The total number of sea lice and sea lice per fish reached a YTD low this week. However, farmers have used more sea lice treatments in June compared to last year, which is a negative and also a signal of high sea lice mitigation costs.

This week, the average sea lice count for Norway is 0.10 per fish which is in line with last year. Remember that the max limit is 0.5 sea lice per fish.

 

No county currently has above 0.2 sea lice per fish (which is the requirement for future growth in Norway). However, most sea lice per fish is found in Nord Trøndelag, Møre and Romsdal and in Hordaland (west Norway).

 

 

Møre & Romsdal and Hordaland also have the highest sea lice concentration due to the high number of fish in the sea in these regions.

 

 

Main conclusion on sea lice level:
  • According to Lusedata, the average count in Norway is 0.10 lice per fish which is in line with last year and down from  0.11 last week.
  • Some regions have fairly low levels and markedly below last year, such as the northern part of Norway.
  • Other regions are struggling more, for instance regions in west and West Norway, with around 0.2 sea lice per fish.
  • In general, the level of treatments in Q1 was below 2014. Q2 kicked off with less treatments but has been higher in June.
  • Remember that treatments are costly and negative for the fish health and growth.
