10 European Lobster – Logbook/LPUE

11 Development of New Assessment Areas

12 Development of New Assessment Areas

13 Lobster Fecundity Establishing egg production within Orkney Lobster
Inclusion of information within stock assessment Comparison of traditional method Vs non-invasive method.

14 Lobster Fecundity

15 Scottish Comparisons

16 Sea Bottom Temperature Apr 205 – Nov 16

17 Future Project Development: Common Whelk
EU wide MLS – 45mm total length Known geographic variations MLS unfit for purpose Historically overexploited – susceptible to recruitment overfishing Scotland Orkney

18 Future Project Development: Common Whelk
Proposed work: Define localised biological characteristics Size at maturity Sex ratios Size Frequency Sentinel fleet – Scientific pots landings/logbook AIS/tracking

19 Future Project Development: King Scallops
Scallop Fleet Engagement: No. operating dredgers No. operating divers Build upon OFA existing work: Juvenile tagging Look at historic data mining exercise: Fishermen Diaries Establishing reporting methodology: Logbooks?

20 Future Project Development:
King Scallops Development of Stock assessment surveys: Use existing OFA funding stream and vessel participation Methodology relating to surveys; Use of beam trawl for juvenile individuals Inclusion of Queen scallops? Important small scale inshore sector along side King Scallops
