Action 6.1. Exploitation data

ACTION 6.1 EXPLOITATION DATA – 26-28/10/10, RENNES

Objectives

Exploitation data in CHARM 3 Atlas :Fishing effort and landings for main gears and

main exploited species Using different available data sources

• Community Fishing Fleet Register• Logbook : long-term information, coarse scale (ICES rectangle)• VMS : from 2005 only, fine-scale effort data

Common UK-FR methodology and presentation• Common concepts (fleet / metier…) and referential data (gear,

species…)• Comparison of FR and UK data availability• Common methodology for data analyses (especially for VMS )

Underlining the lack of information and the reliability of data : • Logbooks and VMS are not exhaustive identification of

percentage of vessels without logbooks among the whole fishing fleet active in the Channel

ACTION 6.1 EXPLOITATION DATA – 26-28/10/10, RENNES

Our approach

To identify vessels active in the Channel and to estimate indicators

ACTION 6.1 EXPLOITATION DATA – 26-28/10/10, RENNES

Selection of vessels active in the Channel

Proposition of methodology for French vessels without

log-books:• Criterion for decision rules based on Fleet Register :

vessel length, port of registration

• Rules checked with activity calendars for 2000 – 2008

• Rules applied for French vessels without log-books / national fishing forms before 2000

ACTION 6.1 EXPLOITATION DATA – 26-28/10/10, RENNES

Perspectives :

Cefas to apply similar methodology to identify UK

Channel vessels (based on experts knowledge when no

log-books?)

To use VMS data to improve the identification of

Channel vessels (FR, UK, foreign) from 2005

Selection of vessels active in the Channel

ACTION 6.1 EXPLOITATION DATA – 26-28/10/10, RENNES

VMS data processing

• Two different methodologies between Ifremer and Cefas

- Geographical allocation of effort

- Speed threshold

Ifremer : FR vessels are fishing when net speed < 4,5 knots

working on specifying threshold per gear

Cefas : UK vessels are fishing when net speed = [1;6] knots

French methodology maybe more accurate but less easy to run

B

Bx

Ifremer : hypothesis of straight-line tracks between two VMS spots.Allocation of effort per cell of the grid.

Cefas : Allocation of total effort between 2 spots to cell where is located the point B.

VMS data processing

Perspectives• Globally, results seem to be similar with both methodologies

at a coarse scale. More differences with a fine-scale resolution;

• Ifremer and Cefas are currently applying their own methodology on common data set comparison and choice of a common methodology.
