Размножение и условия, определяющие урожайность поколений азовской тюльки в период 1993–2022 гг.Abstract
Variability in the yield of the Azov Sea tyulka (Azov Sea stocks of the Black Sea–Caspian sprat) generations affected by the environmental changes in 1993–2022 has been estimated. Stock assessments of the ichthyoplankton have been conducted in the Azov Sea in June for more than 50 years. Evaluation of the fingerling abundance is carried out in the course of the surveys with lampara nets in August. During the survey period, considerable environmental changes attributable to natural and anthropogenic factors have been identified; they heavily influence the yield of the Azov Sea tyulka generations.Дана оценка колебаний урожайности поколений тюльки в связи с изменениями условий обитания в период 1993–2022 гг. Исследования по оценке численности ихтиопланктона проводятся в Азовском море в июне более 50 лет. Учет численности сеголеток осуществляется в учетной лампарной съемке в августе. В течение анализируемого периода выявлено, что произошли значительные изменения условий, вызванные природными и антропогенными факторами, которые определяют урожайность поколений тюльки.
