Аннотация: Приводится метод расчёта силовых и геометрических характеристик крыла ставного невода с жёстким каркасом и его элементов: мёртвых якорей, свай и чипчиков. Метод основан на использовании конечных зависимостей, связывающих геометрические и силовые характеристики крыла ставного невода и позволяет: определить давление на сваю; установить глубину забивки свай; подобрать материал свай (гундер); рассчитать натяжение в наклонных оттяжках и подобрать их диаметр и материал; определить необходимое количество свай и оттяжек на крыло./The method allows to calculate force and geometrical characteristics for a wing of set-net with rigid frame and for its elements (dead anchors, piles) in the range. It is based on finite dependences between these characteristics. The following parameters are defined: pressure upon piles; depth of piles; tension in ropes; required number of piles and guys; parameters of seine elements; holding force of anchors necessary for trouble-free operation. Reasoning from these characteristics, the anchors could be selected and optimal materials and diameter for piles and guys could be determined.

Отбор проб проводили сетью Джеди (168 мкм) в слое 100-0 м или дно - 0 м, численность и биомассу рассчитывали с учётом коэффициентов уловистости. Период исследования относился к категории тёплых лет. Видовое богатство зоопланктона в зависимости от сезона варьировало от 26 до 71 таксона./Zooplankton communities were investigated in the Barents Sea in winter (March), spring (May-June), summer (August-September), and autumn (October) of 2007. The zooplankton samples were obtained with a Juday net hauled vertically from the sea bottom or 100 m depth to the sea surface. Abundance and biomass of zooplankton were calculated using the coefficients of catch ability. Species richness of zooplankton varied form 26 to 71 taxa depending on the season.

Аннотация: Рассматривается математическое описание динамики экосистем большого числа видов на основе моделей трофических взаимодействий вольтерровского типа. Специальный вид системы уравнений Лотка-Вольтерра позволил свести систему к матричному дифференциальному уравнению. Будучи матричным обобщением уравнений типа Рикатти, это уравнение интегрируется в квадратурах. Таким образом, было найдено точное аналитическое описание динамики экосистем вольтерровского типа. В заключении обсуждены перспективы использования данного результата для исследования динамических моделей экосистем более общего вида./General principles of ecosystem dynamics are investigated for the purpose of modeling the reaction of a species stock to fishery. The simplest model of trophic net - the system of Lotka-Volterra equations is considered. It is presented in a special form that allows reducing the system to the matrix differential equation. Being a matrix generalization of Ricatti equation, this equation is integrated in quadratures. Thus, the exact analytical description is found for dynamics of Lotka-Volterra type ecosystems. Possibilities to apply the obtained result for other models of dynamic ecosystems are discussed.

Аннотация: The XSA model traditionally used by AFWG for the North-East cod stock assessment is to be considered as only one of great variety of age-structured stock assessment models used for this purpose in the present world, and the model which is not without known important shortcomings. Our results obtained using the TISVPA model, the model aimed at robustness and with attention to generation-dependent peculiarities, may indicate that the XSA-derived results may lead to erroneous perception of the stock and hardly can be regarded as the only and sufficiently reliable basis for further management decisions.

Аннотация: The potencials of the modern analytical approach to assessment of a total allowable catch (TAC) as the key fisheries management measure were demonstrated on the example of the stock of walleye pollock Theragra chalcogramma (Pallas 1814) in the East of the Okhotsk Sea. The database (DB) of the information system (IS) "Fishery" was used as an alternative source of the initial information for analysis. The observed catches per unit effort ware converted into stock abundance indices. The main emphasis was placed on the following methodological issues: standardization of the observed values of catch per unit effort using generalized linear models (GLM), justifying the choice of the base model of the stock dynamics and the harvest control rule (HCR), risk analysis and other diagnostic procedures aimed to improve the efficiency of the aquatic biological resources management.

The most attention is given to aspects of survey stratification, which enables us to obtain more accurate stock abundance estimates, to optimal allocation of samples by strata and necessary sample size. The calculations are made for a number of years.

Аннотация: The regression methods are shown not to allow assessing an open local stock as in the case of the Leslie and De Lury classic models. To solve this problem, a method based on Kalman filter is suggested. Besides, there is given a description of some methodical weak points of De Lury model, which make it less preferable regarding to Leslie's model. This work presents the Leslie's Generalized Model with Kalman filter (LGM KF), which is aimed to reconstruct a stock dynamics during fishery using the temporary series of catches on local areas in the presence of migratory flows and neglected catch.
