Description
Summary:This work considers specific features of development and spatial distribution of the animal plankton in the coastal waters of the Black Sea encompassing the areas along the Crimean Peninsula and in the northeastern part of the sea. Zooplankton community was predominantly comprised of the live feed organisms, which distribution across this areas was extremely irregular. The lowest and the highest values of the biomass and abundance of live feed plankton were recorded in the northeastern part of the sea. In the area around the Crimean Peninsula, their distribution was more uniform. The highest level of development was recorded for the representatives of the summer and autumn range of species, with Oithona davisae and Penilia avirostris as the dominant species, which prevalence is characteristic for these seasons. Sea sparkle Noctiluca scintillans was poorly developed throughout the entire investigated area. In higher numbers, this species was presented in the coastal waters of the Crimean Peninsula. The coastal waters of the Northeastern Black Sea were characterized by the highest species diversity. В работе рассматриваются особенности развития и пространственного распределения животного планктона прибрежной зоны Черного моря, охватывающей акватории Крымского полуострова и северо-восточной части моря. Зоопланктонное сообщество в подавляющем своем большинстве формировалось кормовыми организмами, распределение которых по акватории было крайне неравномерным. Наиболее низкие и максимально высокие значения численности и биомассы кормового планктона отмечались в северо-восточной части моря. На акватории Крымского полуострова их распределение было более равномерным. Наибольший уровень развития отмечался у представителей летне-осеннего комплекса с обычными для этого сезона видами-доминантами Oithona davisae и Penilia avirostris. Ночесветка Noctiluca scintillans на всей исследованной акватории развивалась слабо. Более массово этот вид был представлен на побережье Крымского полуострова. Наибольшим видовым разнообразием ...
