Fish Lice [Caligus]
Description
Caligus is a genus within the family Caligidae, commonly referred to as fish lice. These ectoparasites infest a wide range of marine and freshwater fish species, attaching to the host's skin, gills, or mouth. They feed on the host's mucus and tissues, leading to irritation, increased susceptibility to diseases, and even death in severe infestations. Caligus species are known for their broad host range and are a major concern for aquaculture operations worldwide. Their life cycle includes several planktonic stages before maturing into the adult form that attaches to fish.
