  1. Fisheries MonitoringSystem, Economy and fisheries assessment • Improve resources and users data network • Include economical data • Improve fisheries assessment including economic and ecosystemic approaches • Evaluate the impact of actual or possible management measures P. Berthou Bay of Biscay- Iberian Taskteam IEO Vigo 25-26 February 2004

  2. Fisheries MonitoringSystem, Economy and Fisheries assessment • 2. National programdata collectionUE • 3. Fisheries InformationSystem database ISIH • 1. Fisheries InformationSystem SIH • 4. Network of fishing effort and environment parameters measurement on board fishing boats RECOPESCA • 5. Economy and fisheries assessment EDEER P. Berthou Bay of Biscay- Iberian Taskteam IEO Vigo 25-26 February 2004

  3. Fisheries InformationSystem (SIH) Monitors resources, harvesting and economics General objectives • standardize the collection, storage and processing of fisheries data • ensure validation and storage of fisheries data • improve the access to centralized data bases • elaborate fisheries indicators • produce synthesis for our laboratories, partners and the general public P. Berthou Bay of Biscay- Iberian Taskteam IEO Vigo 25-26 February 2004

  4. Fisheries InformationSystem (SIH) • The components • Fisheries statistics • Economics data • Sampling of landings • Observers on board • Oceanographic surveys • products of SIH • Methodology of SIH P. Berthou Bay of Biscay- Iberian Taskteam IEO Vigo 25-26 February 2004

  5. Fisheries Statistics Fisheries biologists need precise data informations per boat and per fishing operation and day at sea • gear • area • fishing effort • catch per specie (including non quota) At the moment, only available by fishermen ’s Log-books P. Berthou Bay of Biscay- Iberian Taskteam IEO Vigo 25-26 February 2004

  6. Recopesca Project Network of fishing effort and environment parameters measurements on board fishing boats. • Measurement network by sensors on board and on fishing gears • Only for scientific purposes • Sample of fishing boats - volunteers • With no cost and trouble for fishermen • With benefits for fishermen • Evolutive Complementarity with log books and Vessel Monitoring System (UE) P. Berthou Bay of Biscay- Iberian Taskteam IEO Vigo 25-26 February 2004

  7. Network of fishing effort and environment parameters measurment on board fishing boats Scientists Fishing industryelectronic log-book Data Base VMS Data Base SIH Return of Information GSM, GPRS or satelite • Sensors : • fishing effort • environment • temperaturesalinity • Depth • Terminal • GPS • use of existing computer, VMS • electronic log book bord data logger Sample of fishing boats volunteers • Passive gears : • duration of immersion • depth • number of gears or lenght • Active gears: • - duration of immersion • depth P. Berthou Bay of Biscay- Iberian Taskteam IEO Vigo 25-26 February 2004

  8. Fishing effort measurement • Active gears: trawls, dredges Measurment of duration of immersion and depth with one sensor on the gear. Combined with GPS data, this information can provide towed areas estimations. P. Berthou Bay of Biscay- Iberian Taskteam IEO Vigo 25-26 February 2004

  9. Fishing effort measurement Net lenght measurment counting Power Block ’s turns. One sensor is operating on board one netter of le Conquet (Britain). • Nets Additional measurment of immersion and depth through one sensor fixed on the gear P. Berthou Bay of Biscay- Iberian Taskteam IEO Vigo 25-26 February 2004

  10. Fishing effort measurment • Longline • Pots P. Berthou Bay of Biscay- Iberian Taskteam IEO Vigo 25-26 February 2004

  11. Environmental parameters measurement and profiles • Temperature • Depth • Conductivity - salinity • Turbidity • fluorimetry P. Berthou Bay of Biscay- Iberian Taskteam IEO Vigo 25-26 February 2004
