Colaboration The licelevel accordnig to national limits The use of chemicals to control lice. The effect on wildfish Fieldstudies in the fiord. Can other areas come up with a similar model? Rune Stigum Olsen, Hardanger Fishhealth Network (HFN) and SalmoBreed Royal Highland hotel, Inverness, 19 june 2006

2 The story Voluntariness solidarity - Coordination

3 Interactive Pest Management (IPM) Integrating of several products and control strategies; both biologicals, chemicals and culturals to overcome a disease problem. The target is to secure a sustainable industry with minimal influence of the surroundings. Voluntariness solidarity - Coordination

4 Voluntariness solidarity - Coordination

5 Establiched in March 2003 Fish health related work Salmonlice- monitoring and recommendation Liceteams, stricter rules for counting and a lower limit. Environmental data and data of the smolt put in sea. Monitoring tapeworms in fish, strategies Participating in diff. research projects Seaweeds and jellyfish Meetings Spread environmental friendly products and solutions Wrasses

6 What`s the point of a fishhealt network?

7 The river of Granvin - The westcoasts most injured trout- river because of salmon lice. Catches has been going down from 4500 kg to 70 kg seatrouts on 15 years

8 Potensialet for spredning av f.eks. lakselus i Hardangerfjorden Kilde for utslipp Det fargede vannet kommer fra utslippskilden Vannet tynnes ut - mørkere farge indikerer høyere konsentrasjon

28 The strategy.

29 Working together Environmental org. Authorities, Fishermen, Sportsfiskermen, farmers, university, IMR, other research, vets. Solidarity, openness and honesty are extremely important. Spread the good results on to the media Reduce the chance of getting resistance. Good economy! Politics and goodwill If one can succeed in an area like Hardanger, one can probably succeed in every areas. Voluntariness solidarity - Coordination

38 Coordinated delousing. Using the right stuff on the correct time Consideration to both wild and farmed salmon The development stages and spreading pattern of the lice, monitoring of the fiord. 1. may and 1 january

39 Delicing strategy Oneyearsmolts: 1. Put out in april/may, wrasses 2. Slice (Emamectin) desember, 1,5-2,5 kg 3. Wrasses juli year 2, 3,5-4,5 kg 4. Eventually bath threatment year 3. In februar to April. (if not harvested) Remember. The liceproblem is mainly a problem on big fish, over 3 kilo! Voluntariness solidarity - Coordination

40 Zero smolt: 1. Put in sea in oct/nov. 2. Slice the two first weeks of desember, 0,15-0,45 kg. 3. Wrasses, 2 year, july. 4. Evnt bath threatment febr- march 3 year. The liceproblem is mainly a problem on big fish, over 3 kilo! Voluntariness solidarity - Coordination

43 Save a lot of money and win goodwill! Direct cost of the drugs Better growth, Feedfactor Red. chance of diseases Better quality Goodwill in the public Voluntariness solidarity - Coordination

44 The use of drugs before and now Before 2003: Spring salmon: 2 times Slice 3 times bath 0- year old salmon: 2 times Slice 3 times bath After 2003: Spring salmon: Wrasses 2 periods 1 time Slice 0- year old salmon: 1 time Slice Wrasses 1 period 1 bath threatment Voluntariness solidarity - Coordination

45 The Hardanger fishfarmer: Has saved 3,1 mill Euro (25 mill NOK) a year. And a reputation and goodwill that is impossible to quantify. The possibilities in Scotland should be even higher.

47 Fieldstudies in the H-fiord Trawling and cage trials in direction of the Marine Research Center (IMR in Bergen), Press release IMR 2005: one are approaching a level on lice so low that the wild stocks can live with it The lice sit. in spesially the inner parts has been dramatically much better last years -Svein- Helge Pedersen Still some distance to go for the trouts on the outer parts of the fiord. -Steinar Kalås, RB The low no of lice has saved our firms for big amounts of money when it comes to chemicals -Fishfarmers in the Hardanger fiord,

48 The river of Granvin The results of HFN`s work against the lice has spesially made good results in the inner part of the Hardangerfiord. The umber of returning smolts (returning to delice) has been much lower the last years. The number of spawning fish has been increasing a lot for both salmon and trout in the river. High density of fry Salmon in the river again. Sven Helge Pedersen- Hardangerfjorden Villfisklag

49 How to get started: 1. The drugs that are in use. What about Deltamethrin? 2. Wrasses 3. The working together line. No war! 4. Every fishfarmer in a area has to join in 5. Lead by a fishfarmer with guts 6. Counting teams, objective no. Monitoring every 14 d. 7. Homesite on www, put out the data 8. Present the economy in a good regimè 9. Arrange meetings to build down prejudiced opinions 10. Use the media to spread the good news.

50 Never forget that the fishfarming industry and the wildfish industry are playing on the same team. It is better with an active regimè than an inactive protection. Voluntariness solidarity - Coordination
