Низкая эффективность большинства характеристик биоты обусловлена тремя основными причинами: недостаточное для корректных вычислений число видов в пробе, что нередко встречается в акваториях, подверженных заметному антропогенному стрессу; существенное влияние сезонной и межгодовой изменчивости, исключить которое часто не представляется возможным; трудности видовой идентификации молоди множества гидробионтов, что ведет к неоправданному увеличению или уменьшению значений большинства биотических параметров.</p></abstract><trans-abstract xml:lang="en"><p>There is shown using the two-factor covariation analysis ANCOVA that, from the position of statistics, TPFbio is the only truly suitable index for monitoring and assessment the ecological state of the marine environment, whereas the indices AMBI, M-AMBI and BOPA should be considered as limited suitable and the others as unsuitable. Poor efficiency for the most of biota characteristics has the following three main reasons. Firstly, the number of species in samples from the areas subjected to anthropogenic stress is usually insufficient for correct calculations. Secondly, the influence of seasonal and interannual variability is usually significant and cannot be excluded. Thirdly, accurate taxonomic identification is difficult for juveniles of many species that can lead to unjustified under- or overestimation of many biotic parameters.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>экологическое состояние</kwd><kwd>загрязнение</kwd><kwd>эвтрофикация</kwd><kwd>донные отложения</kwd><kwd>залив Петра Великого</kwd><kwd>экологические индексы</kwd><kwd>характеристики обилия</kwd><kwd>ковариационный анализ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ecological state</kwd><kwd>contamination</kwd><kwd>eutrophication</kwd><kwd>bottom sediments</kwd><kwd>Peter the Great Bay</kwd><kwd>ecological index</kwd><kwd>abundance characteristics</kwd><kwd>ANCOVA</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Автор благодарен сотрудникам ДВНИГМИ Т.А.
