No records of lumpfish offsite maintained as numbers are not known, the numbers are counted and recorded at Mallaig harvest station along with records of wild fish that have been transferred.
Lumpfish mortalities increased December 2018 (5168 no diagnosis), January 2019 (4031 No diagnosis), February 2019
(5332 atypical furunculosis) and March 2019 (5143 atypical furunculosis), April 2019 (5168,(no diagnosis) , florfenicol had been administered.

Elevated mortalities due to gill issues currently an issue. Mortalities related to gill issues began during week 35 with a marked increase in week 39.
Salmon mortalities week 39 4689 (0,54%), week 40 7448 (0.86%), week 41 14571 (1.69%), wk 42 5691 (0.84%), wk 43 32494
(4.86%), wk 44 (2.02%) 11109, wk 45 10074 (2.08%)
Additional mortality peak recorded in week 26 6906 (0.82%) and week 27 4287 (0.49%) attributed to post treatment losses, this also affected cleaner fish mortalities with 9947 and 5389 recorded.
Cleaner fish mortalities have been elevated also with 2324 recorded for the last four week in the wrasse being attributed to atypical furunculosis, lumpfish mortalities have been 5938 due to pseudomonas and handling.
Sea lice numbers have been above the CoGP recommended threshold for treatment since week 39 with a breech of the reporting threshold in week 45 (4.72) and week 42 (4.93)
Gill anaemia a significant problem. At the time of inspection two boats were conducting freshwater treatments. A number of lethargic fish were observed in the pens however these difficult to catch with a hand net but five fish were removed for further examination and diagnostic sampling.
Extremely poor weather condition made stock inspection difficult.
Due to ongoing issues on site a meeting with the manager could not be arranged as he just too busy therefore some records could not be inspected and some details not clarified. Sea lice and mortality data was provided prior to the inspection as well as stock details for the salmon however some information was not available.

Additional peaks in mortality 2020 Wk 45 - 11,275 (2.08%) due to gill infections (10,074) and anaemia (1,201). 2020 Wk 46 -
17,884 (3.82%) due to gill infections (8,735) and FW treatment loss (9,149). Mortalities reduced significantly the following weeks.
Lumpfish mortalities - For April total mortality 2,595 (4.78%). Other peaks in mortality - Nov 2020 9,700 (8.38%) (7,692 transport losses), Dec 2020 5,165 (5.91%) (mainly without diagnosis), Jan 2021 4,522 (11.54%) (mainly without diagnosis, some handling sea lice mortality). Following discussion with the manager it was confirmed that the mortalities recorded without diagnosis should have been recoded as post treatment mortalities.
1 side swimmer and 1 mort observed. Not removed for sampling.

Last cycle issues with gill health.
Some dead wrasse observed in 2 pens. 2 moribund salmon noted but away from edge of cage so not removed. Poor visibility due to weather conditions. [Original PDF]
