To stop the decline of the European eel population, one of the measures taken is translocating eels for restocking, despite its conservational value being largely unknown. We aimed to contribute to this knowledge gap by (i) investigating the origin of eels caught in coastal waters of Estonia and Finland using otolith microchemistry and (ii) directly estimating restocked eel escapement from Narva River Basin District (NRBD), which is part of the primary Eel Management Unit in Estonia. In Estonia, 74% of the sampled eels (n = 140) were natural recruits and 26% were restocked. In Finland, 27% of the sampled eels (n = 235) were natural recruits and 73% were restocked. Only 1% of all the coastally collected eels were originally restocked to NRBD. These new data together with the reported commercial landings from the escapement route conflict with the current silver eel escapement estimation for NRBD and question the accuracy and value of such indirect calculations compiled for most Eel Management Units throughout the European Union. It is concluded that restocking eels to freshwaters may be futile as a conservation measure in some situations, and better escapement is likely achieved in restocking eels to coastal waters or undammed freshwater systems with a direct connection to the sea.

The article reviewed and analyzed the textbook “Regional Hydrochemistry of Ukraine” (authors V.K. Khilchevskyi, V.I. Osadchyi, S.M. Kurylo), published in 2019. The textbook comprehensively summarizes and covers materials on the hydrochemistry of precipitation, rivers, lakes, reservoirs and ponds, underground and sea waters in Ukraine. The authors used the latest results of studies of the chemical composition of water of various water bodies in the country, applied the hydrochemical characteristics of the river basin districts according to the modern hydrographic zoning of Ukraine (2016), which takes into account the requirements of the European Union Water Framework Directive (WFD 2000/60/EC). A feature of the textbook is that the authors were largely based on the materials of their own studies of the chemical composition of surface waters. They also systematized and generalized the monographic works of leading Ukrainian scientists, in different years (from the 1950s to the present day) they studied fundamental and applied issues of hydrochemistry of surface, underground and sea waters. The structure of the textbook consists of a preface, 11 sections, applications and a list of references. The textbook is intended for students of the specialty “Earth Sciences”, studying in educational programs of hydrological, hydroecological and hydrogeological profile. It may be useful for students of the specialty “Geography”, students in educational programs of a physical-geographical and geo-ecological profile.

The introduction in Ukraine in 2016 of basin integrated principles in the zoning and management of water resources of the state in ccordance with the Directives of the European Union was an extremely relevant and progressive measure. However, when adopting the relevant normative acts and regulations, the iverskodonetsk river basin was unreasonably lowered to the sub-basin of the Don River. Geomorphological and hydrological analysis of geographical maps at a scale of 1:200000-1:500000 of the south-eastern regions of Ukraine and border regions of the Russian Federation allowed to substantiate the basin status of the Siverskyi Donets River, to allocate 17 sub-basins and and their man-made changes, as well as to offer a water monitoring system.

Integrated River Basin Management

PurposeThe purpose of this paper is to examine the European Union (EU) Water Framework Directive. It seeks first to determine whether its provisions align with modern thinking on integrated river basin management and second to assess the degree to which it has the potential to achieve legislative and inter‐agency integration throughout the Union.Design/methodology/approachThis is a desktop study. The paper draws upon theories and definitions of integrated river basin management and internal integration in existing literature and then proceeds to examine the provisions of the Water Framework Directive in the light of the models identified.FindingsThe framework for river basin management in the Water Framework Directive does not fully match the modern approach to integrated river basin management. The directive is limited by its primary focus upon the single medium of water, and its consequent failure to fully address wider land use planning issues. It, therefore, also fails to achieve integration between all relevant legislative instruments. It provides a framework for stakeholder involvement that could potentially serve the goal of inter‐agency integration. However, due to the high level of discretion in the hands of member states, there is likely to be a substantial divergence of practice across the EU.Originality/valueIn assessing the Water Framework Directive against modern notions of river basin management and the directive's stated integrative aspirations, the paper informs implementation and practice in member states.

The article studies the notion of the river basin principle of water resources management, its meaning, its legal definition in the EU directives, the particular aspects of its implementation in Ukraine, and its overall importance in terms of water quality and management of water resources, including the marine environment. It is determined that the river basin principle of water resources management is one of the key matters of the EU environmental policy and is a topical issue for Ukraine in the process of European integration. Essentially, the river basin principle of water resources management is defined as integrated management within a river basin district. It is concluded that this principle is one of the main components of integrated management of water resources and is, in fact, the basis of the integrated approach to such management.

This paper deals with the importance of the spatial, geographic aspect in analyzing ferry traffic, especially on Croatian islands. The importance of ferry traffic is analyzed within the regional development of the European Union as a whole, as well as through some examples from different states. The analytical part of the paper deals with correlation between the ferry traffic and its two most striking indirect consequences that are present on Croatian islands, and those are demographic development and tourism. There is a close, direct connection between ferry traffic and tourism, as well as between ferry traffic and general demographic trends. Since there is no evidence of correlation between the index of seasonal frequency of the ferry lines (direct reflection of tourism) and the index of change in population trends on Croatian islands analyzed in this paper, the conclusion is that tourism, as the main economic activity on Croatian islands, can ease – but not significantly eliminate – depopulation characteristics of the insular part of Croatia.

Reducing diffuse pollution is a perpetuating problem for environmental regulators. This paper will consider novel ways to regulate its impacts on the aquatic environment, with particular reference to rural landuse. It will look at the relationship between science, policy and law, and the contributions of integrated water resources management and governance at regional, national and river basin scales. Regulatory frameworks for water in the European Union will be explored, along with their implementation nationally in Scotland and at catchment scale in the Tweed river basin. It will conclude that regulation has a role to play, but that it is necessary to take a visionary holistic and integrated approach, nesting regulation within a governance framework that involves all stakeholders and takes full account of developing science and socio-economic drivers to meet environmental objectives.

The project summarised in this paper was aimed at developing water quality legislation in Hungary and funded through the PHARE programme of the European Union. Hungary, in common with the other former Eastern European countries, is in a period of transition as it moves from a state socialist system to a free market economy and a full member of the European Union. The project sought to explore the means whereby water quality could be managed on a river basin basis and the legislative, institutional, economic and regulatory challenges resolved. A key element of the project was the carrying out of five case studies, on different catchments, to evaluate the various approaches. An important element of these studies was the participation of all interested parties in the individual catchments. The project showed that to move to a full system of integrated river basin management would be a step too far at this stage and, instead, recommended a system of Catchment Planning Commissions, accountable to Central Government, for the development of catchment based water quality objectives and plans for their achievement together with the monitoring and reporting of progress on implementation. The concomitant legal requirements were detailed and the need for public participation emphasised.
