The recent data on fish eggs and larvae by species in the South Azores seamounts are presented. Distribution of the commercial fish species – East-Atlantic horse mackerel Trachurus picturatus and eastern mackerel Scomber japonicus – is analyzed in the early ontogenesis. The impact of surface currents upon ichthyoplankton concentration is shown. It is indicated that fish eggs and larvae occurred more frequently and had the higher abundance above seamounts as compared to the adjacent areas. The most diversified species composition and the highest abundance of ichthyoplankton was observed during the seasons considered in the area of seamounts Irving and Meteor. This location is one of the largest in area and is characterized with the most complicated oceanographic parameters.

More then 20 rivers and 50 stations were researched. In all observed rivers was found 32 young fish species. In small rivers structures of species is simple and consist of about 6 species. According structures of species in the small rivers were detected a few potential salmon rivers-Pissa, Putilovka, Angrapa, Lava. The small lowland rivers which fall into lagoons or big lake are the place of spawning for perch and roach. In the middle and big river quantity of species is bigger then in small river. In the big rivers are detected dependence between species and environmental condition.

|Frolkina Zh.A.||Impact of human activities on changes in the ichthyoscene at the South Georgia shelf (Abstract)|
The natural marine ecosystem of the South Georgia area is not adapted to an anthropogenic impact, since human activities can provide a rapid non-reversible reconstruction of this ecosystem. The example of such impact is illustrated by significant capture of notothenia (Notothenia rossii marmorata) in the beginning of the 70s. In the end of the 60s, notothenia occupied the leading positions in the ichthyoscene of this area; therefore the quick reduction of this fish stock provided the huge impact on the ecosystem state and resulted in its full reconstruction. Since the middle of the 70s, icefish (Champsocephalus gunnari) plays the central role in the fish community of the South Georgia area. The ecosystem reconstruction has continued till the end of the 80s.

Analyze of morphometric characteristics of lagoons of the World Ocean was made with use of available in Internet satellite photographs LandSat 7 for period from 2000 till 2011 years. Along shore and cross shore sizes of lagoons don’t exceed 260 and 108 kilometers accordingly. More than 80% of lagoons are stretched along a shore. In average, along shore size is 7 times larger than cross shore one. Significant part of lagoons (35%) have along shore size of 10-25 km, and cross shore size less than 5 km (47%), along shore size doesn’t exceed 50 km for 63% of lagoons, and cross shore size doesn’t exceed 5 km for 75% of lagoons. Squares of a lagoon could rich 18000 km2, and 70% of lagoons have the square less than 100 km2. Nearly one half of lagoons (49.5%) have one inlet, and for 49% of lagoons openness ration is between 0.1-1.0.

It was held investigation of the influence of the boards attack angle on the warp tension and geometrical parameters of the bottom trawl in the Peter the Great Bay (Sea of Japan). Warp tension (resistance to trawl system) was determined using a dynamometer, and the geometric parameters (vertical opening of the trawl and the distance between the boards) - with Norwegian equipment «Scanmar». Different angle of trawl boards attack were asked by varying mounting positions of warp and back strops on the board. As a result, it was determined statistically significant of the nonlinear dependence of the resistance and trawl system geometry from the trawl boards attack angle. And the nature of the experimental curves does not contradict to the theoretical representation of the trawl system mechanics.

|Seslavinskyi V.I.||Trap’s construction, catch selectivity and tactics of grass shrimp at peter’s the great bay (Abstract)|
At Peter’s the Great Bay were held experimental works aimed on studying the effects of changing constructive parameters of the traps and tactical catch methods on the fishing effectiveness of grass shrimp. Represented sized shrimp ranks of several work areas. Resize the holes from 30 to 70 mm, with the measured weight and size composition of the shrimp catch and fish catch. The maximum catch of shrimp was obtained with the size of the holes at 50 mm. With a larger size of holes, a decrease of the catch is observed. The dependence of the catch on the number of holes and their total area is shown. Growth in the catch observed with increasing amount of holes from two to five. Increasing the input area on more than 100 cm2 is accompanied by a decrease in the catch. Increasing traps’ capacity accompanied by improvement of the retaining properties of input devices and respectively, by the catch. It’s suggested to use flexible shrimp traps, which increased volume does not create difficulties in their partition.

Application of bottom trawls leads to degradation in bottom biocenoses of some areas of habitation of a cod and a haddock in Barents sea, to decreasing of a specific biodiversity and the number of sea organisms. In the case of the further restrictions for bottom trawling in the Barents Sea and of other fishing methods and gears, the national fishery practically can stop. During conducting 1surveys it’s necessary to use both bottom and near-bottom trawls in a near-bottom regime because it allows to register all ages classes of a cod and a haddock. The project of a near-bottom trawl with sorting devices for fishing cod and haddock in the Barents Sea has been developed. Technical testing shows its perspectives as a new survey and commercial fishing gear.
