“…2002a and case‐studies therin). It has to be kept in mind that provision of even the best mitigation measures (such as careful evaluated stocking programmes) can never fully compensate for losses of function or structure (Lucas and Marmulla 2000). Habitat improvement is the most desirable option because it should lead to long‐term sustainable improvement with minimal deleterious ecological impact (Cowx 1994a,b, 2002a).…”

“…For inland fisheries managers, socioeconomic aspects of mitigation and rehabilitation (including finance) are currently a more problematic feature than technical aspects, and present one of the greatest challenges to development and maintenance of inland fisheries and aquatic ecosystems (Lucas and Marmulla 2000). This calls for thorough socioeconomic evaluation of inland (especially recreational) fisheries (e.g.…”

“…Reasons may include fish species diversity being more dependent on rehabilitation of habitat structure and maintenance of lateral and longitudinal connectivity than on improvement of water quality (e.g. Lucas and Marmulla 2000; Wolter 2001; Collares‐Pereira et al . 2002a).…”

Reconciling traditional inland fisheries management and sustainability in industrialized countries, with emphasis on Europe

2002

In northern industrialized countries, the inland fisheries sector has long been dominated by recreational fisheries, which normally exploit fish for leisure or subsistence and provide many (poorly investigated) benefits to society. Various factors constrain the development and existence of inland fisheries, such as local user conflicts, low social priority and inadequate research and funding. In many cases, however, degradation of the environment and loss of aquatic habitat are the predominant concerns for the sustainability of inland fisheries. The need for concerted effort to prevent and reduce environmental degradation, as well as conservation of freshwater fish and fisheries as renewable common pool resources or entities in their own right is the greatest challenge facing sustainable development of inland waters. In inland fisheries management, the declining quality of the aquatic environment coupled with long‐term inadequate and often inappropriate fisheries management has led to an emphasis on enhancement practices, such as stocking, to mitigate anthropogenic stress. However, this is not always the most appropriate management approach. Therefore, there is an urgent need to alter many traditional inland fisheries management practices and systems to focus on sustainable development. This paper reviews the literature regarding the inputs needed for sustainability of inland fisheries in industrialized countries. To understand better the problems facing sustainable inland fisheries management, the inland fisheries environment, its benefits, negative impacts and constraints, as well as historical management, paradigms, trends and current practices are described. Major philosophical shifts, challenges and promising integrated management approaches are envisaged in a holistic framework. The following are considered key elements for sustainable development of inland fisheries: communication, information dissemination, education, institutional restructuring, marketing outreach, management plans, decision analysis, socioeconomic evaluation and research into the human dimension, in addition to traditional biological and ecological sciences. If these inputs are integrated with traditional fisheries management practices, the prospects for sustainability in the inland fisheries will be enhanced.

“…Consistent availability of natural habitats suitable for reproduction and recruitment is therefore essential in maintaining sustainable populations (Gibson, 1994). A variety of human activities have however facilitated habitat degradation and destruction, threatening population sustainability of many species in aquatic and terrestrial systems (Lucas and Marmulla, 2000). Understanding underlying mechanisms driving environment-life history trait relationships for populations under environmental stress is thus becoming increasingly important for conservation and management in these systems (Hampe and Petit, 2005).…”

“…In inland waters where there are many human activities, fish migrations in a disrupted fluvial continuum are endangered by construction of dams, weirs, and other migration barriers (Cowx & Welcomme, 1998;Peter, 1998;Lucas & Marmulla, 2000). During downstream migrations, fish risk entering intakes of technologically utilized water (power generation, drinking water, agriculture), which negatively affect their migratory pathway (Jungwirth, 1998;Northcote, 1998;Williams, 1998;Larinier & Travade, 2002).…”

Rotation screen prevents fish damage in hydroelectric power stations

et al. 2008

Downstream migrations of fish over a rotation screen were studied at a hydroelectric power station in Hadamar/Hessen, Germany. This study monitored and evaluated the functionality and efficiency of the rotation screen in order to prevent fish from entering the Kaplan turbine. During one autumn and two spring tests, a total of 1,629 specimens representing 25 species including eel and salmon smolt migrated over the screen. The smallest fish (dace, bleak, three-spined stickleback, and perch) from standard lengths B30 mm were carried by scoop buckets mounted on the rotation screen. The tests confirmed in all cases that the migration activity of fish depended unambiguously on the diurnal cycle (P \ 0.05).
