Материал собран в ходе комплексных донных траловых съемок в летне-осенние (2010, 2012 гг.) и весенний (2018 г.) периоды. Установлено, что скопления вида приурочены к глубинам 540–980 м с температурой от 0 до 2 оC. Выявленное преобладание самцов относительно самок в уловах следует интерпретировать с осторожностью в связи со спецификой уловистости орудий лова (соотношение полов от 1,00 : 0,16 до 1,00 : 0,69 и их биомассы 596–1002 кг/км2 у самцов против 55–189 кг/км2 у самок). Диапазон размеров ширины карапакса у самцов составил 12–171 мм, у самок – 17–99 мм. Методом аллометрии клешни определены размеры наступления функциональной зрелости у самцов: CW50 = 100,8 мм, CW75 = 112,9 мм, CW100 = 151,7 мм. Размер CW50 для впадины ТИНРО превышает показатель для популяции восточной части Берингова моря (91,4 мм), что свидетельствует о более позднем созревании. Первично оценены параметры роста: предельная ширина карапакса составила 147,2 мм для самцов и 81,6 мм для самок; расчетный размер физиологической половозрелости – соответственно 67,5 и 49,4 мм. Выявлена четкая сезонная динамика, а именно линька самцов достигает пика в конце весны – в начале лета, а репродуктивный цикл самок синхронизирован и характеризуется доминированием особей с наружной икрой, отложенной на плеоподы в летне-осенний период.</p></abstract><trans-abstract xml:lang="en"><p>Biology of triangle tanner crab Chionoecetes angulatus in the deep-water TINRO Basin (Okhotsk Sea) is studied in details on the data collected in comprehensive bottom trawl surveys in summer-autumn (2010, 2012) and spring (2018) seasons. Aggregations of the species were found at the depths of 540–980 m, under temperature 0–2 оC. Males dominated over females in catches (sex ratio ranged from 1.00 : 0.16 to 1.00 : 0.69, the ranges of biomass were 596–1002 kg/km2 for males versus 55–189 kg/km2 for females), possibly because of specific catchability of the trawl gear. The carapace width (CW) was 12–171 mm for males and 17–99 mm for females. The size levels of functional maturity were determined for males with the method of claw allometry as: CW50% maturity 100.8 mm, CW75% maturity 112.9 mm, and CW100% maturity 151.7 mm. The CW50 value in TINRO Basin exceeds this level for the population in eastern Bering Sea (91.4 mm) that indicates later maturation of the crabs in Okhotsk Sea. Growth parameters were estimated for first time: the maximum carapace width of 147.2 mm for males and 81.6 mm for females and the size of physiological sexual maturity of 67.5 mm and 49.4 mm, respectively. Clear seasonal patterns were identified, namely moulting of males with the peak in late spring or early summer and synchronous reproductive cycle in females with external eggs laid on pleopods in summer-autumn.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>краб-стригун ангулятус</kwd><kwd>Chionoecetes angulatus</kwd><kwd>Охотское море</kwd><kwd>впадина ТИНРО</kwd><kwd>рост</kwd><kwd>линочный цикл</kwd><kwd>половое созревание</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Chionoecetes angulatus</kwd><kwd>Okhotsk Sea</kwd><kwd>TINRO Basin</kwd><kwd>growth</kwd><kwd>life cycle</kwd><kwd>sexual maturation</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Авторы выражают искреннюю признательность П.Ю.
