Assessment of seasonal variations at the stages of production and destruction succession in the microplankton off the Crimean Coast and deep waters of the Northern Black Sea on the basis of ATP and chlorophyll α analysis
Based on the data collected during scientific expeditions of RV “Professor Vodyanitsky” in January, April, October 2016 and July 2017, spatial and temporal changes in distribution of microplankton ATP and chlorophyll α as indicators of metabolically active biomass and its photoautotrophic part, respectively, were analyzed. The heterotrophic-photoautotrophic index (HPI) was calculated from ratios of these biochemical parameters and used to assess the stages of production and destruction succession of microplankton community over these seasons. In the investigated area, the sites, which most often demonstrate sharp differences in biochemical parameters of microplankton from the general background, can be considered anomalous and subjected to anthropogenic impact, mainly associated with household and industrial effluents. In general, upon comparison of the distribution of the metabolically active biomass and its production part in the specified seasons the similarity in the values manifested itself in the shallow coastal waters of Crimea: low values for the waters near the western part of the peninsula were assessed to be oligo-mesotrophic; increased values for the waters adjacent to the Kerch Strait in the east were found to be meso-eutrophic. Based on the HPI values, the situation, most promising in terms of development of microplankton biomass and increase in water productivity was observed in the investigated area in autumn. Quite possibly, it is one of the key factors affecting seasonal migration of some fish species from the Azov Sea to the Black Sea in the autumn-winter season.

Based on the data collected during scientific expeditions of RV “Professor Vodyanitsky” in January, April, October 2016 and July 2017, spatial and temporal changes in distribution of microplankton ATP and
chlorophyll α as indicators of metabolically active biomass and its photoautotrophic part, respectively, were analyzed. The heterotrophic-photoautotrophic index (HPI) was calculated from ratios of these biochemical parameters and used to assess the stages of production and destruction succession of microplankton community over these seasons. In the investigated area, the sites, which most often demonstrate sharp differences in biochemical parameters of microplankton from the general background, can be considered anomalous and subjected to anthropogenic impact, mainly associated with household and industrial effluents. In general, upon comparison of the distribution of the metabolically active biomass and its production part in the specified seasons the similarity in the values manifested itself in the shallow coastal waters of Crimea: low values for the waters near the western part of the peninsula were assessed to be oligo-mesotrophic; increased values for the waters adjacent to the Kerch Strait in the east were found to be meso-eutrophic. Based on the HPI values, the situation, most promising in terms of development of microplankton biomass and increase in water productivity was observed in the investigated area in autumn. Quite possibly, it is one of the key factors affecting seasonal migration of
some fish species from the Azov Sea to the Black Sea in the autumn-winter season. |

На основе данных, полученных в научных экспедиционных рейсах НИС «Профессор Водяницкий» в январе, апреле, октябре 2016 г. и в июле 2017 г., проанализированы пространственно-временные изменения распределения АТФ и хлорофилла α микропланктона как показатели общей метаболически активной биомассы сообщества и фотоавтотрофной его части, соответственно. Из соотношений концентраций этих биохимических показателей рассчитан гетеротрофно-фотоавтотрофный индекс (HPI), который использован для оценки стадий продукционно-деструкционной сукцессии сообщества в указанные сезоны. Участки исследованных акваторий, на которых наиболее часто отражаются резкие отличия биохимических показателей микропланктона от общего фона, можно принять во внимание как аномальные, подверженные антропогенному воздействию, главным образом связанные с бытовыми и промышленными стоками. В целом в порядке сравнения распределения метаболически активной биомассы и продукционной его части в указанные сезоны сходство величин проявилось в прибрежном мелководье Крыма: низкие — с оценкой олиго-мезотрофные — у западной части полуострова, повышенные — с оценкой мезо-эвтрофные — у восточной, в водах, прилегающих к Керченскому проливу. Судя по величинам НРI, в исследованных водах наиболее перспективная ситуация к развитию биомассы микропланктона и повышению продуктивности вод была отмечена в осенний сезон. Вероятно, это является одним из ключевых факторов сезонной миграции некоторых видов рыб из Азовского моря в Черное в осенне-зимний сезон.
