Системный микоз у кеты вызвали митоспоровые грибы Phoma sp. Тяжелая вспышка триходиниоза была связана с токсическим воздействием поверхностно-активных веществ, снижающих защитные функции кожи рыб. У чавычи повышенная смертность оказалась следствием алиментарной патологии. Результаты исследований показали, что комплексный подход имеет решающее значение для идентификации патогена и в целом для диагностики, лечения и профилактики заболеваний у молоди на ЛРЗ.</p></abstract><trans-abstract xml:lang="en"><p>An integrated approach based on histological, bacteriological, virological, parasitological, and hematological methods was employed between 2022 and 2024 to diagnostic of etymologically different diseases in juvenile Pacific salmon in salmon hatcheries of Kamchatka. Systemic mycosis of chum salmon was caused by the mitosporic fungi Phoma sp. A severe outbreak of trichodiniosis was linked to the toxic effect of surfactants, that reduced protective function of the fish skin. Increased mortality of Chinook salmon was a consequence of alimentary pathology. Results of the research demonstrate that integrated approach is crucial for identification of pathogen and, overall, for making diagnosis, treatment, and effective prevention of diseases in hatchery juveniles.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>диагностика</kwd><kwd>системный микоз</kwd><kwd>триходиниоз</kwd><kwd>тихоокеанские лососи</kwd><kwd>аквакультура</kwd><kwd>алиментарные нарушения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>diagnostic</kwd><kwd>systemic mycosis</kwd><kwd>trichodinosis</kwd><kwd>Pacific salmon</kwd><kwd>aquaculture</kwd><kwd>alimentary disorders</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Гаврюсева Т.В. 2007.
