Sea lice are a group of ectoparasite copepods negatively affecting fish health in the salmon farming industry worldwide. Due to their biology, including several stages of development with different sensitivities to chemotherapeutants and their complex host–parasite interactions, the control of sea lice represents one of the major obstacles for sustainable aquaculture. Interdisciplinary approaches are required to avoid the environmental impacts of antiparasites commercially used during the fish production cycle and the increasing emergence of drug resistance in lice populations. Herein, control methods based on genomic analyses will allow for the development of novel tools such as vaccines, immune‐modulators, in‐feed masking compounds and non‐pharmacological therapies. This review highlights the genomic knowledge on the race between hosts and sea lice, with emphasis on Salmo salar and Oncorhynchus kisutch as host fish species and Caligus rogercresseyi as the main threat affecting the Chilean salmon industry.

“…The management of these organisms is a challenge, and the primary strategies to date have been drawn heavily from the agricultural industry in the development of chemotherapeutants that will either kill or temporarily paralyse attached stages of sea lice, to remove them from cultured salmon (Burridge, Weis, Cabello, Pizarro, & Bostick, ; Rae, ). This approach does have challenges, as some sea lice populations now are starting to show significant signs of resistance to the chemicals controlling their population growth, a trend that is similar to that experienced by the agriculture industry (Agusti et al., ; Burridge et al., ; Carmichael et al., ; Chávez‐Mardones, Valenzuela‐Muños, & Gallardo‐Escárate, ; Denholm et al., ; Espedal, Glover, Horsberg, & Nilsen, ; Helgesen, Bravo, Sevatdal, Mendoza, & Horsberg, ; Helgesen, Romstad, Aaen, & Horsberg, ; Jones, Hammell, Gettinby, & Revie, ; Sevatdal & Horsberg, ; Valenzuela‐Muños & Gallardo‐ Escárate, ). There are also concerns regarding the potential environmental effects occurring within wild species as these chemicals are released into the natural environment (Burridge, Haya, & Waddy, ; Burridge et al., , ; Ernst et al., ; Medina, Barata, Telfer, & Baird, ,; Van Geest, Burridge, Fife, & Kidd, ; Willis, Gillibrand, Cromey, & Black, ).…”

The sea louse, Lepeophtheirus salmonis, is parasitic to salmonid species in the Northern Hemisphere and has become a widespread biological and economic problem for the salmon farming industry. A better understanding is needed of their spatial distribution and early life history to disrupt the life cycle of the sea louse. In this study, sea lice larval densities within salmon farms, between salmon farms and reference sites, and at various depths were quantified using both plankton pumps and plankton nets. Farm sites exhibited significantly higher densities than reference sites; however, these densities dropped an order of magnitude at a distance of 100 m from the cages. The majority of the larvae captured in the study were nauplii (93%), and densities ranged from 0 to 10 larvae/m . Free-swimming sea lice larvae were found to exhibit a diel cycle where nauplii larvae were in deeper waters (10-17 m) during the day and in surface waters (1-6 m) during the night. The results of this study suggest that the early life-history stages of sea lice originate from and may remain close to active salmon farms, creating a self-sustaining population.
