“…Evidence is growing that these principles are not easily implemented in practice. Although progress has been made, cases from Norway, Australia, US, Canada, Philippines, Japan, China and the European Union (Rodriguez, 2017;Giebels et al, 2016;Kirkman, 2013;Garces et al, 2013;Furukawa, 2013;Huang et al, 2013;Peng et al, 2013) show that problems remain when establishing holistic management regimes and when gaining holistic knowledge. Often, mono-disciplinary perspectives dominate the knowledge production and utilization process -such as in environmental impact assessments -evidencing difficulties in combining social and ecological approaches.…”

The Water Framework Directive (article 2, paragraph 21) as well as the Marine Strategy Framework Directive (MSFD, Descriptor 4) stress the need for assessing the quality of the structure and the functioning of ecosystems. The MSFD also underlines the urgent need for development, testing, and validation of ecosystem state indicators. Holistic function-based criteria and indicators as provided by Ecological Network Analysis (ENA) could be used to define and assess the 'Good Environmental Status' of marine ecosystems. This approach also feeds Ecosystem Based Management (EBM). ENA generally analyses the fluxes' quality of a single medium such as here the carbon fluxes in a food web and produces a number of useful metrics that indicate, inter alia, the total carbon flow through the system, the quality of the functioning of the system or the trophic efficiency of system. A short list of indices [i.e. Detritivory over Herbivory ratio (D/H), Connectance Index (CI), Transfer Efficiency (TE) over trophic levels, System Omnivory Index (SOI), Finn's Cycling Index (FCI), relative Redundancy (R/DC), Average Mutual Information (AMI) and Interaction Strength (IS)] is proposed for practical use. This paper presents a first framework for OSPAR Regional Sea Convention food web indicators based on ENA. These are presented here focusing on their applicability and what is needed for implementation, illustrating their potential use by case studies.

“…Restored habitats do not always contain similar fish communities to adjacent natural habitats [68]. However, in the context of urban environments, conserving habitats is not always an option, because in many cases the removal or change to these habitats commenced decades or even centuries ago [69]. The benefits of "good" restoration in support of urban recreational fisheries can extend to aquatic health in general.…”

Abstract:Recreational fishing is an important wildlife harvesting activity in urban coastal areas, and recreational harvest in these areas can frequently exceed the commercial harvest. Recreational fishing is a key way that many members of the public experience the environment. The activity enhances social capital, promotes respect for nature, provides health benefits and can provide economic benefits to coastal communities. It is also an important driver of the science on aquatic animals and habitats, and an important tangible reason for many members of the public to conserve and protect aquatic resources. Overall, there has been little specific consideration of urban recreational fisheries management in Australia, despite the paramount importance of urban areas as a focus of recreational fishing activity. This paper identifies that in order to maximize individual and societal benefits from recreational fishing, there needs to be a refocussing of management with the aim of being more holistic. Historically, fisheries management in Australia has focused on maximum sustainable yield (MSY) or maximum economic yield (MEY) which is relevant for the commercial fishing sector, but neither of these is directly relevant to recreational fisheries. This paper identifies that Urban Fisheries Management Plans are required that recognize the specific issues associated with urban recreational fisheries. These plans need to coordinate within and between levels of government and have clear management objectives relevant to urban recreational fisheries. Enhanced opportunities for meaningful citizen science can be incorporated at multiple levels within these plans and this can engender public support for environmental stewardship, as well as fill a very important gap in the knowledge base necessary for managing the activity. As urban recreational fisheries are often occurring in highly modified or degraded habitats, a central element of these plans needs to be habitat restoration and this can have broader benefits for aquatic health. Other management tools include habitat creation (e.g., artificial reefs), optimization of coastal infrastructure as fisheries habitat, and stock enhancement. Overall, Urban Fisheries Management Plans represent a necessary evolution of fisheries management to better address the specific challenges of urban recreational fisheries management, and to best ensure that benefits are optimised.

“…This is primarily due to the Restoration programs, if applied as they are designed, have shown themselves to be productive for achieving their objectives (Jenkinson et al, 2006;Rydgren et al, 2013;Wortley et al, 2013). Projects in Europe and North America have all shown successful results at the preliminary stages, in the first 5 to 10 years of the restoration program (Furukawa, 2013;Gumiero et al, 2013), if the restoration management plan has been followed. One major issue with restoration programs is the long-term projections of the restoration programs, which are usually not reached or assessed.…”

Restoration is the process of reducing or reversing damage to an ecosystem so that it can function in its original manner. However, many restoration programs do not achieve this. In the Nakdong Estuary, the largest migratory nesting site in the center of the East Asian-Australasian flyway, an estuarine barrage was constructed in the 1980s that required site restoration following its completion in 1987 and the expansion of several large industrial complexes(Noksan and Jangrim) and a residential development(Myeongji). The goal of the restoration was to restore the function of the wetland to its pre-disturbance state. To achieve this, a restoration program was designed consisting of three stages. The first stage (1993)(1994)(1995), saw the construction of three artificial wetlands(Shinhori, Daemadeung, and Eulsuk), the second (2003)(2004)(2005) involved the dredging and returning of farmed lands to their natural state, and the third(2008-2012) focused on the rehabilitation and vegetation development of the wetlands. However, the project has not achieved all of the desired goals, and it is an example of the lapses in ecological restoration following anthropogenic disturbance. Issues that resulted in an incomplete restoration included the timing of the stages, noncompliance with the restoration plan, not directly monitoring the restoration or continuing the monitoring following completion of the development project, and the political subversion of the restoration plan. For the success of the restoration plan, it is necessary to avoid mistakes such as inconsistent monitoring, unequal levels of stakeholder involvement, and political interference.
