Workshop: Good Environmental Status (GES) indicators for pelagic ecosystems
Source: ICES News
In conjunction with ICES, representatives from several large EU projects came together this week to address the subject of Good Environmental Status for pelagic systems.
Working with ICES, the EU projects MyFISH, EURO-BASIN, and DEVOTES held a workshop in Charlottenlund, Denmark 3-5 April, to investigate how the concept of MSFD Good Environmental Status (GES) can be applied to the pelagic ecosystem and fisheries that exploit pelagic fish.
With most of the current paradigm with regards to Good Environmental Status (the targeted outcomes of the EU's Marine Strategy Framework Directive) for fisheries having been based on demersal fish, pelagic fisheries and fish were considered as operationally and biologically different. The management objectives for pelagic systems have been identified through a participatory process hosted by Myfish which included industry, management, scientist, and NGO representatives. These objectives were then used to identify the appropriate driver, pressure, and state indicators building on the work in EURO-BASIN.
In the joint workshop, the links between objectives and indicators were explored for a range of examples highlighting the importance of the biology and the interaction between the pelagic ecosystem and humans. The workshop concluded that considering Maximum Sustainable Yield (MSY) targets alone will not fulfil GES objectives with regards to, for example, the genetic, phenotypic, and behavioural dimensions. The MSY approach also does not specifically consider habitat and bycatch concerns.
The workshop will produce a paper entitled 'Identifying pelagic ecosystem indicators for management'.

A list of objectives for Pelagic Ecosystem GES indicators was generated by the MyFISH project stakeholder consultation. The work in EURO-BASIN provides the basis for proposing ecological indicators and reference points for Norwegian Spring Spawning Herring (NSSH), mackerel and blue whiting for the following stock related objectives:
Further, work carried out on using acoustics to characterize pelagic ecosystems provides indicators for the community level objective, though reference levels are more difficult to determine:
Finally, a structured way for selecting appropriate pressure indicators and reference points for each objective and in relation to the ecological indictors will be presented.
