population dynamics, rational fishing, intensity and selectivity of fishing, emissions, regulation of the level of fishing impact, stock-market-fishing system

The article proposed to discuss a concept of new strategy for the sustainable use of populations of aquatic organisms using as an example a fishery for Walleye Pollock in the Far Eastern seas of the Russian Federation. It is shown that the current regulations governing the impact of fishing contained in the Fishing Regulations do not quite consider changes related to the dynamics of pollock populations parameters. As a result, there is an uncontrolled and often negative impact of fishing, which leads to changes in the phenotypic and size-age structure of W. Pollock populations being fished, which ultimately affects the profitability of fishing. It is proposed to develop a separate strategy for each W. Pollock stock unit, which annually regulates the level of fishing impact, depending on the state of the stocks and market conditions. The proposed strategy concept makes it possible to regulate not only the allowable volume of catch, but also the size structure of catches, by changing the fishing parameters every year. It will keep the harvested stocks stable and will help to obtain the maximum possible fishing profitability.

Clusters are the basis for the sustainable development of industrial mariculture in the Russian Federation. Part 1. Trends in the development of world fisheries and aquaculture

The internship topics included familiarization with Japanese resource research, fish processing technologies, and some aspects of aquaculture. The article discusses the conditions that made these internships possible, as well as the change in conditions that led to the completion of this type of Russian-Japanese cooperation in fishing.

Scientific and methodological approaches and experience of breeding Arctic char on the example of factory cultivation of Ladoga palia Salvelinus lepechini (Gmelin 1788)

Based on the long-term experience of keeping Ladoga palia in factory conditions, methodological approaches to the reproduction of this species and a scheme for its cultivation are proposed, which can be used as a basis for breeding Arctic char in fish hatcheries. The characteristics of the object of research and the prospects of its use in aquaculture are given. The features of the development of embryos and larvae are considered. The scheme of formation and operation of repair-brood herds of Ladoga palia is proposed. The criteria for selecting producers for repair and breeding herds are substantiated.

Prospects for the transition of the Russian fisheries complex to the digital economy and the formation of an industry ecosystem

The necessity of accelerated modernization and digitalization of production and management systems of the Rus-sian fishing industry in the concept of its own digital ecosystem is shown. The fishing industry is considered as a concern - a major actor of the national economy, integrated in terms of food production in Industry 4.0 with the transition to Industry 5.0. The vision and mission of the industry, new business models and management systems of production processes and socio-economic systems are conceptually formulated.

Gobies of the Sculpins family (Cottidae) as a promising commercial objects for fishing in the northern part of the Sea of Okhotsk

On the basis of materials collected in 2012-2020, the ecology, the current state of the stock and some features of the biology of gobies of the Sculpins family living in the northern part of the Sea of Okhotsk, as well as the dynamics of their catch, are considered. The prospects for industrial development are shown.

International legal protection of seals

The article gives a brief description of the various species of seals. In the city of Arkhangelsk there is a monument to a seal. Two species of seals live in the coastal waters of Russia: the Steinger seal and the European seal. They are listed in the Red Book. The article analyzes the conventions and agreements on the protection of seals: Convention for the Conservation of Antarctic Seals 1972, the Agreement on the cooperation in research, conservation and management of marine mammals in the North Atlantic 1992, the Agreement between the Government of the USSR and the Government of Norway on Measures to regulate fishing, sealing and protection of seal stocks in the Northeast Atlantic 1957. The decisions of the 51st session of the Joint Norwegian–Russian Fisheries Commission are analyzed. The article ends with an outline of the contribution of the Russian Federation to the rational seal fishery.

Fishing capacity of South Baikal in terms of tourism development and limitations on fishing industry

The article considers eco-economic aspects of using the fishing capacity of the basin of South Baikal in the framework of the development of tourism of the coastal territory within Slyudyansky Municipal District of Irkutsk Oblast and within the entire southern Baikal Region. The article proposes to more strongly focus on developing sport and recreational fishing in this most developed area of Lake Baikal. The eco-economic and legal analysis carried out by the authors allows them to conclude that the traditional regulation of the stock of omul in Baikal by determining the total allowable catches and quotas is not effective enough, since it has led to the prohibition of not only industrial but also limitation of sport and recreational fishing for omul. At the same time, there is no reliable data that recreational fishing along the southern coast of Baikal is the reason for the decrease in the total stocks of omul in Baikal. On the contrary, the South Baikal fishing area can become the basis for a more dynamic development of the tourism industry in the region, including such types of it as cognitive tourism, ecological tourism and sports and recreational one. Moreover, it is the South Baikal fishing area and the coastal territory of Slyudyansky Municipal District that can become a testing site for developing more optimal (considering the specifics of various areas of Lake Baikal) ecological approaches to the regulation, rational use and reproduction of the stock of omul in Baikal for the purposes of sport and recreational fishing at Lake Baikal, as well as development of an environmentally friendly tourism industry in the region. The authors propose to review the strategy of fishery development of the stocks of omul at Lake Baikal and remove restrictions on recreational fishing, accompanying this with organizational and legal measures that allow obtaining reliable statistical data on catches. Precisely in this most economically developed area of Lake Baikal it is advisable to practice the organizational and legal mechanisms for the environmentally friendly development of tourist and recreational activities based on the available water bioresources of the unique lake.

Shipboard tests of tribochemical lubrication mode

The article is devoted to the tests of the main marine engine 8CHRN 32/48 (8NVD-48A-2U) SRT "Captain Rogozin" of the Murmansk SPCRK, operated in the tribochemical lubrication mode in the Barents Sea. The satisfactory condition of the cylinder-piston group parts is shown. Analysis of changes in the physical-chemical parameters of engine oil showed that the tribochemical lubrication mode with the TVM-S device stabilizes the physical-chemical properties of the oil when refilling fresh oil "on the fumes" and ensures continuous operation (up to 10 thousand hours) in a long-term mode equal to two of its resources.

Stock status, environmental factors and reproduction efficiency of the anchovy sprat population (Clupeonella Engrauliformis Borodin) in modern conditions

Until the end of the XX century, anchovy sprat was the leading object of marine fishing in the Caspian Sea. At the beginning of the XXI century, there was a mass death of this species, as well as an outbreak of the number of mnemiopsis comb - a powerful consumer of feed zooplankton. There was a redistribution of keel clusters in the sea. The main part of the fishing stock of keels began to be distributed in the Middle Caspian Sea. The main object of marine fishing has become an ordinary sprat. In recent years (2015-2020), there has been an increase in the number of anchovy sprats. The materials of keel surveys also confirm the annual growth in the number of juvenile sprats. This paper presents the results of recent years of observations, shows the dynamics of the number and biomass of the population, the parent part of the herd, total fertility. The efficiency of spawning and the survival coefficients of the generation in early ontogenesis are shown. Environmental factors that have a direct impact on the formation of the anchovy sprat stock are described.
