Fishing Area

Lake Baikal is the largest fresh water reservoir of our planet and a unique natural site included in the UNESCO World Heritage List. Meanwhile, Baikal is not only Russia’s largest freshwater fishing reservoir. Large-scale commercial fishing started here at the beginning of the 19th century and, with small breaks caused by bans imposed on industrial fishing due to depletion of valuable commercial fishery species stock, continued until October 2017, when once again restrictions in the fishing industry were imposed. One of the reasons for this was the increasing of the illegal unreported and unregulated fishing which led to depletion of harvestable stock of omul. However, these restrictions neither eliminated extensive unreported fishing, nor solved the problem of rapid fish stock rebuilding in the unique lake. Using methods of mathematical analysis and modeling this article examines factors facilitating breach of law in the fishing industry and unreported fishing for Baikal omul. The article provides a brief characteristic of the Baikal oldest Malomorsky fishing area as well as an eco-economic assessment of the possibility to rebuild the fishing stock within this water zone taking into account the increasing tourist flow in the Baikal region.

<p>The current linear use of plastic products follows a take, make and waste process. Commonly used by large scale industries, including the commercial fishing industry, this process results in approximately 8 million tonnes of plastic entering the ocean every year. While the fishing industry supplies livelihoods, a valuable food source and financial capital to millions of people worldwide, it’s also a significant contributor to the ocean plastics crisis. Without effective recycling schemes, an estimated 640,000 tonnes of plastic fishing gear is abandoned, lost or discarded within the ocean every year. New Zealand is no exception to this problem, as China’s waste import ban, as well as a lack of local recycling infrastructures, has resulted in the country’s commercial fishing gear polluting local coastlines as well as islands in the pacific. With the only other option for the plastic fishing gear being landfill, there is a critical need for circular initiatives that upcycle used plastic fishing gear locally into eco-innovative designs.  This research examines the issue by investigating how used buoys, aquaculture ropes and fishing nets from New Zealand’s fishing company ‘Sanford’ may be upcycled into eco-innovative designs through distributed manufacturing technologies. It introduces the idea of the circular economy, where plastic fishing gear can be reused within a technical cycle and explores how 3D printing could be part of the solution as it provides local initiatives, low material and energy usage and customisation. Overall, the research follows the research through design based on design criteria approach. Where materials, designs and systems are created under the refined research criteria, to ensure the plastic fishing gear samples are upcycled effectively into eco-innovative designs through 3D printing.  The tangible outputs of this research demonstrate how a circular upcycling system that uses distributed manufacturing technologies can create eco-innovative designs and provide a responsible disposal scheme for plastic fishing gear. It provides a new and more sustainable waste management scheme that could be applied to a range of plastic waste streams and diverts materials from entering the environment by continuously reusing them within the economy.</p>

Different Levels

There are four main types of economic surpluses that can be achieved when exploiting a fishery. They are rent to the productive nature of the fish stock, normal factor rents to inputs, consumer surplus, and what is called here, worker satisfaction bonus, WSB. The latter refers to nonmonetary benefits individuals can obtain from participating in commercial fishing and, to be complete, in other occupations as well. It is discussed frequently, but has never received any formal treatment in the literature. In this paper the logic behind WSB in the fishing industry is discussed and its implications on policy is shown. A detailed model is developed which can show how all of the components of economic surplus relate to one another and how they will vary at different levels of output.Key words: fisheries economics, economic surplus, worker satisfaction bonus, maximum economic yield

West Of Ireland

This study focuses on the cultural heritage of artisan coastal fishing in the west of Ireland in the 19th century. The town and port of Dingle, County Kerry, offers an important case study on the progress of local development and changing British policies. While there was clearly an abundance of fish, the poverty and the lack of capital for improvements in ports, vessels, gear, education, and transportation, left the fishing industry underdeveloped until well after the 1890s. In addition, a growing rift developed between the traditional farmer-fishermen and the new middle-class capitalist companies. After several royal commissions examined the fishing industry, the leading ichthyologists of the day concluded that an abundance of fish could be taken without fear of overfishing. The utilitarian economic principle became dominant, changing the previous non-interventionist policies. In the end, there was little concern for sustainability. The mismanagement of commercial fishing in the west of Ireland stemmed from a series of factors, including the increasing need for protein in Britain, technological developments that allowed greater fish catch, and the Conservative government’s political policy of ‘constructive unionism’ that attempted to develop the Irish economy to preserve the kingdom.

