Coral gardens, kelp forest sponge beds, sea grass, meadows or submarine canyons often represent Essential Fish Habitats (EFH) as they are essential for the survival of fish. These areas are crucial for fish life stages as this is where they spawn, breed, feed and mature. The protection of Essential Fish Habitats will contribute to the recovery of overfished stocks. Looking at the state of the European fish populations, only a minority can be considered as well-managed, while 64% of the fish stocks are overfished in European waters. In the North East Atlantic alone, 51% of the stocks are still overfished, while the situation in the Mediterranean Sea looks even more shocking, with 97% of the European stocks overfished.
EU fisheries ministers continue to disregard science and to overfish stocks on the basis of short-sighted socio-economic arguments. It is undeniable that the Union's Member States must act immediately to stop overfishing and to recover all stock above healthy levels by 2020, at the latest. To achieve this objective, an effective protection of Essential Fish Habitats is needed. Safeguarding sensitive and critical habitats at certain life stages of overfished species will, in turn, contribute to the recovery and health of fish stocks. Sustainable management of fisheries could increase European catches by 57% (or 5 million tonnes) within the next 7-10 years. More fish in the ocean would mean more jobs in the fishing industry and more healthy fish on our tables.
The ecosystem approach to fisheries management and the political context
In the frame of the overall goal to end overfishing and reduce bycatch significantly, the requirement to conserve and enhance EFH completes the foundation for an ecosystem approach to fisheries management. That recognises the complexity of ecosystems and the interconnections among its component parts, so it usually refers to bycatch mitigation, multi-species management, protection of vulnerable ecosystems, and integrated approach. Several fisheries policies and legislations worldwide have already included the protection of EFH, e.g. FAO Code of Conduct for Responsible Fisheries (1995), the US Magnuson-Stevens Fishery Conservation and Management Act (1996), the MedFish4Ever Declaration (2017). Also, the European Common Fisheries Policy (CFP) establishes the ecosystem approach as one of its policy pillars to the ecosystem approach (Art. 2.3), and in particular, when adopting regional multiannual plans, specific alternative conservation measures based on the ecosystem approach shall be included for some of the stocks it covers (CFP Art. 9).
Main threats to EFHs
Science shows that human activity, such as trawling and sand dredging, are the main culprits behind the unhealthy state of seafloor habitats, which ultimately leads to the destruction of EFHs. Corals and sponges are particularly sensitive as often they grow only a few millimetres per year.
Bottom trawling is a widely-used fishing technique that is significantly responsible for a permanent disturbance of seafloor habitats, including Essential Fish Habitats. It is one of the most widespread and most destructive fishing practices, dragging everything it meets on its way.
Sand dredging is a notorious activity that uses heavy machinery to extract sand from the ocean floor. For decades this technique has been threatening the ecosystem in the Sound, a strait shared by Denmark and Sweden. It also occurs on shallow sandbanks along the entire Danish coast. In the Sound, dredging is not permitted in Swedish waters, but in Denmark, poor regulation and short-term economic interests have led to serious damage to the seabed and the marine life there, in areas that are feeding and nursery grounds for popular species, such as cod and plaice. According to International Council for the Exploration of the Sea (ICES), the recovery time frame of intense sand dredging areas varies from more than 10 years to “never”. Such a “never” scenario can be seen in Lomma Bay in Sweden, where the area was last dredged in the 1950s and sadly has not recovered.
Binding legal obligations in Europe through the European Common Fisheries Policy (CFP)
In Europe, the Common Fisheries Policy recognises the importance of EFHs, and most importantly, their effective protection to contribute to rebuilding and exploiting fish stocks sustainably by 2020. This a legal target to be reached before 2020, at the latest. Specifically, Article 8 of the CFP recognises the importance of Fish Stock Recovery Areas (FSRAs) to achieve this.
EU Member States are required to identify suitable areas essential to the fish life cycle based and to call on the European Commission to propose the protection of such areas from harmful fishing impacts. Finally, paragraph 3 of Article 8 shows it is the responsibility of the European Commission to integrate steps to protect EHFs under fisheries multi-annual plans.
Call on decision-makers to include Essential Fish Habitats in fisheries multiannual management plans
But in order to turn science into reality, we need good management. That's why EFHs need to be implemented in the context of multiannual management plans (MAP) that set clear stock recovery objectives. The EU is still far from implementing an ecosystem approach to fisheries management. So-called fish stock recovery areas (FRSAs) have unjustifiably received little political attention, and very little progress has happened so far, despite considerable scientific work conducted and invested over the years (Marea; MediSeH; Mantis; Balance; EFH-GIS; MaPACo).
The protection of EFHs through establishing FRSAs, a conservation measure described in Article 10 of the CFP, has not yet been included multiannual management plans for the Baltic and the North Sea but has been included in the Strait of Sicily, where 3 fish nursery areas have been protected.
In April 2016, Oceana carried out an at-sea expedition in the Sound and was the first NGO that systematically surveyed the dredged areas with an underwater robot camera. Over the last years, support from civil society and politicians to ban sand dredging in the Sound has increased. Following Oceana’s work there, Danish opposition political parties presented a proposal to stop sand dredging in the Sound in May 2016.
In 2011, Oceana launched a proposal (the Oceana MedNet project) for the first comprehensive network of MPAs for the Mediterranean. The proposal includes a variety of sites, such as seamounts, canyons, banks, mud volcanoes-features – all of which are connected to essential fish habitats, which need proper protection.
