Abstract
Nematoda parasites of five greenling species from the Far-Eastern Seas ( Pleurogrammus azonus , P . monopterygius , Hexagrammos octogrammus , H . lagocephalus , H . stelleri ) are investigated. The family Hexagrammidae is endemic for the North Pacific. In total, 10 species of nematodes are found: Anisakis simplex l., Pseudoterranova decipiens l., Hysterothylacium aduncum , Contracaecum osculatum l., Ascarophis filiformis , A. curvicauda , A. pacifica , Cucullanellus minutus , Cucullanus heterochrous , and Paracapillaria helenae , all of them have wide geographical and hosts distribution. Anisakis simplex l. and Pseudoterranova decipiens l. are the most common for all investigated host species. The highest species diversity of nematodes (7 species) is registered for arabesque greenling P. azonus , particularly its females; Contracaecum osculatum l. and Cucullanus heterochrous are found for the first time for this host in the Japan Sea. The parasites are dispersed irregularly in muscles of all parts of fish body. Large-sized (i.e. elder) fish is higher infected by larvae of P. decipiens .

Summary
Приводятся данные по нематодофауне 5 видов терпугов (Pleurogrammus azonus, P. monopterygius, Hexagrammos octogrammus, H. lagocephalus, H. stelleri). Всего выявлено 10 видов нематод: Anisakis simplex l., Pseudoterranova decipiens l., Hysterothylacium aduncum, Contracaecum osculatum l., Ascarophis filiformis, A. curvicauda, A. pacifica, Cucullanellus minutus, Cucullanus heterochrous, Paracapillaria helenae. Общими для всех исследованных видов рыб являются Anisakis simplex l. Для учета наиболее зараженных частей мускулатуры тело рыбы делили на спинную и брюшную части. Ключевые слова: нематоды, терпуг, зараженность мускулатуры, дальневосточные моря, Anisakis simplex l., Pseudoterranova decipiens l. Nematoda parasites of five greenling species from the Far-Eastern Seas (Pleurogrammus azonus, P. monopterygius, Hexagrammos octogrammus, H. lagocephalus, H. stelleri) are investigated. 10 species of nematodes are found: Anisakis simplex l., Pseudoterranova decipiens l., Hysterothylacium aduncum, Contracaecum osculatum l., Ascarophis filiformis, A. curvicauda, A. pacifica, Cucullanellus minutus, Cucullanus heterochrous, and Paracapillaria helenae, all of them have wide geographical and hosts distribution. Настоящая работа посвящена обобщению многолетних данных по зараженности массовых видов терпуговых северо-западной части Тихого океана
