WP6 trends in biodiversity - Review impacts - Explore trends in catch data - Explore trends in survey data - Options for assessing trends in invertebrates - Identification of indicators

WP6 contributors/objectives Ifremer6 Cefas5 Imperial1 IPIMAR4 MI3 HCMR5 IEO1 MRI7 Participants + Case studies - review impacts - explore trends (landings/catch/surveys) - options for invertebrates biodiversity - selection of biodiversity indicators - spatial scale: Case study Objectives

WP6 deliverables D6.1 Relevance of commercial catch data (18) D6.2 Biodiversity indicators: trends, monitoring evaluation of information (24) D6.3 Patterns of distributions from survey (from some CSs)

Links with Marine Strategy Framework Directive (MSFD) Descriptors of MSFD: –1 - Biological diversity is maintained. [...] quality and occurrence of habitats [...] distribution and abundance of species are in line with [...] geographic and climatic conditions –4 - Marine food web [...] normal abundance and diversity [...] –6 - Sea-floor integrity [...] structure and functions [...] safeguarded [...] benthic ecosystems [...] not adversely affected –10 - [...] marine litter do not cause harm

Example: descriptor marine litter –10 - [...] marine litter do not cause harm

MSFD descriptors addresed in WP6 1: biological diversity (species diversity metrics) 4: food web, not addressed (*) 6: sea floor: can be addressed with VMS (availability?) – proportion of the seafloor impacted? – use of EU-CoralFISH results 10: marine litter: no data. –Define protocol for on-board observations in the long term monitoring strategy ? part of task 7.3: Prototype short- and long-term management and monitoring framework for deep-water fisheries and stocks in the NE Atlantic (*) preys mainly mesopelagic with little data

List of indicators Taxonomic distinctness, other diversity metrics from surveys Simple indicators (landings/catch/survey) : –S (richness) –proportion of large species, small species, chondrichthyans, vulnerable species (e.g. from observer data), etc –Discard rate –Number of discarded species Invertebrates : –Is it a matter of monitoring diversity or conservation of VMEs ? –Relevant spatial scale –Footprint approach: distribution of fishing effort frozen to current (VMS) ? Catch: on-board observations
