Sea Lice Monitoring and Control

All finfish farms are obliged to monitor for sealice on an ongoing basis and to take remedial action. This involves the inspection and sampling of each year class of fish at all fish farm sites fourteen times per annum, twice per month during March, April and May and monthly for the remainder of the year except December-January. Only one inspection is carried out during this period.

During 2020, a total of 209 sea lice reports (consisting of 108 MI reports and 101 farm reports) were received from 22 active farm sites.

One inspection was not undertaken by the Marine Institute on fish health grounds.
