  1. COBECOSCosts and Benefits of Control Strategies Status of WP2- Data collection at September 2007 Italian case study: GSA 9 bottom trawling fishery Loretta Malvarosa (malvarosa@irepa.org) Paolo Accadia (paolo.accadia@port.ac.uk) COBECOS II meeting, 5-7 September 2007, London

  2. The case study area: GSA 9. Ligurian and North Tirrenian Sea GSA 9 COBECOS II meeting, 5-7 September 2007, London

  3. General setting of the fishery • GSA 9 bottom trawling fishery is a multi-species and multi-gear fishery. • The fishery is focused on the bottom trawl segment, that is on vessels fishing exclusively or predominantly (fishing days >50%) with trawl nets. • Multi-gear fishery: even if trawling is predominant, vessels are provided, in many cases, by more than a license (in most cases by licenses for gillnets and long-lines). • Multi-species fishery: > 45 species. COBECOS II meeting, 5-7 September 2007, London

  4. General setting of the fishery – Indicators 1 • Target species: first 5 species in terms of value on the average of the last 4 years. They represent, on average, 46% of total landings in value. COBECOS II meeting, 5-7 September 2007, London

  5. General setting of the fishery – Indicators 2 • Target species: trend in the last 4 years of value of landings (mio €). COBECOS II meeting, 5-7 September 2007, London

  6. General setting of the fishery – Indicators 3 • Ratio of demersal Vs. pelagic catch (volume). COBECOS II meeting, 5-7 September 2007, London

  7. General setting of the fishery – Indicators 4 • Coastline adjacent to fishing areas. • Landing ports COBECOS II meeting, 5-7 September 2007, London

  8. General setting of the fishery – Indicators 5 • Effort: days at sea. COBECOS II meeting, 5-7 September 2007, London

  9. Technical characteristics of the fleet – Indicators 1 • Size of the fleet: no. of vessels, tonnage and engine power. COBECOS II meeting, 5-7 September 2007, London

  10. Biological characteristics of the fishery – Indicators 1 • Official landings from project fisheries (tons). • Landings are available by single species since 2003; by group of species (graph) since 2000. COBECOS II meeting, 5-7 September 2007, London

  11. Biological characteristics of the fishery – Indicators 2 • Total estimated removals from sea of stock of target species (includes only landings by other fleets not included in the project; data on discards are not available) – tons, 2003-2006. COBECOS II meeting, 5-7 September 2007, London

  12. Biological characteristics of the fishery – Indicators 2 • Total estimated removals from sea of stock of target species: share of bottom trawlers on all the fleet segments operating in GSA 9. COBECOS II meeting, 5-7 September 2007, London

  13. Biological characteristics of the fishery – Indicators 3 • As far as other biological characteristics of the fishery , IREPA has taken contact with relevant national biological institutes in order to gather all the necessary data. • At the moment we are waiting for data. In our opinion no relevant difficulties will be encountered in collecting this type of data. COBECOS II meeting, 5-7 September 2007, London

  14. Socio-economic characteristics of the fishery – Indicators 1 • Landings value (mio €). • Landings in value are available by single species since 2003; by group of species (graph) since 2000. COBECOS II meeting, 5-7 September 2007, London

  15. Socio-economic characteristics of the fishery – Indicators 2 • Prices of target species, 2003-2006 (€/kg). Table shows only price of target species. COBECOS II meeting, 5-7 September 2007, London

  16. Socio-economic characteristics of the fishery – Indicators 3 • Economic data (income, costs, G.V.A., gross cash flow) – mio €, 2002-2003. Gross cash flow is preferred to net profit because the estimation procedure of capital costs is changed in the latest years. COBECOS II meeting, 5-7 September 2007, London

  17. Management and enforcement of the fishery • The text and the data harmonisation related to the management of the fishery is under construction. • As far as the enforcement data, IREPA has taken contact with Harbour offices in order to gather all the necessary data. At the moment no data have been delivered. • Taking into account the level of detail requested by the project on the enforcement data, we think that some difficulties could be encountered in gathering all the data. This could imply, in some cases, the use of estimation procedures. COBECOS II meeting, 5-7 September 2007, London
