Visibility poor at time of inspection due to wind and swell which were increasing throughout the inspection. Fish were deeper in the water, could be observed on camera system shoaling well. 2 dead observed across site. Two fish removed for VMD appeared in very good condition.
Lumpfish were stocked in Decemeber 2019, these did not appear to have had an impact on adult Lep numbers. Site had planned a physical treatment using the hydrolicer, however this was delayed due to weather and demand for the hydrolicer elsewhere. Numbers have been elevated since beginning of November 2019, recent hydrolicer treatment conducted 29 &
30/01/20, this has reduced sea lice counts but still above the reporting levels.
Fish showed good feeding response.
Mortalities are now disposed of to Pelagia rather than TWMA, this is the same for all SSF sites in Shetland, small volumes will go to Waste to Energy plant in Gremista.
No bath treatments conducted for sea lice this cycle. 4 SLICE treatments and physical treaments.
