Chile: Experiences in controlling sea lice
Caligus rogercresseyi, a marine copepod found in Chilean waters, is a native parasite which has been transmitted to farmed species such as salmonids. In Chile, this parasite remained under control until the end of 2006, when the threshold of infestation was about the five adult Caligus/fish. This ration grew exponentially in the following year, reaching 34 adult Caligus/fish per site.
