ДИНАМИКА СОСТОЯНИЯ ЖЕЛЕТЕЛОГО МАКРОПЛАНКТОНА У БЕРЕГОВ КРЫМА В 1995-1999 гг.

Описано соотношение видов и количественное распределение желетелого макропланктона у берегов Крыма весной 1999 г. в сравнении с аналогичным периодом 1995 г. Отмечается увеличение доли аурелии и плеуробрахии при одновременно резком снижении относительной биомассы мнемиопсиса на фоне заметного уменьшения общей биомассы желетелых.

Gelatinous macroplancton (structure and quantitative distribution) in Crimean coastal waters is compared as found in spring 1995 and in spring 1999. In spring 1999 the gelatinous macroplancton comprised 2 medusae and 2 ctenophores. Revailing species were the medusa, Aurelia aurita and the ctenophores, Mnemiopsis leidyi and Pleurobrachia pileus. A. aurita dominated (81,6%), the portion contributed by the two ctenophores was considerable only in the open sea. Quantitative distribution of the gelatinous macroplancton varied from 0,7 to 1537 g m-2. High biomass was measured near the western coast of the Crimea (Sevastopol and Tarkhankut), minimums were found near the southern coast. In comparison with spring 1995, the composition of macroplanctonic community has changed significanthy owing to increased share A. aurita and P. pileus coupled with simultaneous drop in relative biomass of M. leidyi and the reduction of gelatinous macroplancton total biomass.
