Book (series)Consequences of biomanipulation for fish and fisheries 2001
Also available in:
No results found.The main goal of biomanipulation by fish reduction is not a change in the fish community but a change in the aquatic ecosystem. Fish reduction is a method to push the system in another state, usually a shift from algae domination to macrophyte domination. Intensive fish removal is done by one of the following methods: seining (the Netherlands, Germany, UK), trawling (Sweden, Finland), use of rotenone (Norway, USA, Poland) and stocking of piscivorous fish (USA, Germany). If circumstances allow it (reservoir, ponds) draining is combined with seining (the Netherlands, UK, Poland). The intensity and duration of fishing differs per case, but is quite important for the way the system changes. Fishing may be combined with stocking of predatory fish, mainly pike and pikeperch (or walleye)...... -
Book (series)Ecosystem approach to fisheries in South and Southeast Asia
Lessons from marine capture fisheries
2025Also available in:
No results found.The ecosystem approach to fisheries (EAF) has been widely promoted as a framework for fisheries management, integrating ecological, social and governance dimensions. This publication compiles ten case studies of diverse fisheries from South and Southeast Asia to showcase ongoing efforts to manage fisheries under EAF principles and synthesize lessons learned from its implementation in the region. The findings highlight several key factors driving the transition to EAF, including ecological crises such as stock depletion and habitat loss, socioeconomic challenges like declining fisher incomes, and governance reforms promoting co-management and stakeholder participation. Enabling conditions – such as strong community leadership, regional policy support, and financial incentives – have facilitated EAF adoption. However, persistent barriers – such as weak enforcement, limited scientific data, and socioeconomic pressures – continue to hinder long-term sustainability. EAF implementation faces compounding challenges, particularly in socioeconomically depressed, resource-dependent communities, where environmental and economic vulnerabilities create self-reinforcing cycles. While EAF adoption has grown globally, its partial success often stems from localized, species-specific efforts that fail to address broader ecological complexities and cross-scale environmental stressors. Sustainable financing remains a critical barrier to full implementation. For long-term success, EAF must be embedded within a comprehensive, multi-scale governance framework that aligns ecological sustainability with socioeconomic resilience. -
Book (stand-alone)Resilience and seizing opportunities
Small-scale fisheries and aquaculture businesses that thrived during the COVID-19 pandemic in South and Southeast Asia
2022Also available in:
No results found.The study, "Resilience and seizing opportunities – Small-scale fisheries and aquaculture businesses that thrived during the COVID-19 pandemic in South and Southeast Asia", attempts to evaluate and compare the pre- and post-pandemic situation and scenario of the concerned groups of the fisheries and aquaculture industry in eight countries. It reveals how these groups survived by adopting innovations in various country contexts and social settings and how the production, supply and market continued operation. The study shows how responsive the government policies and interventions were in supporting the concerned groups. It also shows the preventive measures taken to contain the mass spread of the COVID-19 pandemic and the manner in which the community livelihoods were impacted by these measures. The case studies included provide evidence of the resilience of the small-scale fishers, aquaculture operators and fisheries-based business operators and illustrate how opportunities may be seized by them and others affected by similar pandemics and other natural disasters and events. The study sheds light on areas where more focus should be given so that all parties may be better prepared for future crises, have equitable and inclusive support policies, have transparency in policy responses as well as take into account gender equality. The recommendations of the study can be applied at national, regional and international level while adaptation policies, investment and action plans may be taken for the sustainabillity and resilience of small-scale fisheries and aquaculture businesses in the future.
