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 MarineStrategy 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

in management strategies ?– How to account for fish species diversity in MS ?– ...
