Extinction risks to whales, dolphins and porpoises – over 350 scientists warn in an open letter

CCB • October 12, 2020

On Friday 9 October 2020, an open letter from more than 350 cetacean scientists highlighting the real and imminent extinction risk to whales, dolphins and porpoises has been published. One of the populations under threat is the Baltic Sea harbour porpoise.

In this letter, scientists from all over the world highlighted that “of the 90 living species of cetaceans, more than half now have a concerning conservation status according to the IUCN , with 13 species listed as ‘Critically Endangered’ or ‘Endangered’, 7 as ‘Vulnerable’ and 7 as ‘Near Threatened’, whilst 24 species are ‘Data Deficient’.”

The cetaceans experts are asking for actions. The situation is urgent and it’s known that cetacean populations can be lost very quickly.
That’s why they call on:

  • countries with cetaceans in their waters to take precautionary action to ensure these species and populations are adequately protected from human activities.
  • all nations to both work with and strengthen the relevant international bodies that seek to address threats to cetaceans.

Ida Carlén, CCB Biodiversity and Nature Conservation Officer and harbour porpoise expert has been interviewed by the Swedish television program TV4 Nyheterna about the open letter, which she signed, and the status of the critically endangered Baltic porpoise population.

“Work is being done to take measures to save the Baltic porpoise, but we need to move faster.”

affirmed Ida Carlén.

in your country to help in the protection of these cetaceans.

The European Commission's evaluation confirms what environmental NGOs across Europe have long argued: the Common Fisheries Policy (CFP)'s challenge is not its design, but its implementation.
By CCB June 10, 2026
The poor status and decline of many Baltic Sea fish populations have been thoroughly documented over several decades, indicating that the entire ecosystem is in great distress. So far, policy interventions have not reversed, or even halted, the negative trend concerning many of these populations. The European Commission itself recently recognised in its Common Fishery Policy (CFP) evaluation report that progress on stock rebuilding is lacking and the number of stocks “ threatened by collapse due to impaired recruitment has increased during the reporting period ”. Fish populations that once formed the cornerstone of the Baltic Sea fishery, such as the eastern and western Baltic cod and the western Baltic herring, are now doing so poorly that the International Council for the Exploration of the Sea (ICES) is advising zero catch for these stocks. Yet, even with the targeted fishery being closed for some years now, none of these three stocks are showing sufficient signs of recovery. The condition (such as size and weight-at-age) of many flatfish populations, such as plaice, also raises alarm bells. The salmon spawning migration has fallen short of the target level in the past three years5. As a result, even the healthiest salmon stocks are now unlikely to produce enough smolts corresponding to sustainable levels in the coming years. To address the crisis facing Baltic populations and the broader ecosystem, political will and ambition to improve fisheries management, alongside full implementation of the CFP provisions, are needed. The recent INI report on the Baltic Sea Multi-Annual Plan shows that the European Parliament recognises the importance of ecosystem-based fisheries management as well as the need for consideration of environmental legislation when making decisions on fishing opportunities.6 Fisheries managers must now act swiftly and decisively on the commitment the Commission and Baltic Sea Member States made at last year’s October Agrifish Council to rebuild Baltic Sea stocks. This document presents the joint NGO recommendations regarding Baltic Sea fishing opportunities for 2027, prioritising long-term ecosystem health and sustainable fisheries management over short-term economic interests. The recommendations are based on the ICES advice, the objectives and requirements of the CFP8 and the Baltic Multiannual Plan (MAP), specifically to apply the precautionary approach and implement an ecosystem-based approach to fisheries management, and the objective of achieving Good Environmental Status (GES) under the Marine Strategy Framework Directive (MSFD). Last year’s overarching joint Briefing Series on TAC-setting, co-signed by almost 30 organisations across the EU and the UK, including environmental NGOs, recreational fishers, and fishing rights owners, remains valid and provides further context, background and detailed explanations on the cross-cutting issues raised in this document.
