Abstract

It was revealed that the southern border of the range of spectacled sculpin Triglops scepticus runs in the region of 37°23′ N. It has been confirmed that the southern border of the range of Jordan’s sculpin T. jordani is located in the South Korean waters; of ribbed sculpin T. pingelii range, in the North Korean waters. In the Russian waters of the Sea of ​​Japan, Jordan’s sculpin occurs at depths of 14–230 m and water temperature of –1–13.8°C; ribbed sculpin, 30–424 m and –0.3–9.7°C; spectacled sculpin, 57–586 m and 0.3–4.3°C, respectively. In the warm period, the concentrations are somewhat shifted towards shallow waters; in the cold period, towards deep waters. The body length and weight of one-sized individuals increase with the degree of deep-water preference. The body length of Jordan’s sculpin reaches 20 cm; of ribbed sculpin, 23 cm; of spectacled sculpin, 26 cm. In all three species, females are larger than males. Females dominate populations of Jordan’s and ribbed sculpins while in spectacled sculpin the share of males is higher. In the northwestern part of the Sea of Japan spectacled and ribbed sculpins are planktivores consuming mainly hyperiids and euphasiids while Jordan’s sculpin is nectobenthivore with food dominated by mysids and small shrimps. During the spring—summer period mean values of daily rations of adult specimens of Jordan’s, ribbed and spectacled sculpins are 3.3, 2.4 and 1.8% of body weight, respectively. The biomass of g. Triglops species in the Russian zone of the Sea of Japan is about 2100 tonnes.

日本海三足目（Cottidae）的cul子的分布和某些生物学特性

摘要

据透露，眼镜鲈范围的南部边境Triglops scepticus在37°23'N.它的区域运行已确认的范围南疆乔丹的大头鱼T.的约旦位于韩国海域; 带刺的杜鹃T. pingelii范围，在朝鲜海域。在日本海的俄罗斯水域中，约旦的杜鹃发生在14–230 m的深度和–1–13.8°C的水温下；带肋的杜鹃，30–424 m和–0.3–9.7°C；带眼镜的鼻甲，分别为57–586 m和0.3–4.3°C。在温暖的时期，浓度有些偏向浅水区。在寒冷的时期，走向深水。一个人的体重和体重随着深水偏好程度的增加而增加。乔丹s头的身长达到20厘米；带刺的杜鹃花，23厘米；26厘米的带眼镜的头饰。在所有三个物种中，雌性大于雄性。雌性在乔丹和有肋骨的头饰种群中占主导地位，而在眼镜角饰的头饰种群中，雄性的占有率更高。在日本海的西北部，带眼镜和带肋骨的cul鱼是浮游动物，主要食用双节线虫和中性鱼，而约旦的cul鱼则是角鲨鱼，主要食物为my鱼和小虾。在春季至夏季，约旦，肋骨和带眼镜的杜鹃的成年标本的日定量平均值分别为体重的3.3％，2.4％和1.8％。g。的生物量。Triglops在日本海俄罗斯区的物种约2100吨。
