Материалом для работы послужили 99 живых особей байкальского омуля. Для каждого экземпляра проводили измерения силы цели в садке с помощью эхолота EY500 фирмы Kongsberg Simrad и исследования морфологии плавательного пузыря. Измерения, анализ изображений и данных проводили с использованием программных ресурсов Image Pro 6.0,Exel и SciLab.</p></sec><sec><title>Результаты</title><p>Результаты. Определены основные морфологические характеристики плавательного пузыря байкальского омуля и установлены зависимости размеров и его пропорций от длины тела рыб. Рассчитанные на основе результатов модели акустического рассеяния вытянутого сфероида коэффициенты уравнения TS=20log(SL)–60 хорошо согласуются с коэффициентами по максимальным значениям, полученными в условиях садкового эксперимента. При пересчете коэффициентов с учетом аллометрических изменений длины плавательного пузыря относительно длины рыбы получено уравнение TS=23,2log(SL)–64,4. Выполнен сравнительный анализ имеющихся уравнений силы цели для байкальского омуля с полученным в данной работе.</p></sec><sec><title>Заключение</title><p>Заключение. Уравнение, полученное на модели плавательного пузыря как вытянутого сфероида, адекватно описывает зависимость максимальных значений силы цели от длины тела байкальского омуля, подтверждает полученную ранее зависимость по максимальным значениям TS в условиях садкового эксперимента и может служить основой для дальнейших теоретических изысканий.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. The aim of the study was to estimate the coefficients of the equation TSmax=f(SL) considering the characteristics of an acoustic scattering model based on the morphological characteristics of the swim bladder of the Coregonus migratorius (Georgi, 1775). </p></sec><sec><title>Material and Methods</title><p>Material and Methods. Ninety‐nine living specimens of C. migratorius served as the study material. For each specimen, the target strength in the cage was measured using an Kongsberg Simrad EY500 echo sounder and the morphology of the swim bladder was studied. Measurements, analysis of images and data were conducted using Image Pro 6.0. Excel and SciLab software resources. </p></sec><sec><title>Results</title><p>Results. We determined the main morphological characteristics of the swim bladder in C. migratorius as well as the correspondence of its dimensions and proportions in relation to the length of the fish’s body. The coefficients of the equation TS=20log(SL)‐60, calculated on the results of the acoustic scattering model of a prolate spheroid, agree well with the coefficients calculated from maximum values obtained in the cage experiment. During the conversion of the coefficients relating to the allometric changes in the length of the swim bladder relative to fish length, the equation TS=23.2log(SL)‐64.4 was obtained. A comparative analysis of the available equations of the target strength for C. migratorius with those obtained in the study was undertaken. </p></sec><sec><title>Conclusion</title><p>Conclusion. The equation obtained on the model of the swim bladder as a prolate spheroid adequately describes the dependence of the maximum values of the target strength on the body length of the C. migratorius and confirms the previously obtained dependence by maximum values of TS in the cage experimental conditions and can serve as a basis for further theoretical studies.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>Байкальский омуль</kwd><kwd>оценка запасов</kwd><kwd>акустическое рассеяние</kwd><kwd>сила цели</kwd><kwd>эффективная площадь поперечного сечения обратного рассеяния</kwd><kwd>озеро Байка</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Baikal omul</kwd><kwd>stock assessment</kwd><kwd>acoustic scattering</kwd><kwd>target strength</kwd><kwd>effective area of cross‐section of backscatter</kwd><kwd>Lake Baikal</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Работа выполнена в рамках государственного задания темы № 0345–2019–0002.</funding-statement></funding-group><funding-group xml:lang="en"><funding-statement>This research was supported by State Project No. 0345–2019–0002.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Кудрявцев В.И., Дегтев А.И., Борисенко Э.С., Мочек А.Д.
