VMS data




        1. Time-series of VMS data or VMS plots


Please complete the table below and append all available time-series of data or VMS plots, disaggregated by fleet ID where possible:-


Fleet ID

Is VMS monitoring mandatory?

Do VMS data exist?

State years
Are VMS data available for scientific analysis?

If an EU fleet, has funding for VMS been claimed under the DCF?

Have VMS data been linked with logbook or observer data?

Have they been post-processed to identify fishing gear?

Is a VMS footprint available for each fleet?

(1) stands for French Bottom Trawl deep-water species (intercatch ID, to be checked)


        1. Available analyses of VMS data


[Please review any analyses of VMS data carried out for fleets fishing your stock.]
No previous analyses of VMS data was made. VMS data have no been available for scientific projects before 2009. A time series of VMS data from 2003 to 2008 has been made available and updates will be provided yearly. This is in line with the requirement from the Data collection regulation. Charts of the effort distribution of the French deep-water licensed fleet show that (i) the fleet operates on deep-water grounds to the west of Scotland, as expected, (2) a significant proportion of the effort of licensed vessels is spend on the shelf, namely in mixed trawl fisheries in the Celtic Sea and in saithe fishery in the Northern North Sea.

        1. Improvement of availability, quality and use of VMS data


[How could the coverage, availability, quality and use of VMS data be improved?]
It is likely that increasing the frequency of recording to 15-30 minutes would improve VMS data. This however requires confirmation based upon analysis during the project and depend upon the interest for management of VMS data. VMS data allows to identify where fisheries operate and are efficient for control issues. Their usefulness for scientific and assessment issues in deep-water fisheries requires confirmation. The distribution of the French demersal deep water fleet effort based upon VMS is consistent with other data and may not provide significant additional knowledge and data for stock assessment. The usefulness of VMS data with regards to Vulnerable Marine Ecosystem (VMEs) is another question, which might addressed both in Deepfishman and CoralFISH.
