Resilient rivers – the place we would like to be

CCB • August 22, 2023

August 2023 - “Over several days, we explored firsthand the significance of freshwater ecosystems for nature-based water management, sustainable forestry, waterway management, environmental accident mitigation, the practical challenges of rewilding, and so much more. It was a truly immersive experience that highlighted the beauty and fragility of rivers and reinforced the need to protect these ecosystems” commented Valerie Kendall, from MKO Ireland and one of the lecturers of the 4th edition of River University, which took place in the unique Oder Delta landscape, in Germany, on 31 July-4 August 2023.


The environmental catastrophe in the Oder river in 2022 still shows its negative consequences nowadays - along with new issues and challenges - making it difficult to reach a full and smooth recovery. To experience, understand and discuss the importance and the need of an integrated water management plan in the whole basin, the participants of this year's edition of River University gathered in the Oder river basin, hosted by the co-organizer Rewilding Oder Delta.


KEY PROBLEMS IN ODRA BASIN


The biggest problems of the Oder river and its basin relates mainly to the poor quality of its surface waters and its hydromorphological transformation [1]. Above-normal amounts of toxic polycyclic aromatic hydrocarbons (PAH) and heavy metals are present in surface waters which result in poor chemical status of Oder waters.This pollution comes from fossil fuel burning, transport and industrial emissions. Relying on fossil fuels in transport, energy and heating, doesn't help the recovery. Coal mines, which still function in the trilateral Odra basin, are responsible for brine discharges that have a significant impact on the high salinity of the Oder river. Additionally, large technical investments in new dams for inland navigation and hydropower stations negatively affect the river's natural capacity to self-regulate, and by consequence contribute to the current climate crisis. 


In such a vulnerable riverine ecosystem, the concerns are high both in the Polish and German borders. 




THERE IS STILL HOPE 


Data science gives hope to the local communities: the Oder River is alive [2]. Different species of fish and conditions for breeding are present, yet it's our human work to be done to help this river to return to its full swing of life. 


A coordinated approach of the different states (Germany, Poland and the Czech Republic) is essential: responsible ministries as well as the lower authorities and intergovernmental organizations like the Helsinki Commision (HELCOM) and the International Commission on the Protection of the Oder against Pollution (ICPO) have to cooperate with each other for the management and protection of the Oder basin.


“The pressure on the Oder river is high and it’s not the only one. This is the point when catastrophe only waits to appear.”, commented Pavel Danihelka from UNECE Joint Expert Group on Water & Industrial Accidents, during River University 2023 [3].


Continuous water quality monitoring is critical for detecting and preventing pollution discharges. Still, in the entire territory of the international basin of the Odra River, this activity is not being carried out now at any locality. It was done in the period 2004-2014, helping to discover and record a number of cases of significant deterioration of the biological quality of waters, but despite the advantages the river basin management institutions stopped the activity after ten years [4]. Also, macroinvertebrates can play a role in biomonitoring, providing valuable information on the trends of biological changes based on their role in the ecosystem and unique characteristics [5].

INPUTS FROM RIVER UNIVERSITY 2023


During the 5-days event, speakers, practitioners and guides stressed the importance of river´s resilience, the ways to improve it, and urgency to speed up the fulfillment of the EU Water Framework Directive (WFD) to protect our biodiversity including the Odra river waters and natural resources that rely on them.


The lectures, field visits and expert discussions revealed that there are plenty of tools available to reduce risks and avoid critical situations, e.g.:


“We strongly believe restoring ecosystems on a landscape scale is achievable when various institutions, businesses, organisations and individuals cooperate and share the same vision. We are excited to see the new collaborations that have emerged from the River University, bringing us closer to achieving this goal.”, remarked Ewa Leś and Peter Torkler, co-organizers of River University 2023.

The Oder river is not only an infamous example of what can happen when human pressures damage the environment, but it could also represent a good example of holistic approach and joint transboundary improvements to make the recovery possible [8] and to ensure the resilience of the river.

NGOs urge stronger action as 2027 Baltic Sea fishing limits fall short of securing full recovery of fish populations

