Lange E.K.Phytoplankton complex in the Russian part of the Curonian Lagoon (2001-2007) (Abstract)
In 2001-2007 the late summer phytoplankton in Russian part of the Curonian Lagoon was studied. During this period the dominant complex of phytoplankton included no more than 10 species of microalgae. In 2001 and especially in 2002, vegetation level of cyanobacteria Aphanizomenonflos-aquae was traditional high, when the phytoplankton biomass exceeded 1000 g/m3. In 2003–2007 zones of predominant by indicators of eutrophic conditions were in water area – potentially toxic cyanobacteria Planktothrixagardhii (especially in 2007) and diatom Actinocyclusnormanii (starting from 2004). In 2003–2007 the abundance of summer phytoplankton has decreased compared to those in 2001–2002.

Ezhova E.E., Kocheshkova O.V.Some tendencies of macrozoobenthos changes in the Vistula Lagoon, Baltic Sea, 1997-2001 (Abstract)
Results of AB IORAS monitoring studies in the Vistula Lagoon, 1997-2011 on macrozoobenthos are generalized. It was shown, total benthic biomass has been significantly decreasing from the beginning of 2000s. Dynamics of benthic biomass was defined mostly by dynamic of Marenzellerianeglecta,, a role of which has been gradually decreasing during last decade. Positive correlation between biomass and temperature was revealed for oligochaetes and hydrobiids, and the negative one for polychaetes. Such kind of dependence coincides well with eco-physiological requirements and geographical origin of the mass species of the lagoon benthos. A prominent change of benthocenosis structure was marked: polychaetes lost a dominance, bivalves become a prevailing group for 15-years period.

Gerasimov Yu.V., Vasyura O.L.Growth and feeding characteristics of young sterletsAcipenserruthenus (Acipenseridae) in a pond depending on the duration of their initial tank keeping (Abstract)
The young sterlets obtained from artificial spawning in 2010 and 2011 were maintained under similar hatchery conditions in standard plastic tanks. Three groups of fry were transferred from the tanks into a pond in a month, two and three months after hatching, respectively. During the pond keeping, the fish were regularly sampled; their length, mass and gut content were analyzed. The fry released into the pond in a month after hatching displayed faster weight and linear growth, as well as better qualitative and quantitative feeding characteristics, compared to later released fry.

Esiukova E.E., Chubarenko B.V., Leitsina L.V., Bebieva J.S.Influence of typical wind forcing on the peculiarity of circulation regimes in Vistula Lagoon: results of numerical modeling (Abstract)
Three-dimensional hydrodynamic model MIKE3-FlowModel (DHI Water & Environment, http://www.dhi.dk) was used to study the peculiarities of circulation regimes in the Vistula Lagoon (Baltic Sea), corresponding to the characteristic wind load conditions, for the determination of the circulation zones and stream-like motion. The structure of flow fields in the pool at 9 levels (surface horizon 0,25m, the depth of 0,75 m, 1,25, 1,75, 2,25, 2,75, 3,25, 3,75, 4,25) and 14 vertical sections for different wind loads were analyzed. As a result, on the example of the Vistula Lagoon the Baltic Sea, it was determined that in the area of the shallow-water coastal lagoon, there are specific areas where the regime of circulation or stream-like motion of water exist at most cases of the wind load. These zones are associated with the bathymetric structure and the geometry of the boundary and, most importantly, there is a correspondence between the hydrodynamically defined zones and the actual distribution of fine material at the bottom of the lagoon.

Flora of marine macrophytes (data 2006-2012) consists of 32 macroalgae species. Annual green algae are dominate in shallow depth (0-3m), being represented first of all by Cladophoraglomerata, Ulvaprolifera and Ulvaintestinalis. Red algae except Polysiphoniafucoides and Ceramiumtenuicorne, are rare and not abundant. Red algae Furcellarialumbricalis and Polysiphoniafucoides dominate among the perennial algae by biomass at depth 3-6 m, but locally, at hard substrates only. In 2010-2011 the decrease of depth distribution of pereninialFurcellarialumbricalis and Coccotylustruncatus was shown.
