Vasyura O.L.Feeding behavior of young sterlets Acipenserruthenus (Acipenseridae) at pond and basin rearing in artificial conditions (Abstract)
It is shown that the level of information richness of the environment in which the juvenile fish were raised at early stages of ontogenesis is one of the determining factors for the development of the most important adaptive patterns of behavior. Minimal values of fullness index, lower body weight, and shorter length, along with a feeding spectrum strongly differing from that in natural conditions, are characteristics of juvenile fish kept preliminarily in the hatchery. The food of this group of fish is dominated by organisms of epibenthos, which may have been detected by the fish using gustatory and tactile receptors. At the same time, the proportion of infaunal invertebrates, the detection of which is only possible using olfaction and electric reception, is minimal. The prolonged development of juvenile fish under conditions of sensory deprivations leads to inadequate behavioral skills, making the process of conventionally reflective “switching” upon the release of such juvenile fish in the wild more difficult.

Polunina Ju.Ju.The seasonal cycle of zooplankton in the lower Pregolja River flow (Abstract)
109 species and groups of zooplankton recorded in the lower Pregolja River flow in period 1996-2007. The group of Copepoda was predominant in the zooplankton abundance and biomass. The seasonal variation of the zooplankton abundance was characterized by a maximum in July (130 ± 110 thousand ind .m-3), which was formed by the mass development of rotifers. The peak of the zooplankton biomass recorded in August (958 ± 788 mg m-3), where the main contribution belonged planktonic crustaceans (Clsadocera, Copepoda). The high volume of zooplankton biomass depended on the crustaceans Eurytemora affinis and Acartia spp. from the Vistula Lagoon in autumn. These crustaceans appeared in the River with surge from Vistula Lagoon.

Markyanova M.F.Species structure of chironomidtaxocenosis in the Vistula Lagoon (Abstract)
The Vistula Lagoon, excluding its littoral zone, is inhabited by four chironomid species only: Procladius ferrugineus, Microchironomus tener, Chironomus balatonicus, Cryptochironomus defectus. Species structure of taxocenosis is follows: the dominant species – C. balatonicus (80%); subdominant species – P. ferrugineus (17%), accompanying species – M. tener (2%), C. defectus (1%). Taxocenosis structure by trophic guilds is follows: filter-feeders (C. balatonicus, M. tener) – 82%; predators-grabbers (P. ferrugineus, C. defectus) – 18%.

Shibaev S.V., Sokolov A.V., Anuryeva A.S., Novozhilov O.A., Luneva E.V.Biological parameters of smelt in Neman River during spawning period in 2011-2013 (Abstract)
The article provides the main structural-biological parameters of smelt in Neman River during spawning period in 2011-2013. Duration of spawning period in downstream of Neman River (4-10 km from estuary) is nearby 20-30 days, duration of mass migration is nearby 10 days. Time of the first entrance of smelt in the river influences on population parameters of spawning smelt. Earlier entrance of smelt in the river promotes higher catches of smelt and longer spawning migration.

Navrotskaya S.E., Chubarenko B.V.Climate trends of sea water level near the shore of Kaliningrad oblast (Abstract)
In this work the variations of mean annual water levels were obtained by data from the long-term observations at the hydroposts Pionerskiy (Baltic Sea), Baltiysk (Vistula Lagoon) and Klaipeda (Curonian Lagoon), a steady positive linear trends were found, their size changes depending on the examined period. On the whole, rates of growth of mean water level for the last 100 years in lagoons and sea (1.3-1.8 mm/year) near to growth of water level of the World Ocean for the same period. Speed-up growth of water level in lagoons, leaving growth of level of the World Ocean, is observed from the 2th half of XX century – to 3.2-3.6 mm/year (1960-2003), and especially in his end - to 4.2-11.7 mm/year (1993-2003). It is show of the increasing influence of regional klimatic factors, determining the regime of winds and precipitations in a catchment.

Ezhova E.E., Kocheshkova O.V.Distribution and seasonal dynamics of macrozoobenthos density and biomass in the lower and middle reach of the Pregolya River (Abstract)
It was shown, distribution of species richness along the river reach is uneven. In direction to the river mouth substantial impoverishment of species composition occurs. Oligochaets contribute most part to a total density of zoobenthos along the whole studied part of the river. Bivalves, mostly species of Unio, Dreissena, Viviparus and Valvata genera, also several limneid, sfereid and pisidiid species contribute 50-97% of the total biomass, depending on biotope and the part of the river reach. Seasonal course of benthos density and biomass changing is rather different in the different parts of the river reach. Differences were defined by a life cycle peculiarities of benthobionts, inhabiting the area, wind-surging currents and by a presence of oxygen deficient zones, typical for second part of summer.

Lange E.K.Evaluation of phytoplankton productivity in the lower reach of Pregolya River (Abstract)
The current status of late summer phytoplankton community of the lower reaches of the Pregolya (Kaliningrad Oblast) has been made. In 2011, potentially toxic cyanobacteria Planktothrix agardhii and genus Microcystis dominated in phytoplankton along with diatoms and algae cryptophytes. This fact has not been registered before. Quantitative development of microalgae at the present stage as compared with the end of the 1990 season decreased by 4 times, which could be the result of reducing the load of nutrients (nitrogen, phosphorus) on the Pregolya ecosystem. At the end of the 1990s primary production of phytoplankton of the Pregolya River upstream of Kaliningrad was 800 kcal/m2/year and corresponded to the upper boundary of mesotrophic level.

Shumak V.V.Modeling of growth of the fingerling of the breeding carp (Abstract)
Growth of fingerlings of a breeding carp in 2012, SPS "Izobelino", the Minsk region, Republic of Belarus was studied. The new formula of calculations of growth on the technological periods, according to control catch is applied. And also, the formula of calculation of coefficient of decrease in level of exchange processes depending on temperature of the environment of cultivation is developed and applied. Cultivation of a breeding fingerling of a carp on the basis of strictly control and observance of technology of cultivation locates. Potential of the maximum value of average weight of a fingerling carp in the 2nd zone of fish breeding corresponded 60 g and more. Average weight of fingerling of carp must to achievement of 165 g at cultivation in the conditions of ensuring comfortable values of temperature.

Gouschin O.A., Kulakova V.V., Stont Zh.I.Meteorological monitoring wind numerical modeling and transfer impurities in the atmosphere (Abstract)
Wind is the important component of meteorological supervision of ecological monitoring of sea oil extracting. Use of data AHMS, established directly on an oil-extracting platform, at the analysis of meteorological parameters enables to receive new representations about variability of a wind per 2006-2012. Distinctions between coastal and sea measurements of a wind, both in a direction, and on speed are shown. Characteristics of a wind are used for numerical modeling of the transport of substances in an atmosphere. The model is under construction on the basis of the decision of the advective diffusion equation. The finite elements method was applied to the decision. Dependence of the decision on parameters of advection and diffusion is illustrated.