The present article is based on the review of the current patent, scientific and technical sources. It indicates the main challenges of fishing industry in the North-West Russia with the Murmansk Region taken as an example. The basic fishing techniques, being employed by the local fishing companies, are considered. The article defines the main challenges of the Northern commercial fishing area resources exploration and sustainable use. It substantiates the necessity to increase the share of fishing tools with better selectivity. It is concluded that the raw-materials supply crisis is likely to set in the fish processing industry. The article analyses the existing methods of processing applied to the underutilized fishing grounds. It reveals a correlation between the intensiveness of research applied to specific fishing grounds and the consumer demand availability and scope. It is concluded that predominantly research is made with regard to the use of underutilized species for production of dietary supplements and components which alter some food properties. The article substantiates the necessity to use the non-conventional hydrobiont species for food production, based on the consumer demand data. A study of the main standards has been performed with regard to regulation of the hydrobiont catching issues. The article reviews the underutilized species of the Northern commercial fishing area which are most prospective from the production and processing point of view. It concludes with the prospects of the proposed option for the fishing industry development and its probable impact on the development of coastal infrastructure and of the whole region.

Energy Potential

Exhaustion of traditional energy resources, their uneven geographical location, and catastrophic changes in the environment necessitate the transition to renewable energy resources. Moreover, Ukraine's economy is critically dependent on energy exports, and in some cases, the dependence is not only economic but also political, which in itself poses a threat to national security. One of the ways to solve this problem is the large-scale introduction and use of renewable energy resources, bioenergy in particular. The article summarizes and offers methods for assessing the energy potential of agriculture. In our country, a significant amount of biomass is produced every year, which remains unused. A significant part is disposed of due to incineration, which significantly harms the environment and does not allow earning additional funds. It is investigated that the bioenergy potential of agriculture depends on the geographical distribution and varies in each region of Ukraine. Studies have shown that as of 2019 the smallest share in the total amount of conventional fuel that can be obtained from agricultural waste and products suitable for energy production accounts for Zakarpattya region - 172.5 thousand tons. (0.5% of the total) and Chernivtsi region - 291.3 thousand tons. (0.9%). Poltava region has the greatest potential - 2652.2 thousand tons. (7.8%) and Vinnytsia - 2623.7 thousand tons. (7.7%). It should be noted that the use of the energy potential of biomass in Ukraine can be called unsatisfactory. The share of biomass in the provision of primary energy consumption is very small. For bioenergy to occupy its niche in the general structure of the agro-industrial complex, it is necessary to develop mechanisms for its stimulation. In addition, an effective strategy for the development of the bioenergy sector of agriculture is needed. The article considers the general energy potential of agriculture, its indicative structure. The analysis is also made in terms of areas. In addition, an economic assessment of the possible use of existing potential is identified.

AbstractLake Baikal is inhabited by more than 300 endemic amphipod species, which are narrowly adapted to certain thermal niches due to the high interspecific competition. In contrast, the surrounding freshwater fauna is commonly represented by species with large-scale distribution and high phenotypic thermal plasticity. Here, we investigated the thermal plasticity of the energy metabolism in two closely-related endemic amphipod species from Lake Baikal (Eulimnogammarus verrucosus; stenothermal and Eulimnogammarus cyaneus; eurythermal) and the ubiquitous Holarctic amphipod Gammarus lacustris (eurythermal) by exposure to a summer warming scenario (6–23.6 °C; 0.8 °C d−1). In concert with routine metabolic rates, activities of key metabolic enzymes increased strongly with temperature up to 15 °C in E. verrucosus, whereupon they leveled off (except for lactate dehydrogenase). In contrast, exponential increases were seen in E. cyaneus and G. lacustris throughout the thermal trial (Q10-values: 1.6–3.7). Cytochrome-c-oxidase, lactate dehydrogenase, and 3-hydroxyacyl-CoA dehydrogenase activities were found to be higher in G. lacustris than in E. cyaneus, especially at the highest experimental temperature (23.6 °C). Decreasing gene expression levels revealed some thermal compensation in E. cyaneus but not in G. lacustris. In all species, shifts in enzyme activities favored glycolytic energy generation in the warmth. The congruent temperature-dependencies of enzyme activities and routine metabolism in E. verrucosus indicate a strong feedback-regulation of enzymatic activities by whole organism responses. The species-specific thermal reaction norms reflect the different ecological niches, including the spatial distribution, distinct thermal behavior such as temperature-dependent migration, movement activity, and mating season.

The 19Th Century

Whereas the globalization of medicine since the middle of the 19th century has primarily been approached as the sociopolitical and cultural outcome of imperialism, this article argues that Western big business also played a major role through the worldwide export of standardized medical technologies. It focuses on the expansion of Siemens on the X-ray equipment market in non-Western countries during the first half of the twentieth century. This German multinational enterprise experienced slight growth from the mid-1920s onwards but relied mainly on two markets (Argentina and Brazil). It specialized in providing large-scale equipment to a few urban hospitals and engaged during the 1930s in large-scale hospital development together with local authorities and international organizations in various countries (China, Peru, and Central Africa). However, Siemens had great difficulty in expanding its business to include private doctors and inland outlets, where it faced intense competition from other Western X-ray producers. This paper emphasizes that this shortcoming stemmed from a direct application of the European strategy (high-quality, expensive equipment for hospitals) to non-Western markets, where health systems differed.
