В рамках исследований изучены репродуктивные показатели Bufotes boulengeri. Материалом послужили кладки, полученные в лабораторных условиях от жаб разного возраста – от 2 до 7 лет. Средняя плодовитость самок жабы Буланже составила 2489.4±152.9 яиц (размах – 484-4816). Самая высокая плодовитость была зафиксирована для 4-летних самок – 3507.6±272.9 яиц. Периодом высокой репродуктивной активности можно считать возраст c 3 до 6 лет, после чего плодовитость падает. Диаметр яиц и ширина икряных шнуров подвержены изменениям, однако возрастных тенденций выявить не удалось.

This study investigated the reproductive performance of Bufotes boulengeri. The material analyzed consisted of egg clutches obtained under laboratory conditions from toads of varying ages, ranging from 2 to 7 years. The mean fecundity of female Boulenger's toads was determined to be 2489.4 ± 152.9 eggs (range: 484-4816). The highest fecundity was recorded for 4-year-old females, averaging 3507.6 ± 272.9 eggs. The period of high reproductive activity appears to be between 3 and 6 years of age, after which fecundity declines. Although the egg diameter and egg string width showed variation, no clear age-related trends could be established for these parameters.
