Effects of three pesticides used to control sea lice on the early development of Choromytilus chorus, Sphaerechinus granularis, and Paracentrotus lividus

ABSTRACT: The high production levels of the Chilean salmon farming industry have resulted in the emergence of several diseases that affect all stages of development of cultured species. The parasitic copepod Caligus rogercresseyi is considered a potential vector of pathologies, and different chemica...

The parasitic copepod Caligus rogercresseyi is considered a potential vector of pathologies, and different chemical compounds such as pyrethroids and organophosphates have been used to prevent and control sea lice outbreaks.
