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
