In order to reduce the influence of anthropogenic factors on natural resources for several years carried out monitoring studies of water and biological resources. As objects of study were selected fish the Baltic and Barents Seas, the North-East and South-East Atlantic, Southeast Pacific and the fish hatchery. Based on the criteria for identification of studies, the following characteristics: toxic elements, organ chlorine pesticides, polychlorinated biphenyls. For the above identification criteria can be carried out conformity assessment EBE requirements of technical regulations and recommend to the data for the issuance of the certificate of the fishing area.

Based on analysis of the material collected in October-December 2002 and January 2003 in the South-East Pacific, features the peculiarities of the food horse mackerel and mackerel in the overall scheme of their life cycles, identify the place of these species in the food chain. In the oceanic zone in the spectrum of the food horse mackerel and mackerel there are various invertebrates and fish, but the biomass of both species is formed primarily by three groups of crustaceans: Copepoda, Euphausiacea, Decapoda.

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.

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.

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.

|Volodina A.A., Gerb M.A.||Macrophytes of the seacoast of the South-Eastern part of the Baltic Sea (Abstract)|
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.

On materials monitoring supervision under the program "Baltic" speeds of an exchange by oxygen under J.I. Ljahina's formula were estimated. Calculations were spent on 6 basis stations (two in a gulf, two rivers in a mouth and two in the river in city boundaries) with 1996 for 2003 during the periods of absence of ice. The job purpose: working off of methods and recommendations about improvement of an ecological situation in investigated area. The research problem: to reveal existential dynamics of an ecological status of system the river-gulf. Causes and effects of deterioration of an ecological status in system the river Pregolja - the Vistula Lagoon are discussed. The analysis of dynamics of speeds of an oxygen stream has allowed to draw a conclusion that the ecological situation essentially worsens in a direction from the Vistula Lagoon to the river Pregolja. Need to spend cleaning jobs in areas of redeepenings of river Pregolja bed as source of secondary pollution of the river and all system «informed water water areas».

In the department of industrial fishing the empirical formula of static friction μst that enables the calculation under different physical conditions (material and geometric parameters of the drums and the TCR, actual humidity Wf TCR, circumferential speed on the drum Vb; nominal pressure p, the central arc angle of coverage α). The experimental work and on the results calculated static friction coefficients tribopairs formed of fishing threads, cords and ropes (TCR) and traction drums with wedging profile and the pressure roller. For traction drums wedging profile and nylon TCR dependences static coefficient of friction on the ratio of the stress in the incident and trailing branches TCR S1max/S2, wedge angle β traction drum and actual humidity TCR μstWf = ƒ (S1max/S2, β, Wf). For traction drums with nylon rollers and KVI dependences of the static coefficient of friction on the angle of pressing roller μst = ƒ (αpr).

|Shehovtsev L.N.||Approaches to modeling of multifactorial catching systems (Abstract)|
In article the system approach to modelling of multifactorial catching systems of extraction of fish is offered. The system approach consists that it is offered to project tools лова is not isolated, and in system «a vessel - the tool fishing - object fishing - means of operating influence for object fishing». On the basis of formulated before the concept in which J. Kornai and G.B.Klejnera's paradigm is used, the parametres of catching system set by spatial borders and duration of functioning of system are defined. The variant of multifactorial modelling of the catching system which criterion function is the volume вылова for a trade cycle is offered. As factors parametres of tools fishing, a trade vessel, environment, including behavioural aspects of objects fishing, operating influences on object fishing (influence physical influence) are considered. As the basic example the matrix model of fishing systems with passive and active tools fishing, the using light sources located onboard a vessel and on the tool fishing is considered.
