Data on the extensiveness and intensity of infection of Kildin island cod with Echinorhynchus gadi in various seasons are given. E. gadi was proved to have a one-year life cycle and Gammarus duebeni as an intermediate host in the lake. A change of the parasite generations occurs in late summer--autumn. A high extensiveness (100%) and intensity of Kildin cod infection with E. gadi depends on the feeding habits (monophagy) and narrow distribution range of the host. Infection intensity is directly correlated with the fish age. Selfregulation of the parasite quantity in the host's intenstine is an important factor affecting the existence of E. gadi population in Lake Mogilnoye.
给出了基尔丁岛鳕鱼在不同季节感染多棘吻虫的广度和强度数据。已证明多棘吻虫有一年的生命周期，并且在湖中杜氏钩虾是中间宿主。寄生虫世代在夏末至秋季发生变化。基尔丁鳕鱼被多棘吻虫高度感染（100%）及其感染强度取决于宿主的摄食习性（单食性）和狭窄的分布范围。感染强度与鱼的年龄直接相关。宿主肠道内寄生虫数量的自我调节是影响莫吉尔诺耶湖多棘吻虫种群生存的一个重要因素。
