  1. Scientific Use of Vessel Monitoring System (VMS) Data –NAFO Experience D4Science World USer Meeting, 25-26 November 2009, Rome Italy

  2. NAFO Convention and Regulatory Area D4Science World USer Meeting, 25-26 November 2009, Rome Italy

  3. NAFO Statistical Reporting Areas D4Science World USer Meeting, 25-26 November 2009, Rome Italy

  4. NAFO VMS Overview • Introduced in 2003 • Solely a Monitoring, Control, and Surveillance (MCS) tool – Enforcement and Compliance D4Science World USer Meeting, 25-26 November 2009, Rome Italy

  5. NAFO Vessel Monitoring System D4Science World USer Meeting, 25-26 November 2009, Rome Italy

  6. VMS Primer • Information transmitted as text strings(future XML) • Sent via Internet over HTTPS • Using North Atlantic Format (NAF) • Parsed and stored in a database • Delimited using “//” e.g. https://nafovms.nafo.int/input?application=NAF&method=send&message=//SR//AD/XNW//FR/FMC//RN/36769//RD/20080706//RT/0011//TM/POS//RC/XYXY//LT/48.175//LG/-45.301//DA/20080706//TI/0006//ER// D4Science World USer Meeting, 25-26 November 2009, Rome Italy

  7. VMS Message Types • Position (every 2 hrs) • CATCH • Catch on Entry • Catch on Exit • Transhipment • Daily Catch (on certain conditions) • Catch to be landed • Catch across Division 3 L (on shrimp fisheries) D4Science World USer Meeting, 25-26 November 2009, Rome Italy

  8. How can VMS be useful • Compliance • Fishing footprint • Effort Statistics (days present, fishing days) • Fishing distribution – spatial and temporal • Catch statistics – cross validation and verification D4Science World USer Meeting, 25-26 November 2009, Rome Italy

  9. Example: Percentage of fishing activity by depth D4Science World USer Meeting, 25-26 November 2009, Rome Italy

  10. Example: Depth distribution and fishing effort of shrimp fisheries in the NAFO Regulatory Area, as derived from VMS data. D4Science World USer Meeting, 25-26 November 2009, Rome Italy

  11. Example: Seasonal distribution of shrimp fishery effort D4Science World USer Meeting, 25-26 November 2009, Rome Italy

  12. Draft footprint of NAFO bottom fisheries based on Flag states submission and validated by VMS data D4Science World USer Meeting, 25-26 November 2009, Rome Italy

  13. Example:Footprint D4Science World USer Meeting, 25-26 November 2009, Rome Italy

  14. Example:Greenland halibut fishing effort distribution GHL Fishing Effort - Spatial distribution of fishing effort in the 700–2000 m depth zone in the NRA for 2006. The scale represents the logarithm of the number of hours fished / minute square per quarter (Campanis et al., 2008) D4Science World USer Meeting, 25-26 November 2009, Rome Italy

  15. Main issue • Confidentiality. VMS Data used solely for compliance purposes. • Article 26.6 of the NAFO Conservation and Enforcement Measures: … The Secretariat shall make available in a summary form to the Scientific Council following specific requests from the Fisheries Commission to the Scientific Council to determine fishing effort on and around vulnerable habitats and for any other purpose. D4Science World USer Meeting, 25-26 November 2009, Rome Italy

  16. Current LIMITATIONS • Position reports at 2 hours interval. Speed and course are not mandatory. • Beginning 2010 position reports at 1 hr interval. Speed and course are mandatory. D4Science World USer Meeting, 25-26 November 2009, Rome Italy

  17. Current LIMITATIONS • VMS Catch reports (COE-COX) unreliable. Catch reports transmitted at the end of the fishing trip (2 weeks to 3 months) • New requirement in 2010. Standardized weekly catch reports for all fisheries types (shrimp, ground fish, pelagic redfish). D4Science World USer Meeting, 25-26 November 2009, Rome Italy

  18. Current LIMITATIONS • NAFO VMS data confined in the NAFO Regulatory Area, i.e. international waters of the NAFO Convention Area. • It is estimated that only 10% of the fish catches in the NAFO Convention Area are in the Regulatory Area. • 90% of the fish catches are caught within the jurisdiction of the Coastal States, i.e. within 200-mile EEZ.
