Sea Lice

Sea lice are microscopic parasitic copepods that commonly infest fish, especially salmon. They attach to the fish’s skin, fins, and gills, feeding on their skin and blood. This can cause stress, injuries, and increase the risk of infections for the fish. Sea lice are a natural part of marine ecosystems, but high numbers can become problematic, particularly in aquaculture farms where fish are densely stocked. Managing sea lice levels is essential to protect fish health and ensure sustainable fishing practices. Control methods include treatments, cleaner fish, and farm management strategies.
