молоди рыбца в Азово-Донском районе. Дана оценка качества выпускаемой в естественный водоем молоди по морфометрическим показателям и показателям химического состава мышц. Определены критерии оценки качества по содержанию жира, белка, золы. Выявлена корреляционная зависимость между морфо-биологическими показателями и плодовитостью, выведены формулы для определения отдельных показателей, таких как вес гонад, расчетная рабочая плодовитость. Представлен объем пополнения водных биологических ресурсов молодью рыбца за последние 7 лет (2015–2021).
