  1. EcoFishA transnational project 2008 -2010 Environment friendly fish farming and use of cleaner fish Oddvar H. Ottesen

  2. EcoFish • Aim of the project • The project will deliver methods and technology needed to produce Ballan wrasse for use by the salmon farming industry in all of the partner countries. • EcoFish will do that through: • co-operation • joint research • organised exchange of information

  3. Participating R&D institutions • Bodø University College, Norway • Bioforsk Nord, Bodø Norway • Daithi O'Muruchu Marine Research Station (DOMMRS) Bantry, Ireland • Martin Ryan Institute, National University of Ireland (NUG), Carna, Galway, Ireland • Ardtoe Marine Laboratory (VFF),Ardtoe, Acharacle, Scotland, UK • Murman Marin Biological Institute, Russia (to be confirmed) Avdeling for fiskeri- og naturfag

  4. EcoFish - background • Infestation of an Atlantic salmon by the sea louse Lepeophteirus salmonis,. • Economic losses, all 3 countries more than 500 mill NOK? • Resistance against present treatment; several cases • Good results with wild caught cleaner fish • All partners have long experience and competence in hatchery • production of fish, including ballan wrasse Avdeling for fiskeri- og naturfag

  5. Why choose Ballan wrasse • Several species have been tested • Ballan wrasse most “popular” • Effective at low temperatures • Experience using wild BW • Similarities to production of other marine species e.g cod.

  6. Ballan wrasse broodstock • Broodstock established in all countries Normal spawning (May-August) Out of season spawning (September –December) (Light and temperature)

  7. Husbandry • Careful handling • Hiding places • Tubes and plastic bags • Low density • Stable environment

  8. Broodstock feeding Feeding 3 times per week Sausages; a mixture of; • Fish oil • Fish meal (broodstock feed) • Shrimps

  9. Spawning and eggproduction Ballan wrasse eggs in situ on a pipe substrate • Time May – August • 1 male, 8-12 females per tank • Demersal- stick to surfaces • Removeable spawning substrates • Disinfection of eggs important

  10. Outcome • Manual on hatchery production of Ballan wrasse • Protocol for use of Ballan wrasse in salmon cages Established contact with end users. All countries are involved.

  11. Ballan wrasse in its natural environment
