Planning, Regulation and Management in off-shore aquaculture: Experience in the South of Spain

1. Planning, Regulation and Management in off-shore aquaculture: Experience in the South of Spain “Experiences in the South of Spain” Padilla, F.   Cofradia de pescadores de Conil de la Frontera.

2. Planning, Regulation and Management in off-shore aquaculture: Experience in the South of Spain Experience in the South of Spain Projects developed between 2000-2007. • First stage: TESTING TECHNOLOGIES. (2000-2003) • Second stage: NEW SPECIES.(2003-2006) • Third stage: FARMING.(2006-2008)

3. Planning, Regulation and Management in off-shore aquaculture: Experience in the South of Spain Experience in the South of Spain First stage. Testing Technologies(2000-2003) Main objectives. • Technology improvement of the aquaculture sector. • To search for new areas of aquaculture uses. Installation site. Installatión

4. Planning, Regulation and Management in off-shore aquaculture: Experience in the South of Spain Experience in the South of Spain First stage. Testing Technologies(2000-2003). Cage selection. • CORELSA. • Hercules 6000 m3. Surface cage. • REFA. • TLC 2000 m3. Flexible sumergible. • OCEAN SPAR. • Sea Station 3000 m3. Rigid submergible. Results. Oceonographic data: wavesHs= 5,5 m; wind=135km/h;current=73cm/sec • 25 T of fish in 12 months. • No fish scapes. • Surface structures need more maintenance

5. Planning, Regulation and Management in off-shore aquaculture: Experience in the South of Spain Experience in the South of Spain Second stage: New species (2003-2006). Main objectives. • Culture viability of new aquaculture species and characterization of the biological parameters.. • Continue with the first stage objectives and consolidate aquaculture in the area. • C. New installation site. • Current registered increased to 84cm/sec and the waves registered go up to Hs 6.2. Installation

6. Planning, Regulation and Management in off-shore aquaculture: Experience in the South of Spain Experience in the South of Spain Second stage: New species (2003-2006). Increasing the number of structures. Species.

7. Planning, Regulation and Management in off-shore aquaculture: Experience in the South of Spain Experience in the South of Spain Third stage: Farming(2006-2008). Main objectives. • Transfer technology to the aquaculture sector. • Involve the fishing sector. • Icreasing installations. 25 long lines- 4 sea station. • Target production 400 tonnes.(200 oyster-200 bass)

8. Planning, Regulation and Management in off-shore aquaculture: Experience in the South of Spain Experience in the South of Spain Third stage: Farming(2006-2008). Results. • Strong currents: • More flesh in the oysters. • Less fat in the fishes.

9. Planning, Regulation and Management in off-shore aquaculture: Experience in the South of Spain Experience in the South of Spain Regulation and managementexperience. Who will move offshore? Farmers Definition of offshore aquaculture. Advantages: • More than 3 milles. No visual impact. • Less environmental impact. • Use of submerged structures decreases maintenance. • The higher frequency of the currents allow increasing the cultivation loads, and decreases the growth time for the molluscs. • Less changes in cultivation conditions.

10. Planning, Regulation and Management in off-shore aquaculture: Experience in the South of Spain Experience in the South of Spain Regulation and managementexperience. Insurance. • No installation should start its operation without the corresponding insurance. • Insurance is available for offshore. • Insurance taxes. Annual decrease. • Stocking density. Can be increased with a rigid cage in offshore conditions.

Levy. • Mediterranean structures use to suffer accident because os aglomeration of cages. • Offshore aquaculture needs more area. • A reduction of fee in offshre areas is needed.

12. Planning, Regulation and Management in off-shore aquaculture: Experience in the South of Spain Experience in the South of Spain Regulation and managementexperience. Traffic maritime. • Important problem. • Offshore. Nobody driving the ships. • Our solution was go away from the traffic lines. Installation site

13. Planning, Regulation and Management in off-shore aquaculture: Experience in the South of Spain Experience in the South of Spain Regulation and managementexperience. Marketing. • Offshre sells. • Demand of this type of product. • Need for label regulation.

14. Planning, Regulation and Management in off-shore aquaculture: Experience in the South of Spain Experience in the South of Spain Regulation and managementexperience. Technology development. • Technology is available. • Production cost is reducing by less maintenance and longer life of the streuctures. • Stronger manufacture companies. Less cost of the structures.

15. Planning, Regulation and Management in off-shore aquaculture: Experience in the South of Spain Experience in the South of Spain Regulation and managementexperience. Technology development. Next step. Who? • The companies interested in developing offshore technology do not have enough financial capacity to face large scale research projects. • The big aquaculture materials companies are not interested in developing technology products if there is insufficient demand. • The administrations have difficulties in financing this type of projects in the long term due to its size. • If the research is carried out in private farms, the results are not distributed to the sector.

16. Planning, Regulation and Management in off-shore aquaculture: Experience in the South of Spain Experience in the South of Spain Regulation and management. CONCLUSIONS • Regulation is needed. • The farmer needs economic advantages. • Need of strong projects for technology development.
