Aquaculture is a rapidly growing field today and is also quite important in terms of healthy food source for humans. Infectious diseases pose the greatest threat to this sector in terms of economics, sustainability, and increased mortality. Uninformed, excessive, and incorrect use of chemical drugs against these diseases causes accumulation in the environment and living organisms, leading to negative consequences that also affect the ecosystem. In addition, the development of resistance in harmful organisms raises a single health issue that threatens the sustainability of the sector. Nowadays, antimicrobial resistance (AMR), considered the most critical issue, generally occurs when bacteria, viruses, fungi, or parasites no longer respond to antimicrobials used at recommended therapeutic doses. As a result, treating diseases becomes more difficult, increasing the rate of disease spread within the herd and mortality rates. Decreases in production efficiency are observed. Parasites pose a major threat to fish health and performance in aquaculture. The issue of resistance to antiparasitic drugs in aquaculture is a current topic that is often overlooked but could have serious consequences in the future. Research is being conducted on the development of resistance in Sea lice, especially Salmon lice (Lepeophtheirus salmonis), which cause many infectious agents to spread and negatively affect growth performance in fish, posing a serious threat to salmon farming in particular. Although numerous approaches have been introduced for the management of salmon lice, field applications still rely heavily on antiparasitic drugs administered through baths or feed. Consequently, cases of multiple resistance, decreased sensitivity, or resistance development have been reported. The aim of this review is to highlight the antiparasitic resistance caused by drugs used to combat ectoparasitic sea lice encountered in aquaculture and to raise awareness among aquatic animal health specialists and veterinarians about potential problems that may be encountered in the future.
