    Description: Data on species composition, abundance and biomass of cystoseira epiphyton in various coastal zones off Crimea (Black Sea) are presented. The material was collected during summer periods of 2013, 2014, and 2015. Altogether, 30 samples were selected at depths of 1, 3 and 5 m in two repetitions. Communities for each studied area were identified. Trophic structure of epiphyton communities is defined.
    Description: Приведены данные по видовому составу, численности и биомассе эпифитона цистозиры в различных районах побережья Крыма (Черное море). Материал собирали в летние сезоны 2013, 2014 и 2015 гг. Отобрано 30 проб на глубинах 1, 3 и 5 м в двух повторностях. Выделены сообщества в каждом исследованном районе. Определена трофическая структура эпифитонных сообществ.

    Description: This paper summarizes our own data on the spatial and temporal distribution of species composition, abundance, biomass and trophic structure of gastropod mollusсs in the shallow-water (0–9 m, mostly up to 5 m in depth) areas along the Black Sea Crimean coast from Karkinit Bay in the northern part of the Crimean Peninsula to Laspi Bay in its South Coast. Over the period spanning from 2001 to 2020, 441 benthic samples were taken at 7 sites in sandy silt biotopes. A total of 31 species was recorded with a maximum (22 species) in Kruglaya (Round) Bay. However, only one species, Bittium reticulatum, was found in all of the investigated areas. The highest abundance (4,243±253 ind./m2) was recorded in the area covering the estuary of Chernaya (Black) River and the head of Sevastopol Bay, and the highest biomass (5.3±0.2 g/m2) was observed in Kazachya (Cossacks) Bay. By these parameters, Hydrobia acuta prevailed. The maximum abundance and biomass of gastropod molluscs in the investigated areas were characteristic of the spring and summer seasons, when the reproduction of the majority of species occurs. The trophic structure of Gastropoda taxocene was very diverse and represented by the following groups: detritivores, scavengers, polyphages, phytophages, predators, ectoparasites, and others (species with unknown type of feeding). In terms of the number of species, phytophages dominated (11 species); detritophages (1,045 ind./m2) dominated in terms of abundance, and scavengers (1.13 g/m2) were dominant by biomass.
    Description: В работе обобщены собственные данные по пространственно-временному распределению видового состава, численности, биомассы и трофической принадлежности брюхоногих моллюсков в мелководной части (0–9 м, в основном до 5 м) акватории Черного моря вдоль побережья п-ва Крым от Каркинитского залива на севере полуострова до бух. Ласпи на Южном берегу Крыма. Всего за период с 2001 по 2020 г. в 7 районах песчано-илистых биотопов была отобрана 441 бентосная проба. В них встречен 31 вид Gastropoda с максимумом (22 вида) в бух. Круглая. Однако только один вид, Bittium reticulatum, обнаружен во всех изучаемых районах. Наибольшая численность (4243±253 экз./м2) отмечена в районе устья р. Черная – вершины Севастопольской бухты, максимальная биомасса составляла 5,3±0,2 г/м2 в бух. Казачья. По этим показателям преобладала Hydrobia acuta. Пик численности и биомассы брюхоногих моллюсков в исследованных акваториях приурочен к весенне-летнему сезону, когда размножается большинство видов. Трофическая структура таксоцена Gastropoda весьма разнообразна и представлена такими группами, как детритофаги, падальщики, полифаги, фитофаги, хищники, эктопаразиты и прочие (виды с неизвестным типом питания). По количеству видов доминируют фитофаги (11 видов), по численности — детритофаги (1045 экз./м2), а по биомассе — падальщики (1,13 г/м2).
