[Seasonal dynamics of diel changes in inshore benthopelagic communities of the Black Sea by the example of the Golubaya Bay (Gelendzhik Town)].

Seasonal and diel changes in littoral plankton in the Golubaya Bay (near Gelendzhik Town) were studied at seven daily stations from October 1999 to September 2000. In the night-time, the plankton included both holoplanktonic and demersal species rising to the upper layers (benthopelagic plankton). The role of benthopelagic and holoplanktonic organisms in relation to the time of the day, season, and phase of the moon was determined. Benthopelagic plankton of the Golubaya Bay largely included amphipods (which were the most abundant), mysids, isopods, decapods, tanaids, cumaceans, and polychaetes.
