EcoFish A transnational project 2008 -2010

The EcoFish project aims to develop sustainable methods for producing Ballan wrasse for use in salmon farming. Partner institutions collaborate on research and information exchange to address sea louse infestation issues. Broodstock care, feeding, spawning techniques, and outcome protocols are detailed. The project establishes contact with end-users and emphasizes the importance of sustaining Ballan wrasse in their natural environment.

  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
