Overview of monthly mortality and sea water temperature during the sampling period. The dashed line shows the monthly mortality in the study-cage (No. 4), as a % of the total production cycle mortality in the cage. The continuous line shows the monthly mean temperature. The first peak in mortality (September) was due to a tenacibaculosis outbreak, while the second peak (December-January) was associated with high Parvicapsula pseudobranchicola intensities in the pseudobranchs. Arrows at top indicate when the presently studied samples were taken
