Description
Summary:European countries have committed to restore and maintain populations of commercial fish species above sustainable levels. However, despite some progress made during recent years, the status of some fish stocks continues to be in a critical state. Thus, based on the latest available scientific information, Oceana has identified the over 20 depleted fish stocks in the Northeast Atlantic, to highlight their ongoing dire status and the urgent need for management measures aimed at their recovery. The list of Northeast Atlantic depleted stocks covers a diverse group of species (including pelagic, demersal, and benthic species) and sea basins, from the Baltic Sea to the west of Scotland and from the Barents Sea to Iberian waters. Species like anchovy, eel, herring, horse mackerel, Norway lobster, sardine, and whiting, among others, have one or more stocks that are known or considered to be depleted. The most extreme case is that of cod, with the highest number of depleted stocks (nine) across the whole region. The depletion of these stocks raises concerns not only about their status, but also about the possibility that their abundance may have fallen below tipping points that have negative biological and ecological implications, as well as adverse economic and social consequences, since the stocks cannot sustain direct exploitation. Their reproductive capacity and subsequent are impaired, and there is an increased risk of stock collapse. This situation also makes these stocks more vulnerable to anthropogenic pressures (such as habitat degradation and loss) and to environmental variation, including in relation to climate change. Most depleted stocks in the Northeast Atlantic are managed jointly by different parties, mainly by the European Union and the United Kingdom, through a solid regulatory framework that, if well implemented, would facilitate the recovery and sustainable exploitation of depleted stocks. Nevertheless, only very limited attempts have been made to apply measures for their recovery (e.g., catch limits ...
