1. A system for protecting fish from parasite infection by disinfecting water from parasites, the system comprising:
a fish guidance system for deterring fish from moving into a first region bordering a water surface and/or for prompting fish to remain in and/or return to a second region away from the water surface, whereas the fish guidance system is configured such that fish can move from the second region into the first region so that they can reach the water surface; and
a radiation disinfection system that is configured to provide disinfection radiation to the first region while the fish are within the second region, the disinfection radiation being ultraviolet radiation configured to disinfect water from parasites,
wherein the fish guidance system comprises one or more light sources configured to emit light only toward the second region and the radiation disinfection system comprises one or more disinfection radiation sources configured to emit disinfection radiation only toward the first region.
