2 2009 Very low levels of sea lice in fishfarms in spring 2009 Ekstraordinary growing on pens - August Extreme sea lice attacs from August Bad weather and unusual currents High levels of sea lice in aquaculture Reduced sensitivity / resistance Reduced effect of treatments Different strategies - Low level of coordination (time and type of drug) Challenges : Increasing drug-resistance Redused sensitivity/resistance to Slice (emamectin), pyrehroids, Multi-resistence Potential problem for wild salmonides Negative publication, reputation Sealice problem for farmed fish as well

7 Fundament Experiences from the PD-project (2007) Cognition : mutual problems, mutual solution Every company large and small Challenging process Agreement on cooperative measures Cooperation with authorities, scientific institutions, other industries. Authorities - making voluntary measures mandatory (regulations)

8 Strategy main elements 1. Mutual, binding agreements on cooperation 2. Cooperation with authorities 3. Exchange of, and coordinated and use of, information 4. Coordinated management and fallowing Large areas Reqiures changes in site structure 5. Syncronized (medical) treatments Systematic alternation / rotation of chemicals 6. Technical quality on treatment 7. Methods that are medicine independent / not inducing resistanse Cleanerfish 8. Prevent the spread of lice (copepodids) Filtration 9. Prevent the lice from settling on the fish Functional feeds, vaacine, breeding, 10. Knowledge 11. Regional surveillance and emergency plans 12. R&D

10 Strategic direction Not drug dependent measures Chemical/drug treatments The battle against lice has to be less drug dependent

11 What do we achieve? A more robust produksjon structure - Decreased risk and incresed ability to meet emerging diseases Better protection for wild salmonides Reduced production of sealice Reduced spreading of sealice Reduced risk of resistence / redused sensitivity to drugs Reduced risk of PD and other contagious diseases Lower overall mortality Better productivity
