The National Fisheries and Aquaculture Service (SERNAPESCA) will implement during this month new measures to control caligidosis - a disease that affects salmonids - in some groups of salmon aquaculture concessions located in the regions of Los Lagos and Aysén.
This pathology is caused by Caligus rogercresseyi, commonly called sea lice. In fish, this parasite causes an increased predisposition to get secondary infections and can even cause death.

These new provisions will be applied within the framework of the Specific Health Surveillance and Control Program (PSEVC) of caligidosis, a plan that establishes integrated disease management and whose objectives are the early detection of the parasite, the reduction of parasite loads and the control of its dissemination.
Control measures may include the application of pharmacological or non-pharmacological treatments, which may not exceed seven days.
In the case of Los Lagos, control measures will be applied in groups of aquaculture concessions 3B, 10A, 10B, 11 and 17A. Meanwhile, in the Aysén Region the new provisions will be implemented in 'neighborhoods' 18A, 18B, 18C, 18E, 22B, 22C, 23C, 24, 28A, 28B, 28C, 31A, 32 and 34.

The new control measures are established in the exempt resolution No. 4567 of 2019, Sernapesca, which is available on the website of the service.
This publication is part of a protocol of agreement signed with the Comptroller's Office, through exempt resolution No. 1275 of 2017, of Subpesca, and the SUBPESCA-SERNAPESCA coordinated procedure for the implementation of new aquaculture regulations.
