OSPAR Assessment needs for incidental bycatch OSPARHELCOM workshop
OSPAR Assessment needs for incidental by-catch OSPAR-HELCOM workshop to examine possibilities for developing indicators for incidental bycatch of birds and marine mammals Copenhagen, 3 -5 September Lena Avellan, OSPAR Deputy Secretary
Why is OSPAR arranging this workshop? Incidental by-catch identified as key threat to threatened and/or declining species and species covered by common indicators OSPAR applies – Ecosystem Based Management of Human Activities – Precautionary Principle Common indicators to assess the by-catch pressure currenty insufficient Recognition of ongoing work in several forums and the need for clarity on the most relevant work to be undertaken within OSPAR competency Good experiences in the past of joint workshops/meetings Ø Thorough discussions needed to inform future action
OSPAR Convention Annex V, Article 4 § 1. In accordance with the penultimate recital of the Convention, no programme or measure concerning a question relating to the management of fisheries shall be adopted under this Annex. However where the Commission considers that action is desirable in relation to such a question, it shall draw that question to the attention of the authority or international body competent for that question. Where action within the competence of the Commission is desirable to complement or support action by those authorities or bodies, the Commission shall endeavour to cooperate with them.
OSPAR Convention OSPAR Agreement on the Meaning of certain concepts in Annex V to the 1992 OSPAR Convention on the Protection and Conservation of the Ecosystems and Biological Diversity of the Maritime Area (Reference number: 1998 -15. 2) OSPAR agreed that references in Annex V to the 1992 OSPAR Convention on the Protection and Conservation of the Ecosystems and Biological Diversity of the Maritime Area to “questions relating to the management of fisheries” are references to the questions on which action can be taken under such instruments as those constituting: a. the Common Fisheries Policy of the European Community; b. the corresponding legislation of Contracting Parties which are not Member States of the European Union; or c. the corresponding legislation in force in the Faroe Islands, Greenland, the Channel Islands and the Isle of Man. d. the North East Atlantic Fisheries Commission and the North Atlantic Salmon Commission whether or not such action has been taken. For the avoidance of doubt, in the context of the OSPAR Convention, the management of fisheries includes the management of marine mammals.

5 th meeting under the Collective Arrangement May 2019, Gothenburg
Collective arrangement Joint OSPAR-NEAFC request to ICES for advice OSPAR Listed T&D species Gulper shark The advice is intended to generate a shared knowledge base upon which the organisations can take further measures respectively The advice should address the following aspects: a. information on fleets catching elasmobranchs and supporting the development and evaluation of additional approaches for bycatch mitigation. b. information pertinent to management actions related to impacts of pollution, climate change, and ocean acidification. c. information on e. g. seasonal changes in depth utilisation profiles, feeding strategies and differences between life stages and reproductive stages of the species with special attention to juveniles and gravid females. Portuguese dogfish Leafscale gulper shark
OSPAR threatened and/or declining species Listed mammals and birds for which incidental by-catch has been identified as a threat Little shearwater (Puffinus assimilis baroli) [Audobon’s shearwater (Puffinus lherminieri] – – Severity: Low It generally does not follow ships and is probably therefore less at risk from fisheries by-catch Balearic shearwater (Puffinus mauretanicus) – – – Severity: Not stated makes extensive use of fisheries discards. This fact, in addition to a potential increase in response to the decline in traditional prey species, means that it may also be adversely affected by incoming fishing policies directed at reducing Accidental bycatch on longlines and in fishing nets as a result of its congregatory behaviour and close association with fishing vessels. It can result in occasional instances of ‘mass mortality’ if large rafts of birds are present. Black legged kittiwake (Rissa tridactyla) – – Severity; Not stated Bycatch mortality in fisheries especially off the north-western United Kingdom Iberian guillemot (Uria aalge) – – Severity; High Gillnet bycatch, particularly after the spread of synthetic fishing nets, is considered as the main factor causing the observed large-scale decline in Iberian guillemot populations. Thick-billed murre (Uria lomvia) – – Severity: Not stated Incidental capture in fishing nets. Previously, (in the early 1970 s), offshore and nearshore driftnet fisheries for Atlantic Salmon Salmo salar took huge numbers of U. lomvia off south-west Greenland, mainly in late autumn
OSPAR threatened and/or declining species Listed mammals and birds for which incidental by-catch has been identified as a threat Harbour porpoise (Phocoena phocoena) – – Severity; High Large numbers of animals are taken as by-catch by a variety of fisheries. Porpoises are taken incidentally in several different gear types (driftnets, pelagic trawls, etc. ), but mostly in bottom-set gillnets Bowhead whale (Balena mysticetus) – – Severity: Low Entanglement in fishing gears can cause mortality or serious injury. As far as the OSPAR area Svalbard-Barents Sea (Spitsbergen) subpopulation is concerned, incidental mortality or serious injury from entanglement in fishing gear has not been reported. Blue whale (Balenoptera musculus) – – Severity: Not stated Entanglement in fishing gear. Although few entanglements have been reported, the risk exists. Northern right whale (Eubalena glacialis) – – Severity; Not stated Entanglement in fishing gears can cause mortality or serious injury. Because some of these deaths probably pass undetected, reported rates are considered as minimum estimates
OSPAR threatened and/or declining species Priority action by OSPAR Contracting Parties • Roadmap for the implementation of collective actions within the Recommendations for the protection and conservation of OSPAR listed Species and Habitats • Status assessments Guidance on the Development of Status Assessments for the OSPAR List of Threatened and/or Declining Species and Habitats (Agreement 2019 -05) Ø Assessing the status of these listed species and taking action to protect them is an OSPAR priority Ø Whether Listed species are appropriate to address through a common indicator requires further discussion during the workshop
Proposal for a new OSPAR MPA in ABNJ North Atlantic Curent and Evlanov Seamount MPA Conservation objective • Protection of 22 seabird species • Incl. T&D listed; Audobon’s Shearwater, Black-legged kittiwake, Thick-billed Murre Limited human activities Seabird by-catch noted as one potential issue to be further investigated
