Lobster Fecundity Establishing egg production within Orkney Lobster Inclusion of information within stock assessment Comparison of traditional method Vs non-invasive method.
Lobster Fecundity
Scottish Comparisons
Sea Bottom Temperature Apr 205 – Nov 16
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
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
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?
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
