The sustained increase in salmonids production has leaded to the proliferation of caligidosis caused by the sea lice Caligus rogercresseyi. In order to reduce the effects of this ectoparasite, a series of products and methodologies has been tested. Emamectin benzoate, Azamethiphos and pyrethroids (Deltamethrin and Cypermethrin) immersion baths have been tested, unfortunately all of them caused resistance of the sea lice consequently resistance towards these drug treatments is rapidly growing in most salmon farming facilities in Chile. An alternative method controlling the caligidosis, the synchronization of treatments between neighboring farms, has been introduced.