By CCB • October 27, 2026
27 October 2026 , Luxembourg - EU fisheries ministers increased central Baltic and Bothnian herring catch limits beyond the European Commission’s proposals and significantly increased the sprat catch limit, falling short of the precaution needed to protect the role of herring and sprat in the Baltic Sea food web. The Council also rejected proposed cuts to accidental catches of severely depleted cod and western Baltic herring populations. NGOs warn that fishing limits remain too high and urge EU ministers to follow the agreement with concrete plans to rebuild depleted fish populations. Herring: further measures needed to safeguard fragile recovery and protect vulnerable populations EU fisheries ministers increased the catch limit for central Baltic herring to 165 228 tonnes, a 71% increase compared with 2026. The population has shown signs of improvement after years of depletion. However, the central Baltic herring population remains vulnerable, and rebuilding must restore healthy age and size structures as well as overall abundance. Although below the scientific headline catch advice, the Council’s decision exceeds the Commission’s proposal, which was more precautionary and recovery-oriented and should have been followed by the ministers. “Ministers have recognised the need for caution, but still allowed more herring to be caught than the Commission proposed. These vulnerable populations need a stronger chance of lasting recovery, with clear rebuilding targets, a timetable for reaching them and measures that are implemented and enforced ,” said Cathrine Pedersen Schirmer, Senior Fisheries Policy Advisor at Coalition Clean Baltic. For Bothnian herring , ministers retained the three-month spawning closure but increased the Total Allowable Catch (TAC) by 12% , despite the population remaining below healthy levels. The Commission’s proposed TAC for this fish population was already a compromise between population rebuilding and maintaining fishing opportunities. The agreed higher TAC poses a risk to the recovery of the Bothnian herring population and creates increasing uncertainty for the industry. “ Fisheries decisions must also account for the risks to fish population recovery. Even catch limits within the ICES advice range can leave stocks at risk of remaining below the biomass levels that should trigger recovery measures. Fishing opportunities must give depleted populations a real chance to recover to healthy level s,” said Beatrice Rindevall, Chairperson of the Swedish Society for Nature Conservation. The Gulf of Riga herring TAC was also set above NGOs’ recommendations, with an increase of 11% compared with 2026, despite the recent decline in its spawning biomass and its importance to the Baltic food web. Lower limits for this fish population would have better supported population health and long-term resilience. Sprat: recovery must extend to the Baltic Sea food web The sprat agreement remains a significant concern. The Council’s decision, in line with the Commission’s proposal, to increase the sprat catch limit by 44% to 291 590 tonnes exceeds the level NGOs recommended. Although the population has increased, the agreed limit does not sufficiently account for sprat’s importance as prey for cod, salmon, seabirds and other marine wildlife, persistent catch misreporting or the risk of catching vulnerable herring alongside sprat. “ Herring and sprat are vital to the Baltic Sea ecosystem. When setting fishing opportunities, decision makers must leave enough prey in the water to support predators like cod and salmon, to rebuild ecosystem health and align with the EU’s nature restoration ambitions ,” said Justyna Zajchowska, Fisheries Lead for WWF Baltic Sea Programme. Salmon: no increase in catch limits, but stronger protection needed NGOs welcome the decision not to increase salmon fishing opportunities. However, fishing should be restricted to compensatory hatchery-released salmon or salmon from rivers where populations are at full reproductive capacity. Fishing on vulnerable wild populations must be avoided and, if returning salmon numbers are insufficient, additional adaptive management measures should be deployed immediately, considering the impact of recent poor spawning runs. “ Good returns to some large rivers are encouraging, but they do not demonstrate recovery across the Baltic region. Many smaller river populations remain in serious difficulty. We need fishing restrictions that protect those vulnerable salmon throughout their migration and allow enough fish to reach their spawning grounds ,” said Thomas Johansson, Chairman of Östersjölaxälvar i Samverkan and Secretary General of the Baltic Salmon Fund. Cod, western Baltic herring and plaice: Council misses opportunity to curb bycatch Both Baltic cod populations and western Baltic herring remain severely depleted. Targeted cod fisheries remain closed, while ministers retained the small-scale fisheries exemption for western Baltic herring. Yet ministers agreed bycatch quotas well above the Commission’s proposals for 2027 and at the same level as 2026, falling short of the protection sought by NGOs. For all three populations, the agreed bycatch quotas permit continued catches despite ICES advice for zero catch. The Council’s decision to increase the plaice TAC to 11,237 tonnes , well above the level NGOs recommended, missed an opportunity to secure a reduction in accidental cod catches. The decision also does not reflect the very low reported landings of this species. Declining weight and condition of plaice also warrant greater caution. The TAC must be combined with effective enforcement of mandatory selective gear to reduce cod bycatch and the implementation of the landing obligation. Annual fishing limits must support lasting recovery The Council’s decisions on Baltic Sea fishing opportunities for 2027 are not ambitious enough to secure restoration of all Baltic Sea fish populations. These decisions should be seen in the context of last year’s joint commitment by the European Commission and Baltic Sea Member States to seek dedicated scientific advice from ICES on rebuilding pathways for fish populations. In the absence of such rebuilding-oriented advice, and whilst we are waiting for it, decisions should be more cautious and based on the available recovery-focused catch options provided by the scientists in their traditional advice. Fisheries management must also support EU marine restoration objectives and the achievement of good environmental status in the Baltic Sea. Restoring fish populations and food webs is essential to the recovery of the sea itself and to the long-term future of Baltic fisheries and the coastal communities that depend on them.

CCB's submission on sustainable fishing in the EU

By CCB • August 31, 2026
Uppsala, 31 August 2026 - Coalition Clean Baltic (CCB) welcomes the Commission’s recognition that declining fishing pressure has not consistently delivered higher biomass, that recruitment and biomass are deteriorating for a number of stocks, and that Baltic fisheries urgently need rebuilding trajectories. These findings must now shape the Council’s decision on the 2027 fishing opportunities and the Commission’s position during the Council negotiations. The poor status and decline of many Baltic Sea fish populations have been documented over several decades and show that the ecosystem is in severe distress. Cumulative human pressures have contributed to major ecosystem shifts, and at the same time climate change is making the shallow, semi-enclosed Baltic Sea warmer and less saline. These combined pressures affect not only fish biomass but also recruitment, population age and size structures, species interactions and the functioning of the wider food web. The Baltic crisis reflects the persistent failure to fully implement the CFP and the Baltic MAP, including their precautionary safeguards and the legal obligation to apply ecosystem-based fisheries management. Fishing opportunities for 2027 must therefore mark the first concrete step towards ambitious, timebound rebuilding trajectories that reduce fishing pressure and enable depleted populations to recover to healthy levels. These trajectories must include implementation of an ecosystem based approach by accounting for species interactions, food-web needs, habitat conditions, environmental and climatic change and scientific uncertainty, while reinforcing, not replacing the CFP’s objectives and the Baltic MAP’s existing safeguards in Art. 4.6. The Commission’s 2027 proposal is now before the Council. The October Council must turn the commitment to rebuild Baltic fish populations into measurable action by adopting fishing opportunities that deliver rapid and sustained recovery. Under no circumstances should the TACs adopted be higher than levels proposed by the European Commission. Fishing opportunities aligned with scientific evidence, legal safeguards and ecosystem needs are the basis for both a recovering Baltic Sea and viable fisheries in the long term.
